Car Technology Trend Heading to Euro 6 Standards (2)

benna — Tue, 09 Mar 2010 11:45:16 +0000

PIEZO Generation injectors and Magnetic. Tight regulations increasing on automobile emissions standards that will be marketed later, is the government’s efforts to reduce emissions. Because the greenhouse effect or global warming even more worrisome. Otherwise are efforts to reduce dependence on fossil fuels. Various ways have been taken. Including made hybrid and electric cars. But implementation is not easy because of many factors to consider.

If the car uses electric power, van be imagine the engine factory foundry would stop production. this industry supported many people on this earth. Their number is many. So reference, last year alone, the number of cars (not including motorcycles), which produced reached 51 million units. Thus, the economic element is also very strong.

Therefore, the transition to electrification, automotive engineers continue to develop the current engine components.

PIEZO injectors
heading to implementation Euro6 regulation, one way that automakers do – work with suppliers – is the reverse component that makes the engine work more efficiently. Important component of machines today’s that determine the efficiency of the engine injector, both for diesel and gasoline.

Introduce new generation of piezoelectric injection and nozzles that use for diesel engine. PIEZO element acts directly on the nozzle needle without the need for an intermediary hydraulic system. In this way the degree and duration of injector opening (work) can be controlled more accurately.

In this way, there are new options. Currently only used multiple injections are still needed by some mechanical components. With the new injector, the actuator also PIEZO works as sensors that report the position of the nozzle needle precisely to the engine computer.

The result, the system itself will control the flow of fuel. Computer machines, in addition to controlling the vehicle, can also detect any change in fuel flow to the injectors. Remarkably again, the computer can adjust the injector individually (their own).

The result, emissions of nitrogen oxides (NOx) can be derived. Fuel consumption is also so much more efficient. Nitrogen oxide emission reduction achieved Euro6 standard, close to 80 mg / km, from the previous Euro5, 180 mg / km.

Development of the hydraulic injector design is also able to optimize the engine work. It has been proven by millions PIEZO common rail systems in use today. At present PIEZO fuel injectors, is returned to the tank could be lowered to 40 percent.

The result, CO2 emissions in passenger cars that use diesel can be minus one gram per km. Another positive outcome is to supply fuel to use a lower-pressure pump. This part reduces the cost of components.

Magnetic injector
For gasoline engines the more vigorous injection system directly, the latest generation injectors in magnetic work. According to Continental, they managed to develop a new XL3 generation injector capable of minimizing the volume of injection. This is a new option from the system already in use, ie multiple injections or also known as the gradual injection (stratified).

The result is a more efficient combustion, more fuel consumption and the main target of CO2 emissions plus the lower component prices more affordable.

Car technology trend heading to Euro 6 standards

benna — Sat, 06 Mar 2010 14:58:37 +0000

Despite the development of automotive technology today lead to electrification, but the motor fuel, like petrol and diesel engines will remain dominant in the next few years. That is the conclusion made by the world automobile components manufacturer.

Some of the company is intensively introduce and develop technology engine components, transmissions and other parts of the vehicle.Consumption & Emissions.

The main target component manufacturers are trying to make products that can meet the standards in accordance with regulations made by the government. For example, the European Union has agreed, Euro6 already applied to cars being produced from 1 September 2014. A year later, all new vehicles must meet these standards.

European standards are too high and still far from perfect. But certainly, Euro6 have been “forced” and automobile component manufacturers to create trends of automotive technology.

Obviously, the target to be achieved is to decrease emissions of carbon dioxide (CO2) gas that causes the greenhouse effect or global warming, nitrogen oxides (NOx). With the decline in emissions, fuel consumption is also becoming more efficient.

Product or critical components that have been developed is fuel supply system (pump), injection systems, engine management (engine control unit or ECU), transmission, sensors and actuators.

Because there are several components that are being developed, this article was written in several series. The first part is about the fuel pump to work according to the needs of the machine.

Fuel pump.

