摘要： An oil decantation system for an internal combustion engine includes at least one main wall provided with a through-opening for a flow of blow-by gas and a separator device arranged downstream of said through-opening in the direction of travel of said flow of blow-by gas. The separator device includes a valve provided with a decantation component capable of retaining the oil contained in the blow-by gas and of allowing a flow of purified blow-by gas to pass through, wherein the valve is pivotably mounted on the main wall so that its inclination with respect to the main wall varies as a function of the flow of blow-by gas.

摘要： A ventilation system for a crankcase for the transport of blow-by gases from the crankcase to the intake section of an internal combustion engine with supercharger. A ventilation line reaches from the crankcase to the segment of the intake section between the supercharger and the air inlet valve. An air-oil separator is arranged in the ventilation line, as well as a return line for the return of oil separated in the air-oil separator via a tank and a tank outlet valve into the crankcase. An actuating element is arranged in or at the tank. The actuating element is charged with the pressure in the intake line behind the supercharger as working pressure and which upon sufficiently high pressure transports the oil present in the tank via the tank outlet valve into the crankcase.

摘要： 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.
