Abstract:
1. A ventilation control apparatus for an internal combustion engine, comprising: a supercharger including a compressor disposed at an intake passage of an internal combustion engine and an exhaust turbine disposed at an exhaust passage of the internal combustion engine; a first bypass passage connecting a portion of the exhaust passage upstream of the exhaust turbine and a portion of the intake passage downstream of the compressor; a first PCV passage connecting, at a midway point in the first bypass passage, a cylinder head of the internal combustion engine and the first bypass passage; and first gas introducing means disposed at a connection point between the first bypass passage and the first PCV passage, the first gas introducing means for introducing blow-by gas flowing through the first PCV passage to the first bypass passage using a differential pressure between internal pressure in the exhaust passage upstream of the exhaust turbine and internal pressure in the intake passage downstream of the compressor.