The Efforts to reduce CO2 emissions has begun to put gas in the tank. However, these pumps work at constant speed to supply gasoline to the engine (injectors).
Now, the pump is designed to work in accordance with the requirements or engine working conditions. Like example, when the vehicle is constant (stationary) or running low, the pump down cycle. The goal is to save energy. Conversely, if you want fast, turn the pump up or to work faster and supply so much more amount of fuel.

For this, some factory develop complement pump with a control chip works. Chip mounted on the flange in the gas tank and can be used to control the working of pumps that works with AC current or DC.

This chip will then communicate with management systems (computers) to determine the condition of the engine machine work and then used as parameters control the speed of the pump. More precisely, the work adapted to the needs of the pump engine.
According to Continental, this method can reduce one or two grams of CO2 per km. This was achieved because the electrical power usage is lower. Remarkably again, designed for gasoline and diesel engines.

Hybrid Make Cars Greenest

benna — Thu, 24 Dec 2009 03:18:23 +0000

Several automotive exhibitions were sluggish because global crisis does not seem to happen only in America. As Germany was, the great concern covering an automotive exhibition in Frankfurt, which is known as the IAA Frankfurt Motor show some time ago, because some car manufacturers and automotive components are not present to show their products.

However, the spirit for keeping sustainability of Earth’s environment are felt at that European country, because each car company figure out how to preserve the environment through environmentally friendly cars

Individual manufacturers were vying to produce the lowest CO2 as low as possible and save fuel consumption. One of them is by creating a hybrid engine.

Maybe some people still don’t know about hybrid engines, because not many cars with hybrid engines are milling at street today, and knowledge of the hybrid engine is still not widely known, for that matter the following is a glimpse of hybrid engines.The activator of car which have hybrid technology has 2 different engines , one unit gasoline or diesel engine and an electric engine or a can be called as well as generator. The main engine used is gasoline engines / diesel. But the relatively small size and has a smaller power than a normal car engine. When the gasoline engine / diesel engine spin move with a relatively high / excess at the same time the electric machine transform the rotation energy from the engine with relatively high / excess into electrical energy and then stored in a special battery.

This excess energy is arising from gasoline engines / diesel. Example: Movement of the car on a flat road. Hybrid engines using motion energy which is generated by the gasoline engines / diesel. This happens when the driver releases the gas pedal and the brake pedal. This could be called Renewable energy or energy that can be recycled or reused

If the energy stored in batteries will use at any time, the stored energy automatically will channeled directly to the electric machine and then electric machine converted into energy of motion. For example when the car in a rising or when the car wants to precede.

The car can think wise.
For example when waiting at the crossroads / traffic lights, petrol engine / diesel will automatically turn off. Gasoline / diesel will also turn off when braking and when the engine is not committed compression. Hybrid cars do not need a place to charge batteries such as mobile phones, because the battery will be filled automatically by an electric engine. Both these machines can work together with using computers and sensors that have been programmed based on need. Hybrid cars are environmentally friendly cars and energy efficient.

For more details, I will repeat again explanation above in more detail, hybrid cars are cars that have a dual drive system, called “hybrid” (in terms of agricultural means cross-breeding hybrid). In this car, there is a “marriage” between the drive with a conventional gasoline and electric drive with energy

compact hybrid engine at Honda

Hybrid cars combine two energy sources, which can be done in two different ways:

Hybrid Parallel, Hybrid Parallel has a fuel tank that supplies gasoline to the engine. This type of hybrid also has a battery that supplies electric power to the electric machine. Both gasoline engines and electric engines can drive transmission at the same time, and then the transmission will drive the wheels. In this type of gas tank and gas battery is connected to the both engine independently and its resulting that both an electric engine and gasoline engine can produce propulsion.
Hybrid Series. It different with hybrid parallel, at the series hybrid the gasoline engine work as a generator that serves a battery or electric motor power generator that drives the transmission. Gasoline engine is never directly being vehicle propulsion. Hybrid series systems Work starting from the fuel tank that supply fuel to engine which then supplies power to the generator, then the resulting power generators are distributed to the battery and electric engine. Energy in the battery itself that produce from the generator is also generated during braking. Power of the electric machine move the transmission and then move the wheel.

