FIELD: engine devices and pumps.
SUBSTANCE: control method for fuel supply to a vehicle engine is proposed. According to the method, when the engine is cuts off, a fuel injection pump (FIP) with variable delivery and a drive from the engine operates at a high feed rate and fills in the high-pressure fuel storage with fuel. When the engine is further restarted, the fuel from the high-pressure fuel storage is used, if the FIP runs at a low feed rate.
EFFECT: acceleration of engine deceleration at cutoff, acceleration of engine start-up due to the need to increase the fuel pressure of the high-pressure fuel pump before starting the fuel injection into the engine.
