FIELD: internal combustion engines.
SUBSTANCE: invention can be used in supercharged internal combustion engines. Method for supercharged engine (10) consists in that the vapor flow from crankcase (144) is blocked through valve (50) with electric control by means of adjustment of valve (50) with electric control in response to detected actuation of braking mechanism with reduced level of underpressure in braking booster (160) with simultaneous activation of driving flow through aspirator (22), connected to brake booster (160). Provided is evacuation by passing the driving flow through aspirator (22). Control valve (50) is electrically controlled to activate the vapor flow from crankcase (144) and completely block the driving flow through aspirator (22) in response to the increased level of vacuum in brake booster (160), and in response to the excess air flow in engine (10) of flow rate threshold.
EFFECT: technical result consists in increasing crankcase ventilation when creating the required vacuum.
