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.

EPG2 makes electric car cheaper

benna — Thu, 04 Mar 2010 13:39:05 +0000

To accelerate the penetration of electric cars in the near future, a company engaged in the field of electricity suppliers component vigorous develop technology “electronics power ” with smaller size and more cheap price. One is Continental which has taken over Siemens VDO from Germany.

According to the company, whereas they are now developing components and complete system of electric cars, namely the energy storage units (batteries), power electronics and electric motors.

Small & Cheap
One improvement is considered significant to the success of Continental power is the product named generation electronic-2 with smaller size, only 30 percent from the previous version. The result, so it’s easy to install, the price becomes more cheaper.

With these successes, electric vehicle components manufacturer believe that transition will happen fast from conventional cars to electric. Moreover, most users of daily car traveled about 100 km.

The main task of power electronics is changing the direct current from the battery into alternating current in electric motors, as well control the work. Power electronics is also used on wasted energy can be stored longer. For example when the car brakes.

In addition, when the regenerative braking energy is active, the system works in reverse, producing more energy to be stored in the battery. There are also additional converter AC / DC are united on the electric power house. Converter is used to change the battery voltage on power supply system or vice versa.

Electric Motor
Continental also uses external synchronous machine called an electric motor incorporated in the transmission. Transmission will change the speed of the car around the motor functions as well as energy management systems.

Type Continental developed the motor works on a wide rev range and it works very efficiently. The result, energy consumption in real driving cycle, both in the city or outside the city, remained frugal. Added, which can produce power the electric motor reaches 60 kW (90 PS). Now is also being developed electric motors that can generate power 120 kW (163 PS).

In City
In the future, electric vehicles will play an important role on the short trip in town or with the distance of about 100 km per day. Based on the survey, most of today’s car owner, use traditional daily vehicle for 100 km farthest.

Based on the survey, showing that most dominant driver of the car is very short travel in urban areas. Two-thirds more than they have to fight through the traffic jammed the city’s growing. the factors that mention cause the use of electric cars will grow faster.

Advantages using electric or hybrid cars in crowded cities, a.k.a reduce exhaust emissions and noise are big enough. This is, not only will help the city, as well as those who have most of the activities in the city.

Meanwhile, car manufacturers from all over the world, also increasingly offer electric cars. Including the prototype for a sports car. Audi for example by e-Tron, Mercedes-Benz with AMG SLS. and BMW has introduced electric cars in the Series-1 which is named ActiveE.

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

S500L, lifestyle and success

benna — Sun, 20 Dec 2009 05:00:44 +0000

Success and achievement in life can be expressed in many ways, and one is to have a Mercedes Benz S500L . Can not be denied that the Mercedes-Benz S-Class C car can be a symbol status for owner, a symbol of success or achievement in life. Or, if expressed in short sentences, you are what you drive….

Sitting in the Mercedes-Benz S500L car is different. The Car which are belonging to the flagship (top model) Mercedes Benz is loaded with innovative technologies, particularly related to safety and comfort. Not only that, the New S-Class also set new standards in driving fun and agility. And, with a New S-Class, automatically lifestyle would be different. The car will enter the sophisticated life with various attributes. Not only that, the term the sky is the limit would not apply to those circles.

who scare of traffic,….
Mercedes Benz S500L can be categorized as car drivers and passengers as well. In other words, the S500L is fun for the driver and also fun for the passengers. This includes rare for full-sized top car which is generally more oriented to the passengers, especially rear seat passengers.

Bearing capacity of 5461 cc engine, 8 cylinder in configuration N ‘(V8), S500L car was stamping a very powerful light on the accelerator pedal (accelerator) S500 L makes the car drove away faster. Speed of 100 kilometers per hour from the stop position can be achieved in 5.4 seconds. Fast enough for a top full-size passenger car.

mercedes S500L tuned and modiffied by carlsson

The maximum power produced by the machine that carries the S500L on 6000 PK 388
rpm and maximum torque of 530 Nm at 2800-4800 rpm. However, because power and big torque transmitted to the rear wheels (rear wheel drive) through the automatic gearbox, with 7 levels of speed tiptronic equipped (7g-tronic), then increase the speed smoothly. Maximum speed S500L electronically limited to 210 kilometers an hour.

However, if you want to enjoy the S500L car engine performance to the limits, the driver lived to kickdown to 4800 rpm and make sure every gear changed between 2800 rpm and 4800 rpm. If not satisfied, the driver can operate the tiptronic, by raising and lowering the gears manually.

No excessive
Manufacturers claim that the New S-Class S500L has set new standards cars in driving fun and agility is not excessive. For an upscale the full-size sedan car, agility S500L is very prominent.

When driving the S500L in the toll roads in a fairly crowded city, the car was pretty quick, so easy to maneuver between the cars that pass slowly through the toll segment.

As the car 5.4 Liter engine capacity, fuel consumption S500L is quite frugal, including a car when compared with the 2.0 Liter engine capacity. With 1 liter of gasoline, S500L can travel as far as 8.9 kilometers. And it might not be a big thing for the owner. Because, if someone had dared to pay approximately USD 2.6 million to buy the S500L, why should you bother with the car gasoline consumption?
And, about the emissions, you do not have to worry, S500L car originally created to meet the Euro 5 standards. However, for L S500 marketed in non-European countries, they have made some adjustments so that L S500 car can use with low fuel quality safely.

