Fuel pump control system for internal combustion engine varies time of at least one of start and end of effective pump delivery stroke in harmony with change in engine's valve control times

摘要

The control system has a delivery capacity controller for a displacement fuel pump (5) operating in synchronism with the rotation of the camshaft of the engine (10). The controller controls the capacity to a desired value by varying the time of at least one of a start and end of an effective delivery stroke of the pump in harmony with a change in the engine's valve control times
