WIPO Patent Application WO/2020/090284
Kind Code:
A1
Abstract:
This engine system comprises: a first PCV passage that has one end portion connected to an intake passage downstream of an intake throttle valve and upstream of a compressor and has the other end portion connected to an engine; a second PCV passage that has one end portion connected to the intake passage downstream of a throttle valve and has the other end portion connected to the engine; and a flow rate limitation means that limits the flow rate of gas flowing through the first PCV passage or the second PCV passage. A portion of air flowing through the intake passage downstream of the intake throttle valve is introduced into the engine through the first PCV passage during a non-supercharging operation in which the air is not pumped to the engine by the compressor.
