Abstract
An internal combustion engine includes a supercharger, an oil tank, a scavenging pump, a first passage, a second passage, and a one-way valve. The supercharger is provided in an intake passage. The oil tank communicates with a crankcase via a collecting passage. The scavenging pump is provided in the collecting passage to transport a fluid in the crankcase to the oil tank. The first passage connects an upper space located above a liquid surface in the oil tank and a downstream portion of the intake passage located on a downstream side with respect to the supercharger. The second passage connects the upper space and an upstream portion of the intake passage located on an upstream side with respect to the supercharger. The one-way valve is provided in the first passage and allows the fluid to flow only from the upper space toward the intake passage.
