FIELD: motors and pumps.
SUBSTANCE: invention relates to the engine engineering and is intended for fuel supply to diesel engine combustion chambers. The invention ensures tight system displacement on the engine and improves fuel injection characteristics and pump injector unit operation reliability. The fuel supplying system consists of a medium-pressure pump connected to battery hydroline, which is coupled with water driven pump-injector units by fuel supply main lines and by fuel discharge main lines. The pump-injector units are mounted on the engine. The fuel-supplying system is provided with at least one receiver for fuel discharge mounted in parallel to pump-injector units displacement on the engine. Discharging cavity is connected with receiver behind electromagnetic valve of each pump-injector unit. Receiver is coupled with fuel tank by means of the common pipeline.
EFFECT: stable characteristics of fuel injection and creation of optimal conditions for all pump-injector units operation.
