Because the engine ECU controls the injection system including injection pressure, injection rate and injection timing, it is not affected by engine speed or load. This can ensure that a stable injection pressure is always maintained, especially in the low engine speed range, and can greatly reduce the amount of black smoke usually emitted by diesel engines during start-up and acceleration. Therefore, exhaust emissions are cleaner and reduced, and a higher power output is achieved.
