ABSTRACT:
A system for blow-by gas return to the combustion chamber of an engine according to the present invention including an oil separator with an inlet communicating with an outlet through a diffusion chamber and a filter element; said oil separator communicating with the crankcase of the engine through a breather and an inlet pipe, and also communicates with the intake manifold of the engine through an outlet pipe, so as to separate the oil from the blow-by gas almost completely. The oil separator and the inlet and outlet pipes are disposed in a space directly over the cylinder head of the engine and the intake manifold, so as to prevent ice accumulation therein by the radiation and convection of engine heat thereon. The diffusion chamber of said oil separator is also in communication with the atmosphere by an atmospheric passage so as to prevent the flow of oil into the combustion chamber when unusually large quantities of blow-by gas are produced and the back pressure in the intake manifold becomes unusually low.
