SISTEMA DE INYECCION DE COMBUSTIBLE PARA SUMINISTRAR COMBUS-TIBLE A UN MOTOR DE COMBUSTION INTERNA

摘要

A fuel injection system includes a pump including a pump plunger and electromagnetic means for actuating the plunger against the action of a spring. The electromagnetic means includes a winding which is energized to cause delivery of fuel. First electronic means is provided to cause energization of the winding when delivery of fuel is required and second electronic means operable to cause de-energization of the winding. The second electronic means includes a comparator which receives a required fuel signal and a signal from a transducer which provides a signal representative of the plunger position. When the predetermined movement of the plunger has taken place the winding is de-energized to allow the plunger to return under the action of the spring.