Work of machines with the principle of power regenerative (rechargeable / recharging when the vehicle is in operation) on hybrid engines, different from a full electricity car. The car can not recharge electricity, when the electricity runs out, batteries / battery must be charged in particular with a time of 8 to 12 hours (for the technology on board charger). Special hybrid engine, electric engine can recharge the battery using kinetic energy during braking (regenerative braking). Even some of the energy from gasoline engine / solar / bio fuels when working can be channeled to fill the battery / batteries. With this operating system there will be fuel economize.

Work of Parallel Hybrid Car
With the help of an automatic clutch you can choose what mode will be used as long as we drive, whether using an electric engine whose using energy source from the battery or the mode “energy recovery (Battery charge)” without hindering the excessive rotation of gasoline engine / diesel when we use this energy recovery mode.

Electrical machines can enable without reliance petrol engine / diesel, which means we can freely choose what engine we will use as we wish. Because of that hybrid cars can be combined with a machine that has a capacity of 3-cylinder up to large-capacity 8-cylinder.

There are several modes in this hybrid engine working, bellow is the detail describes
Conventional mode.
Hybrid-parallel machines work / move like normal cars that use gasoline engines / diesel engines, the energy channeled from engine to the wheels of vehicles. During this works process the electric machine and its components are off.
Electric mode
Under these conditions the electric machine is the prime mover, electric engines energy source from batteries and also in this condition gasoline engine / diesel is off.
Accelerate mode
Under these conditions the vehicle is in a high speed state requires large energy/power, and in this condition electric engines and gasoline engines / diesel works at the same time. Under these conditions the electric engines have electric energy supply from the battery.
Energy recovery mode
when the vehicle is doing the breaking with help by electric machine, at that time the electric machine (generator) produces electric energy. This concept is the same as bike lights that use electric energy with the help of the wheel rotation or the dam turbine that changes the energy of motion into electrical energy. Electrical energy generated during braking and then stored in batteries. In this condition the automatic Clutch in free conditions so that the rotation of gasoline engine / diesel is not having disturbance or obstacles
Energy saving mode
In this condition the gas engine / diesel engine rotates with a high rotation at the same time little part of motion energy which resulting from high turnover machine used by electric engines that served also as a generator (producing electricity) which later are stored into the battery and most of the motion energy are channeled directly to the wheels of the vehicle.When Start

How it works when the car active running

step by step hybrid works when running

When Start	Low Speed	Normal speed	When Mode 4WD	While speeding	Reducing the Rate and Braking
Power comes from the front and rear motor using battery power	the car is only driven by the motor using battery power	The battery is switched off and replaced by gasoline enabled through the CVT to achieve fuel efficiency	Gasoline engine is front- wheel power source, while the rear wheels are driven by the back motor as additional power required	Power comes from the gasoline engine and front motor .Rear motor provides additional power when needed	Front and rear motors function as generators and charge the battery

That is the hybrid engine, the detail explanation above may be changed according to the application of future technology, I hope the above explanation can be useful to improve the science readers of this blog

Knowing Start Stop System At Mazda

benna — Mon, 19 Oct 2009 17:07:08 +0000

This is the technologi that prided up by mazda in early 2009, they call it SISS [smart idle stop system]. Actually that start-stop technology is use for energy efficiency and make car with gasoline engine more environment friendly, mainly when in the city with having more rush hour

The way to turn the car on again [restart] different from another company, the other company turn on the engine again using starter motor, and mazda using fuel inject direct to burning chamber

Not stress

This way is calimed by mazda more better because engine can turn on fast compare when using starter motor [convensional] because with motor starter. Late happen. So when the gas pedal pushed the engine cannot fastly turn on and and make car move slowly. Like when the engine start from beginning

