Common Rail Diesel Injection 

The fuel dispersion device (injector) is used to disperse fuel to suit the operation state displaying exceptional response and the compression device (compression accumulator, rail) that allows precise electronic control

When the solenoid valve is opened by receiving electrical signal from the DCU, fuel is directly dispersed within the cylinder at a high pressure.

DCU: The most suitable fuel dispersion rate and timing signal is delivered to the injector by collecting and calculating the operation information of the vehicle from each sensor.
