  • Blow-by gas ventilation device
    Patent number: 9447753
    Abstract: A bypass passage connecting an upstream portion and a downstream portion of a compressor of a turbocharger is provided in an air intake passage of an internal combustion engine. An ejector, which utilizes the intake air flowing in the bypass passage as a drive gas and thereby venting the blow-by gas generated by the internal combustion engine, is installed in the bypass passage. When the internal combustion engine is at a low temperature at which the oil is easily degraded by the blow-by gas, the flow rate of the intake air flowing in the bypass passage, that is, the flow rate of the drive gas of the ejector, is increased.