Beside more better and not generate stress plus worry, the fuel consumption can be economize almost 10 percent, especially in rush street. Because this better technology, starting this year, mazda will aqquiped all main product which is sale at 2009

Start stop system [mazda call it “stop-Idle] will turn of the engine automatically when the car doesn’t move. For example when stop waiting red light or street totally rush. But for turn on again driver easily only push the pedal

Mazda system beginning engine start with fuel injected direct to cylinder when engine dead. Fuel burnt and make piston moving. So that engine do it again the work process, piston must stopped at exact position for create air balance volume every cylinder

For this, SISS doing exact control for piston position as long as engine dead. And also index every cylinder and start to inject fuel before engine round.

With this way, engine can turn on again in just 0.35 second or a half of time needed by engine that adopt stop start system using electric motor conventional

Fuel Eeconomize Driving Technology in Audi

benna — Thu, 15 Oct 2009 17:04:06 +0000

More Germans luxury cars is equipped by fuel economize technology, one of that car is audi, starting april 2009 some of his product equipped by stop-start system

Not just that, like what trend in F1 arena, audi is using energy which is drop out when braking and turn into electric energy. And another additional is modular program efficiency. For that cars equipped by computer with energy efficiency program, the result is, car is not inform the fuel consumption when it use, but also give tips how to drive efficient

Start-stop system developed for having fuel economize when car is using intown or in rush hour, and its work like this, the system will turn off the engine when car stop, engine will turn off when transmission bar in neutral position and the driver loose the clutch pedal

When, clutch pedal pushed again, the engine will start again. This system works fast and fluent, the engine will its own stationer when the drive change gear. Especially for car is still using manual gear box

Audi joined start-stop system with high tech efficient battery technology, for take care of system still good working on low temperature. System not work when engine when engine warming up, so that the lubricant can be hot soonest, and also the outgas filter can works normally. The driver also can turn it off with only push the button

Base on test by audi, when it driven in standard condition, start-stop system will reduce fuel consumption about 0,2 litre / 100 km and drop the CO2 emission about 5 g/km. the system use first time at Audi A3 TFSI, Audi A4 and A5 2.0CC, all with manual transmission. Audi says that some of product will completed by this start-stop system

How to drive, a new audi way for lowing fuel consumption isusing efficient modular program, and one of them is driving

For that, car will equipped wth efficient computer program, Audi call it Audi driver information system. All the data of the fuel consumption will shows at monitor palced in the middle of dashboard. The car will suggest the driver how to drive in efficient way. Base on the research, driving style affect the fuel consumption almost 30 percent

This efficiency program will continuously analize fuel consumption and give tips to driver how to economize the fuel with situation and driving style

For this, indicator placed near the gear box bar which is give the signal to driver to soon to change the gear for economize fuel optimal .

4 x 4 or 4 x 2

benna — Thu, 17 Sep 2009 17:01:56 +0000

With the electric motor directly on the wheel, the option to use the system of 4 x 4, 4 x 2, rear wheels and the movement as a more simple and flexible. Each wheel can only use one or the motor system is also called 4 x4. Simpler again, when the two front wheels only been the electric motor, the car was a 4×2.

Although Venturi Volage uses a battery, but Michelin hopes to moves energy from the vehicle can be fuel cells or capacitor. Therefore also, in addition to working with the Venturi, tire manufacturers also make electric cars with other companies, namely Heuliez and Orange.

Through Maw, Michelin would like to provide evidence that the system can be applied to concept car passengers and goods. With this technology is expected, practical solutions will need transportation in the city, can be missed. At the same time reduce the pollution in the town center with a vehicle that continues crowded

In fact this technology has been introduced 12 years Michelin Lau. However the moment not quite fit. Now, with the high prices of fuel and demand environment is more stringent, Michelin regard, technology can already commercial.

With Maw, Suspension not works mechanism, but electricity. This unique system able to work with the response time is very fast, that is 0.003 seconds and symptoms shaky and practical swinging lost.

