Abstract

PURPOSE: To prevent the pollution by the oil mist, etc. in an air inlet pipe and a carburetor and in addition its functional deterioration by returning the blowby gas in a crank case to the combustion room of an engine without passing the air inlet pipe.
CONSTITUTION: With reference of a two-cycle engine composed of a cylinder head 4, a cylinder block 2 and a crank case 11, etc., a blowby gas path 30 which communicates the crank case 11 with a combustion room 12 in the cylinder block 2 is equipped, a check valve 31 is additionally set in the middle of this passage 30 and the port to the combustion room 12 is arranged tangentially. When the piston 5 drops excessively, the passage 30 is opened to the combustion room 12, and the blowby gas in the crank case 11 is introduced tangentially into this combustion room 12 through a check valve 31. Thereby mixture with the mixed air can be carried out favourably.
