MITSUBISHI L200 DIESEL COMMON RAIL SYSTEM

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.