However, Michelin does not mean the system does not have this weakness. Because the main use of electrical work and installed in the wheel again, for the area that often floods, of course, is less suitable. Except, when the system is able to create a partition that is completely anti-flooding or water seepage.

Hybrid Electric Cars and Alternative Energy

benna — Sun, 13 Sep 2009 16:58:19 +0000

In an effort to reduce environmental pollution or global warming, car manufacturers have succeeded in creating cars that can use a variety of alternative energy. Among others, hydrogen, fuel gas (CNG) and the last is also popular electric car.

However, among the vehicle, the hybrid option is still a major producer. Terrible, not hybrid concept, but is marketed in bulk. One example is the Toyota Prius and Honda Insight.

Problem
Alternative energy sources, such as hydrogen, fuel gas really interesting. The problem for the fuel type of infrastructure that is needed is quite expensive. This is due to the nature of gas; be compressed, which causes very high pressure. As a result, the required weight of the tank and also a special handling.

In other cases, electric cars are very interesting. The problem, mileage for one time charging is very limited. Infrastructure to recharge is not available, especially in public places. In addition, the time needed to recharge the battery is still relatively long. Consequently, the most fitting solution is hybrid.

Source
Not like the hybrid. They have Two Source activator motor fuels (conventional engine) and electric motor. The lack of two sources is cost or price that more expensive compared with only one engine. In addition, the technology also add complex.

Conversely, the benefits hybrid car, the fuel consumption is very economical. Plus the other value of friendly to the environment. Hybrid car owner is a person who participated reduces global warming, is now increasingly worrisome condition.

Hybrid car owners will not face problems such as a car on electricity, hydrogen or fuel gas. Condition is the same with cars that are now used as the fuel or diesel fuel that can be obtained in almost every fuel station

Main source of hybrid cars are still burning in the engine (internal combustion). Oil is a source of energy (gasoline or diesel). Both types of fuel is easily obtained.

So, as the additional energy and is used in certain conditions, used electric motor. Move the last to obtain electricity from a battery. In other cases, obtain energy from the battery engine, electricity from the house, and the brake is used during recovery.

Economize
In fact; the energy produced by machine can not be used for all to activate the vehicle. Some energy wasted for example, to casually system, muffler, engine parts, transmission parts and rub against each other plus.

Even when the car is braking, casually energy wastes. Components of the brake wheels are so hot. Precisely, the energy of the machine movement was changed to heat energy. Well, at the present time hybrid car, energy is recycling again.

When braking the car, the kinetics energy converted into electricity. How, as the wheel or in the transmission been generator. Electricity generated by the generator, when the main rotary engine, and when braking the car, converted into electricity. Furthermore, electrical energy is stored in the battery

Electric motor
On certain conditions, when the car would push gas (acceleration), the car no longer control the machine to raise the lap. Computers will control the power the car’s electric motor to obtain a source of energy from the battery.

Even, if necessary, during heavy traffic jammed, cars and roads spread, simply by using electricity. Main engines do not need to live. Conditions have created a hybrid car is far more economical.

In other cases, when the energy decreases starting at the battery, the main engine will work like a car now. Besides can be used to cover travel, of course, the rate is used in battery. Even hybrid cars are the current-use lithium-ion battery, can be filled quickly. Simply chop the electric to home electric slot!

Revealing KERS in F1

benna — Mon, 07 Sep 2009 16:51:45 +0000

spirit for economize energy and green environment, has now entered to the F-1. This is marked with a plan of FIA (Federation Internationale d’Automobile) use KERS next year (2009). KERS, Kinetic Energy Regenerative (can also Recovery) System is taking more wasted energy when braking the car. In this way, the fuel consumption becomes more economical. Waste gas emissions, especially CO2 can be also reduced.

When the car braking, engine still running. Energy generated in machine is not used optimally because the car slowed or even stopped total. Means that the output waste useless. Waste form of energy or movement lap engine component called the energy kinetic. Energy that is captured stored and later used to run vehicles.

