On the fuel demand of a motor attractive a fuel supply system

摘要

It is a system without feedback for supplying fuel from a tank with fuel injection into an internal combustion engine of a motor vehicle, which is provided as a function of the fuel demand of the internal combustion engine. The pump delivers more fuel than in the operation of the internal combustion engine is required, and the excess fuel is of the internal combustion engine via a bypass force material pressure regulator and derived via a switch which can be actuated by means of fluid, which in dependence on the throughput of the excess fuel passing through the switch in an electrically open and an electrically closed position can be moved is returned to the tank. An electrical control circuit responds to the state of the switch on and changes the size of the current supplied to the electric motor, in order to change the operation speed of rotation and, as a result, the throughput of the fuel discharged from the pump as a function of the fuel demand to modulate the internal combustion engine.
