FUEL SYSTEM FOR AN INTERNAL COMBUSTION ENGINE

摘要

A fuel system for supplying fuel to an engine includes a nozzle positioned to direct fuel into a combustion chamber and an electromagnetically operable pump for suplying fuel to the nozzle. A first electronic means supplies power to a winding of the pump to cause delivery of fuel and holds the pumping piston of the pump until it is required to fill the pumping chamber of the pump. A second electronic means partly energises the winding or another winding when the required amount of fuel has flowed into the pumping chamber, to hold the piston against movement.
