Abstract

PURPOSE: To prevent lubricating oil from being abundantly sucked with blowby gas in the cover by processing blowby gas in a locker arm cover only at the time of high load into an air inlet system.
CONSTITUTION: A crank case 3 and an air inlet manifold 4 in an engine 1 is conducted by a first passage 9 equipped with a PCV valve 10 to open and close in proportion to the negative pressure rate, further a locker arm cover 2 and a crank case 3 are conducted to an air inlet pipe 7 in front of a supercharger 6 by second and third passages 11, 12. And, when the engine is in low load, the PCV valve 10 opens, blowby gas in the crank case 3 is sucked through a first passage 9 into an air inlet manifold 4, whereas, when it is in high load, negative pressure in an air inlet pipe 7 is raised, blowby gas in the locker arm crank case is sucked through the second and third passages 11, 12 into the air inlet pipe 7.
