Description
technical field [0001] The invention relates to an electromagnetic actuator, in particular to an optimization method for an electromagnetic actuator of a diesel engine fuel injector. Background technique [0002] The electronically controlled high-pressure common rail system is the core key system of modern diesel engines, and the high-speed electromagnetic actuator is the core control component of the common rail injector. When the opening response time of the electromagnetic actuator is long, the precision of the fuel injection timing of the common rail system will be greatly reduced, which will lead to the deterioration of the injection consistency of each cylinder of the multi-cylinder diesel engine. When the closing response time of the electromagnetic actuator is long, the needle valve of the injector closes too slowly, which makes the fuel atomization in the later stage of injection poor, and the large particle fuel increases the soot of the diesel engine and deterior...
