Abstract
The blow-by gas recirculation device includes first to third passages and first and second check valves. The first to third passages respectively connect a portion of an intake passage downstream of a throttle valve, connect a portion of the intake passage downstream of an intercooler, and connect a portion of the intake passage upstream of a compressor to an interior of the crankcase. In the first passage, a first check valve is configured to permit a flow of gas from the interior of the crankcase to the intake passage and restrict a flow of gas from the intake passage to the interior of the crankcase. In the second passage, the second check valve is configured to permit a flow of gas from the intake passage to the interior of the crankcase and restrict a flow of gas from the interior of the crankcase to the intake passage.
