Diesel common rail and  supporting components are regulated by computer


How it works injector common rail diesel engine is not the same as conventional diesel engines. Here, the injectors work using a solenoid or electrical technology. In the old machines, injectors work with hydro-mechanical. Even in the final version, Third generation, PIEZO- electric injectors.

Modern diesel engine injector with injector engines that use gasoline injection system. In this case, the injector is activated by an electric current that is set by the computer.

The amount of diesel fuel will be governed by the length of spray nozzle opening. Computers regulate these injectors work based on information received from other sensors, such as engine rotation, pressure regulator, fuel pressure, the temperature of diesel, gas pedal position, engine rotation, cylinder, turbo pressure, air flow, cooling water, vehicle speed and onwards.

The circuit components are clearly not necessary or is not present in conventional diesel engines. Computers also determine the time of injection (injection timing) based on signals received from sensors in or crutches as the flywheel.

Thus, common rail diesel engine, able to meet the expectations of many people. To reduce vibration for example, is done by spraying the fuel in stages to prevent a big explosion if done at once.
In other cases, because the pressure on fuel supply system is very high, smaller molecules and spray evenly. Result, the burning was smooth and uneventful. High pressure common rail continuously improved for diesel engines the future.


Now, the diesel engine experts have started from the pressure to raise the bar in 2000. With such a high pressure coupled with the ability to set the time of injection computer more flexible, experts have concluded that diesel engines will no longer need a glow plug to start the engine in the morning. Way, simply by delaying the time of fuel spray.

Another attraction is the diesel engine turbocharger. Comparison of high compression, making better match turbo diesel engine gasoline ketimbangan. Therefore do not be surprised, the ability to produce diesel engines will equal the power of gasoline engines. While efficiency could not matched by the gasoline engine.

Generation Common Rail:
1: injector solenoid working premises with an injection pressure to 1350 bar
2: solenoid injector with an injection pressure of 1600 bar ampai
3: PIEZO injectors with a pressure of 1800 bar.
