FIELD: transportation.
SUBSTANCE: invention relates to hybrid vehicles. In the hybrid vehicle ejector flow regulation method, after the engine shutdown command, the control valve of the exhaust device is opened when the engine rpm is between the first and second values. First engine rpm is lower than that of idling. Second engine rpm takes precedence of engine shutdown. In another embodiment, after the first engine shutdown command, the exhaust valve shutoff valve is opened when the engine rpm is between the first and second values. Second engine rpm is nominally higher than that in engine stationary state. After the second engine shutdown command, the shut-off valve is closed or kept closed regardless of engine rpm.
EFFECT: reduced vibration at killing.
