Abstract
In a method of injection fuel for Diesel engine comprising a high pressure injection pump with a fuel supply line for supplying high pressure fuel to fuel injection nozzles wherein a fuel control line extends between the pump and a low pressure fuel supply line for discharge in excess fuel thereto under the control of a magnetic valve which is closed to end the discharge of excess fuel and initiate pumping of fuel, the magnetic valve is opened at the end of fuel pumping at a point corresponding to a piston stroke length h after the upper dead center of the piston such that, when communication between the pump and the low pressure fuel line is established, pressure pulses in the low pressure fuel line are avoided.