There are two ways of utilizing energy kinetic, namely mechanical and electrical. Mechanical, is using the flywheel. While electrical, using energy from the engine power to be changed (using the generator), and stored in the capacitor or battery. And next the engine is used to help run the vehicle, for example accelerated. Because the two sources of energy called a hybrid. In the F1, KERS offered Flybrid mechanical work. The engine energy that wasted when braking the car stored in a flywheel of energy kinetic or called lap. The future of energy is used again when gas pushed.

Simple and Practical

KERS actually already developed by many automotive companies. Development led to the recovery of energy electrical. Therefore, when the FIA has the use of KERS, some F1 teams to test direct-try. In fact, each of the F1 teams uses their own KERS system. For example, just as a BMW. As a result, there were incidents, mechanical BMW center stung when touch the side pot and hold the wheel while training.

According Markuus Duesmann, Head of Transmission BMW, the mechanic atung because the resulting voltage AC system KERS car high. After review, BMW KERS control unit turns the high voltage capacitor that came on the 12 volt system used car. Voltage is flowing through the column and chassis made from carbon.

FIA choose the main factor because mechanical KERS package size and more compact than the electrical version. Weight of the entire unit is only 24 while the volume of 13 liters volume. This condition is considered to be very fit for F1 cars.

Mechanical KERS will be used in F1 and created by Flybrid from the UK. Energy savings that can be created from the tool company that is about 400 kilo joule spring lap. When converted again with the same 80 hp or 60 kW for 6.67 seconds. When more simplified, a 60,000 Joule spring second.

Flybrid claim some experts doubt about the energy and automotive. According to them, the energy average of gas containing 39.5 Mega Joule / liter. Therefore, claims 60 kJ, with the same burning 0.00151 liter or 1.5 cc / sec were too excessive. The fuel may not deliver energy 39.5 MJ / liter, and so converted into mechanical energy. Energy experts predict, these tools can only save energy 3kW for 20 seconds.

KERS electrical already widely used at this time by car to the public company, the system still Flybrid less efficient. According to Luca Marmorini’s Toyota F1, Toyota KERS system on the hybrid sport car, the Supra has won the endurance race at Tokachi, Japan is able to restore the energy lost up to 70%. Flybrid mechanical system while only 20%. Therefore, also, he KERS rate Flybrid working with the Totorak and Xtrack less high tech even primitive. In fact Flybrid has award winning, “Engine Innovation of the Year” in Köln, Germany years ago for this KERS

In fact, the calculation is made based on the F1 engineers, the use of KERS has not been able to accelerate the time per lap in significant. The time available to take the energy is 6.5 seconds per lap library. If there are any, can only be faster 0.1 – 0.3 sec / lap. That is not yet taken into account the distribution of weight and size of the packaging. However acknowledged, with the KERS, the opportunity “overtake” bigger is better because traction especially when the car accelerated again.

How to Work

KERS electrical used by car company at this time, energy taken from the wheel. Furthermore, energy is stored in the battery. Energy from the Battery is used to rotate the electric motor. Electric motor is used to help the main engine for accelerate the car or the equipment, such as AC and other electrical. Another way that is quite interesting is adopted as Volvo, with system ISG, (integrated starter-generator). Starter and generator units are the same. While machine working it is turned on and the start the motor when engine is starting the generator to produce electricity.

In the system created by Flybrid, major components of flywheel and CVT (continuously variable transmission) installed between the transmission and rear axle of wheel. If the car braking, the comparison of CVT lap speed flywheel is 6: 1. Flywheel rotates faster and save energy from the engine that is not fully used to run the car. Once the gas deep push, the CVT ratio now turn the flywheel to the transmission channel energy to strengthen the traction or speed acceleration. On Flybrid, lap flywheel to store energy to reach 64,500 rpm.

