ABSTRACT:
A crankcase ventilating system removes engine oil particles from a gas containing a blow-by gas and drawn from an engine crankcase, and then introduces the gas into an intake manifold. The crankcase ventilating system includes a first chamber for passing a gas from the crankcase therethrough, a valve for controlling the amount of the gas flowing therethrough, and a second chamber for passing therethrough the gas flowing from the first chamber via the valve and for allowing the gas to flow from the second chamber into the intake manifold. The second chamber is arranged to permit the gas to be expanded therein. The crankcase ventilating system can separate fuel and water from the engine oil.
