Patent ID: 8261548

Claim:
A supercharged internal combustion engine of a motor vehicle, comprising: a venting device for a crankcase of the internal combustion engine; a compressor for supercharging the internal combustion engine; a discharge opening for discharging crankcase gas into a fresh air intake path, the discharge opening being arranged upstream of the compressor; a sensor for determining charge pressure of the compressor, the sensor being arranged downstream of the compressor; a first flow connection for connecting the discharge opening to the crankcase; a second opening, to which the charge pressure of the compressor is applied, the second opening being arranged downstream of the compressor; a closing device included in the first flow connection, the closing device closing the second opening to which the charge pressure is applied; wherein the closing device closes the second opening if the first flow connection is connected to the discharge opening; and wherein if the first flow connection is disconnected causing leakage at the discharge opening, the closing device is disconnected from the second opening.