Car Design Using Smooth and Special Touch

benna — Fri, 18 Dec 2009 05:00:17 +0000

The design is a combination of function and emotion. And because it involves the emotions, then the touch of the hand (human feeling) on the design becomes very important. Regarding on that issue, the process of designing the car not only can be done with the computer programming. The designer needs to form a real car with the actual size (1: 1) by using clay (clay).

After the clay model hardens, the designer team will feel the indentations of that car with a touch of the hand and they make it perfect form in accordance with the body that they want. After all done, the team will put designers special sheet materials (like stickers) with silver color around parts of the car body. After the entire body covered by a silver special material, passing people will not realize that the car was made from clay. Silver special materials were attached so neatly on the body so that clay model looks like a car in the true sense. And, the next stage then produced the car.

The first stage of designing is sketched. After sketch was completed, then it scanned into the computer and perfected. After the design is considered perfect, then they made a clay model.

designer strengthening car clay model using special hand touch

At first, the car models from clay made in a small scale and after the model perceived perfect then they made a clay model on a scale of 1: 1.

The process of straightening the car clay model design is to use the a small-scale clay model from the original car, and then by hand, the clay model polished using tools such as a thin iron plate, everything is done manually, and with a touch of the hand, so that designers know the strength of his imagination on the design

Goals of the design is to create strength of brand through the world leading design with passion and imagination. That’s according to the DNA of all the car designs that include excellence, cleanliness, simplicity, freshness, and became the main icon. In the design, usually car designer has “4 Design Policy”, which is decisive, creative, consistent, and centered on the consumer.

And in design, designers sometimes use the faces of animals as a model. Design a car with many passengers are sometimes took a model of large animals, and its consistent with the designation of the car as a multipurpose vehicle

Whereas for mini cars or for use in the city typically uses a smaller model for design, but still use the special touch in final settlement.

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

CVT Change Torsion Without Gear

benna — Sat, 17 Oct 2009 17:05:23 +0000

CVT is continuously variable transmission, it is one of the system of automatic power transduction which trend today. Basic Differences between CVT and other power transduction is like conventional automatic transmission and manual, is the way to continuing torsion from engine to wheels

CVT is not using wheel gear for increase and decrease the rotation to wheels. CVT use 2 puli and steel belt. Because no more wheels gear, so at CVT there is no gear comparison like conventional automatic transmission and manual. There is only rotating comparison from lower to higher. Gear change not drastically happen, likewise 1 to 2, 3 and others, and on the contrary

So if the gas pedal pushed and engine burden condition change, CVT will change the rotation compare which will continuously send to wheels automatically. Because of that it is named continuously variable transmission, so the transmission will do compare changing continuously

Basic system

At the CVT there is two puli which connected by belt. For car, because the power that transmitted is huge, so its made from steel [ for bike use belt from rubber]. Puli is the main component at CVT

Special character of two CVT puli is diameter path inside can change. For this, one of the puli side can be shifted, this side can move front and back close to another side which made still and cannot move

The first puli function like power accepter from engine or called rotater puli. After that, trough the belt, these puli continuing the engine power to second puli which is called rotater puli. From this last puli, power transferred to wheels

Power transfer from CVT to wheels cannot be direct, but using gear wheel or differential [last gear compare]

For step a side the puli which are moving, used hydraulic pressured. So this system have pump installed

With one of the side is slip, so the diameter puli path changes. And because the inside of the puli is tirus. Cause changes of diameter path, there is changes happen at the rotate comparison which is transferred fro, rotater puli to rotation puli

When both of puli closing, the path diameter increasing. Otherwise, if pull step away from inside side, the diameter will decrease, and because the differences of this diameter, the comparison of transferred rotation can be change or replace

Because of the main component have only two puli and belt, the construction of CVT become more simple. The amount of the component is more less compare with conventional automatic transmission and manual. Because of that the size is became more compact. At every test which already done with CVT, the consumption of fuel became more efficient

Comparison changes

First time the car start, the first puli diameter is small and the second is bi. The result is engine rotation will decrease when transferred to second puli. And car runs slowly. This condition is using for the first run and for accelerate to. These conditions called low gear comparison

When the engine rotation increased, there is changes at the second puli diameter. Rotater puli, the diameter are increase. But the rotated puli diameter is decrease. And second puli rotation increase and so the car speed increase too. This condition called high gear comparison. Its use for high speed

Converter torque

The last version of CVT is completed with torque converter [TC] increaser or torque converters which like tun shape on its unit. The TC is used to increase the torque, mainly when the car starts. Even so, the engine rotation increase, TC is locked. The engine rotation directly transfers to puli. And power transfer can do in efficient way

CVT and TC now implement at Nissan [Xtrail] and soon Honda Odyssey. When using this TC, so the fluid for CVT same with ATF. And Nissan said, using ATF, the work of CVT to transfer the power will get increase about 30 percent compare if not using ATF

During the time, the CVT only for small cars use. This is because the ability of belt that connected two puli. But the developing of belt stuff and the technology, the car with big engine can start to use it.

For example, Nissan which called his CVT is X-tronic, already use for passenger car 3.5 liter engine. And Honda at odyssey, minivan 7 passenger with 2.4 liter engine. Honda have CVT factory too.

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.
