BMW will be launched soon a new automatic transmission with has eight gear acceleration (8-speed) which is developed by ZF. This gearbox will be mounted on the luxury sedan BMW 7-Series. Interestingly, in addition to more efficient, cheaper price compared with the 6-speed. Even with a performance comparable intensity 7-speed dual-clutch on the BMW M3 that was introduced years ago.
And this luxury car manufacturer in Germany is still focused on the transmission system following a dual clutch for models with a large machine
“Automatic Transmission 8-speed developed by ZF can compare with the transmission double clutch. It is more lightweight, efficient and profitable in a matter of cost. The double-clutch transmission is expensive and heavy, and only match in the car with a longitudinal engine and rear wheel movement.
The 8-speed transmission of the results of ZF is designed for cars and the movement behind the wheel all wheel drive (AWD). In fact, it is appropriate for some models of BMW and Audi launched this year. From the results of the tests, ZF transmission was 3 spring cent more economical (fuel), and 6 percent (diesel), compared with a 6-speed.

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
Before using common rail, we told about the machine that is now used in general based on fuel oil. there are only two types, namely gasoline and diesel.
Among the techniques, diesel engine known as CI (compression ignition) engine with the ignition or compression. Meanwhile, gasoline engine called SI (spark ignition) engine with spark ignition (spark plugs).
In the diesel engine, combustion is triggered by the air or be compressed in the cylinder. Due to compression, the air pressure becomes very high. The same temperature reaches the highest point of diesel fuel. Therefore, the solar injected to the air, burned directly. In this way, does not require diesel engine ignition system or spark fireworks.
To get the high pressure, the difference in compression must be high. For diesel engines is ranging from 16 to 25: 1. Meanwhile, gasoline engine 6 – 12: 1. Comparison of compression determines the efficiency of a machine. The higher the comparison of compression, the engine will more efficient. However, comparison of compression can not be determined by the board. Must also consider the nature and quality of fuel that will be used
Technology “Common Rail” vessel is the gods for the modern diesel engine. With common rail, diesel engine into the car class or exclusive premium cars such as Jaguar and BMW 7 Series. City car also does not escape from the obsession with the diesel engine is the latest technology.
For example, Fiat has successfully created 1,300 cc diesel engine equipped with a 70 hp with fuel consumption of 3-4 km or liter/100 average 25 km / liter. So diesel engine is not only owned the truck and bus community large or heavy equipment and ships. Read more…
The valve is one of the most important part of the machine, which works primarily with the principles of the four steps (4-no). Function together like the valve in the heart of man. This is the valve that regulates the amount of fuel and air that can enter the engine and then converted into energy
Next, the valve is also tasked to set up “waste” to be removed so that the burning mixture of fuel and air is still fresh to go smoothly to the engine. To set, new energy that will be burned and the pulp removed, is done by a different valve. The Name is valve and sucking dispose

If the legendary phone showing at legendary museum of modern art, new york, so that phone have special design.
Concept project form nokia which named “MORPH” not only have amazing design, but also unik.
This gadget that still shape in model can be formed as we wish to be, like watch, flattened like video player, or flipped like classic handphone. The electronic component inside this phone which is designed by Nokia not yet been ascertained. This component will be integrated inside transparent cashing.
Although it can be flipped, according to developer, the surface of this phone will still clean and shiny. This impresses like always new.
The key from the ability for being flipped is the nano technology. Nokia research this technology together with university of Cambridge. Later, this technology will using flexible stuff and stable for main element. This Morph hand phone still in design from nokia scientist. The material for this phon not yet developed and nokia will apply this nano technology for cell phone start 2015.
By the time you plug the flash or external hard disk into the USB port on your PC or note book, instantly Windows operating system knew and run autoplay function. from a window, you can select the option to open a folder in the flash or run a software MP3 player to it. What if you do not want autoplay is active when an external data storage device connected to the USB port? its Very easy. Follow these tips.
If you want, this function can be disabled by changing a registry entry.
To turn off the autoplay function that can run the files from the external data storage such as flash disk, you can use registry Windows. For that, you need to open the registry editor. Type “Regedit” in the menu “Start Run”: after registry editor open, got to the key “HKEY USERS I CURRENT_ Software ~ Microsoft ~ Windows
~ Policies ~ CurrentVersion Explorer “. Note entry is in the right window. Double click on entry” Nollrive Type Autorun “and replace 91 existing values in the” Value data “to be 95. After that, click” OK.
After you finish changing the value in the entry “No Drive Type Autorun”; you can close the registry editor program. For these tips, you have to restart the PC for work well. If you want autoplay function is active again later, you just change the return value on “Value data” to 91. These tips apply to all external devices connected to the USB port.
For administrators who want to try one of the interesting features of the ‘, Windows Server 2008 but did not want to be bothered with the settings and configuration may comfortable. Now “there is freeware GUI-based mini ‘, which can perform initial configuration’, Server Core quickly and easily.
One feature of Windows Server 2008 is of great concern among the administrator is Server Core. different with Microsoft habit that always rely on the GUI (Graphical User Interface) facility for easy user interaction with the system, Server Core is “just” a system of environment with minimalist (limited facilities and lack of window) which provides service specific server, such as the AD Domain Services, AD Lightweight Directory Services, DHCP Server, DNS Server, File Server, Print Server, Streaming Media Services, or IIS (Internet Information Services or Internet Information Server). False, if a very minimalist character makes Server Core barn earned the nickname of “Windows without Windows”. So, do not hoping able to see programs like Outlook Express, Calculator, Windows Paint, Wordpad, Windows Messenger, and moreover Media Player in there.
Immediately secure server ore when you first run with his Firewall configuration.
If the flashdisk is broken and your flashdisk does not even detected by the computer .you have certainly somethings that you want to do is to try to formate. but sometimes the format is still no effect whatsoever. because your flash not either detected by the system to your computer.
sometimes there is an incompetent way to resolving problems like this.
if you dare to try and slashing open the plastic casing shroud flash, open using a knife or razor blade (be careful not to slip a side your hand will bleed later). then you will see the all inside flash . Read more…
