Electromechanical Fuel Control Actuator Issues in Genset Application

In diesel engines, the electromechanical fuel control (EFC) actuator plays a vital role to regulate the fuel flow rate and pressure. It uses electrical energy to actuate the fuel valve, usually mechanical valve and control fuel pressure injected into diesel engine. The rotary and linear actuators are most common in diesel engine and selected based on space constraints and its reliability. As EFC actuator plays critical fuel controlling function in engine, the issues with EFC during engine operation could cause engine dysfunction. This paper studies the major issues observed with EFC actuators which has led to engine operation failures in genset application.