Although KERS Flybrid oke votes for energy recovery, some experts are still worrying security problems. The round of the flywheel is very high, the bearing (bearing) timeworn fast, and fall can cause the metal fraction. Best Flybrid, security aspects are considered first. Therefore also, flywheel made of carbon and put in a strong steel tube.

The Power on Desmodromic and Pneumatic

benna — Sat, 05 Sep 2009 16:48:11 +0000

At any posts previously discussed about the valve. This valve spring covered task is to restore the valve to the position after the free pull up by rooftop.
The higher the round engine, also cause problems on one spring involutes this. spring must move more quickly. While the spiral is made of metal has a harmonic frequency. If you exceed the limit of its ability, spring will be broken. Surrounding components and the engine took ideas can no longer work.

Therefore, in the engine cars with a round of public higher or characteristics of two-sport use. this because the valve components made from metal, when the heat change in size. This condition is caused with the rift between the valves and the trigger different working machines. This is also the valve bears hydraulic. On this type, slit valve when hot and cold because the same is automatically set by engine oil pressure.
In fact, the engine uses two spring also not enough engineers to meet the desire of the engine, especially those working in the racing arena. on racing arena the engine capacity is limited. And the engine must be able to exert power as much as possible so that the car much go faster.

As an example, the F1 engine capacity 2400 cc, capable of producing 850 hp. Machine cycles to reach 14,000 – 15,000 rpm, and even exceed between 18,000 – 20,000 rpm. The use of mechanical valves spring hydraulic or on such conditions can not be relied upon again.
Desmodromic
Thus was born a new creation, namely Desmodromic (the motor) and the engine valve pneumatic on F1 and Moto GP (Honda now tried again), but still using the same four stroke engine.

Desmodromic, currently used on the Ducati, and no longer use the spring to return the valve to the position after the first peak by punch up. To encourage the throttle level, this system is considered to be simpler but still have only limited because the mechanical work.

Pneumatic
more votes, but complex and expensive. This also causes a limited application in the racing arena. Pneumatic on the valve, the task of spring is replaced by a gas tube high pressured. The principle works the same as the gas shock breaker. Type of gas used by the same, namely nitrogen.

This gas was selected because of the influence of stability in high temperature. However, because the engine temperature is very high, pressure can be changed drastically. To overcome this, the system is equipped with a valve dispose wind.
Although that the principle is simple. Its does not rise to Wearing and tear on the valve from the other series. Pneumatic require SIL or divider that you a very. The pressure pneumatic circuits reach 2500 psi (170 bar). When the sill broken-down, history has been finished for racing engine and this often occurs in the F1 racing arena.
Valve pneumatic first used by the Renault engine in the RVS-9. Then it installed in Lotus car used by Ayrton Sena, on the 1986 racing season. Round of the Renault engine has reached 19,000 rpm.

Because of the complexity pneumatic and valve system is still using rooftop or cam (cam), the actual engine experts have found the other systems, namely electrical hydraulic and electromagnetic. In fact, until now has not been reliable. Therefore, the pneumatic valve assessed at this time as its top.
But that, of the engine engineers never stop to get a more efficient valve works. This is also in accordance with the demand of energy conversion and the environment

Common Rail Diesel vs Conventional Engine

benna — Tue, 01 Sep 2009 16:44:45 +0000

The difference between modern diesel engines, common rail is the way to the conventional fuel supply. In particular components that reside between the injection pump and injector. There are two main components here, the injection pump or mechanical pump commoner called Bosch and injector.

How common rail will use with the same concept of life. In this case, all the solar injector supply directly to the engine, vessel or rail using the same. Is the same as that used in the fuel injection system? While conventional diesel engines, the supply of solar injector get their own directly from the injection pump.

Pressure in the fuel rail is very high. Now, the common rail is next to the generation-3, the pressure reach 1800 bar. If converted to PSI which is still used now is 26,100 PSI. Compare with the tire pressure of 30 PSI. Gas tube or 25 bar and 200 bar CNG. With pressure as is, fogging will be generated. result of the Burning is the machine work becomes more and more efficient
