Japan ZEXEL the TICS system uses plunger Huatao-time adjustment, by controlling the timing Huatao change the location of the pre-stroke piston oil supply, thus adjusting the oil supply time, and can also speed up with the cam to control compatible Injection rate and the injection pressure. Komatsu of Japan has developed a unique combination of variable pre-stroke piston KP2 1 of the fuel pump, Germany-Xu also developed a RP39, RP43-variable injection rate, sprayed Oil timing and control of fuel injection control Huatao-injection pump, its working principles and structure and ZEXEL the P-TICS system similar to, but also to a variable pre-stroke inline pump.

2, Electronic Control Unit Pump System

German Bosch company's Electronic Control Unit Pump (EUP) system that uses a shorter high-pressure pipeline, to achieve higher fuel injection pressure, the maximum injection pressure up to 1 60 MPa. The system uses high-speed electromagnetic valve control injection timing And injection volume.
