BLOW-BY GAS REDUCTION APPARATUS

Abstract: A blow-by gas recirculation apparatus which can release freezing of a PCV valve in a short period of time is obtained with a simple configuration. The blow-by gas recirculation apparatus is provided with the PCV valve at a case member of a gas space portion to which blow-by gas is sent in a manner that the PCV valve penetrates through the case member and a return path supplying the blow-by the gas, which is from the PCV valve, to an induction system of an engine. A heating portion to which part of oil lubricating the engine is supplied and thus which heats the PCV valve with heat of the oil is formed.
