FIELD: engine building.
SUBSTANCE: invention relates to vehicles engines. In the hybrid vehicle engine warming-up method, when it is driven by the electric motor, the electrically-driven intake air compressor at closed position of upstream intake throttle valve and with open position of exhaust gas recirculation valve until piston temperature exceeds threshold value. In another version, engine is rotated without fuel supply by means of electric motor torque with frequency lower than cranking frequency of engine crankshaft. An outlet heater connected to the catalytic neutraliser of exhaust gases is used. At the same time the exhaust gas recirculation valve is kept in the open position, and the upstream throttle valve is in the closed position.
EFFECT: possibility of engine warm-up.
