  • Supercharged internal combustion engine and method for monitoring whether the crankcase vent has been connected
    Patent number: 8261548
    Abstract: A supercharged internal combustion engine in a motor vehicle includes a venting device for the crankcase of the internal combustion engine and a compressor for supercharging the internal combustion engine. A discharge opening for discharging the crankcase gas is provided upstream of the compressor and a sensor for determining the charge pressure of the compressor is provided downstream of the compressor. The discharge opening is connected to the crankcase by a first connection for the airflow, in particular a hose connection. In order to cost-effectively monitor the venting of the crankcase of the internal combustion engine, an opening, to which the charge pressure of the compressor is applied, is provided downstream of the compressor. The first connection for the airflow includes a closing device for closing the opening to which the charge pressure is applied, wherein the closing device closes the opening if the first connection is connected to the discharge opening.
