Abstract
An internal combustion engine is provided. The internal combustion engine includes a supercharger that is arranged in an intake passage; an intercooler that is arranged downstream of the supercharger in a direction of intake air flow, in the intake passage; and a blow-by gas returning apparatus. The blow-by gas returning apparatus includes a bypass passage, an ejector, and a blow-by gas passage. The bypass passage connects a first position that is arranged between the supercharger and the intercooler, and a second position that is arranged downstream of the intercooler of the intake passage together. The ejector is arranged in the bypass passage, and configured to draw in blow-by gas from the crankcase through the blow-by gas passage when air flows through the bypass passage from the first position toward the second position.
