Used for fuel pumps to the pressure, through the pipeline for fuel delivered to the common rail, and then use the electromagnetic injector to spray its combustion chamber. Fuel pump for pressure from the electromagnetic valve control, fuel pressure and engine speed and load to match the best value.

Denso Corporation is now used in a fuel injector for each jet fuel, when asked interval is 0.4 S, a five-stroke combustion of the fuel injection action. In order to meet the requirements of different users, Denso Corporation has developed a software, used to compensate the injector when the fuel injector deviation. System itself with a 2 1 D decoder. Each injector has its own value bias, when the engine control system to read every deviation value, the deviation will immediately add value.

And the development of other common-rail fuel system manufacturer, Denso company also is developing piezoelectric common-rail system, the use of piezoelectric technology has each injector will shorten the time interval of the 0.1 S, while also improving the speed injection The.
