Crankcase ventilating system and method of removing oil mist from gas in the system
A crankcase ventilating system is described in an internal combustion engine having a crankcase and cylinder block, a cylinder head, a cylinder head cover and an intake manifold. The crankcase ventilating system comprises: a first chamber for passing a gas from the crankcase therethrough; a valve for controlling the amount of the gas flowing from the first chamber therethrough; a second chamber defined in the cylinder head cover 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 has an effective size greater than that of the valve sufficient to cause expansion of the gas upon entry into the second chamber; and means for heating a wall surface of the second chamber. A method is described of removing an oil mist from a gas in a crankcase ventilating system which introduces the gas composed essentially of air, a blow-by gas, and the oil mist from a crankcase into an intake manifold.
