Mitsubishi Triton Service Manual and Diagram

Mitsubishi Triton Service Manual and Diagram The common rail system uses a type of accumulation chamber called a rail to store pressurized fuel, and injectors that contain electronically controlled solenoid valves to inject the pressurized fuel into the cylinders. Because the engine ECU controls the injection

system (injection pressure, injection rate, and injection timing), the injection system is independent, and thus unaffected by the engine

speed or load. This ensures a stable injection pressure at all times, particularly in the low engine speed range, and dramatically decreases the amount of black smoke ordinarily emitted by a diesel engine during start-up and acceleration.

As a result, exhaust gas emissions are cleaner and reduced, and higher power output is achieved. The supply pump draws fuel from the fuel tank, and pumps the high pressure fuel to the rail. The quantity of fuel discharged from the

supply pump controls the pressure in the rail. The SCV (Suction Control Valve) in the supply pump effects this control in accordance

with commands received from the engine ECU.
