Fuel injection system, control valve and electronic control circuit

摘要

A fuel injection system and control valve are disclosed for use with a multi-cylinder engine such as a diesel or proco type engine. The disclosed control valve, which is of the piezoelectric type, controls the fuel injection into the individual cylinders by being connected in fluid circuit between the high pressure pump and distributor which are contained in the pump and distributor assembly. The control valve contains novel features providing improvements in the system.
