High-pressure fuel control system for DI system

Fuel Control System, which will be a key for DI system, can be provided

  • Controller into which injector, high-pressure fuel pump, and its drive IC have been integrated.
  • Increased dynamic range by drive control optimal for injector characteristics.
  • Improved accuracy of fuel injection volume control by pump and pipe systems which minimize the fuel pressure pulsation, and fuel pressure fast feedback control.
