Description

The high-pressure direct injection system delivers a precise quantity of diesel to the engine at a specific moment.

K9K

The system consists of:

• a priming pump on the low-pressure circuit,
• a diesel fuel filter,
• a high-pressure pump incorporating a feed pump (transfer pump),
• a pressure regulator mounted on the pump,
• a spherical injection rail,
• a pressure sensor mounted on the rail,
• four solenoid injectors,
• a diesel temperature sensor,
• a coolant temperature sensor,
• a boost air pressure and temperature sensor,
• a cylinder reference sensor,
• an engine speed sensor,
• an accelerometer,
• an exhaust gas recirculation solenoid valve,
• an accelerator pedal potentiometer,
• an atmospheric pressure sensor,
• an injection control unit.
