PROBLEM TO BE SOLVED: To provide an engine capable of preventing freezing of a blow-by gas outlet in cold.SOLUTION: In an engine, a low-pressure EGR outlet 5b opened by a suction pipe 9 is provided at a terminal end 5a of a low-pressure EGR passage 5, and a blow-by gas outlet 19b opened by the suction pipe 9 is provided at a terminal end 19a of a blow-by gas passage 19. The low-pressure EGR outlet 5b and the blow-by gas outlet 12b are arranged at opposed positions across a passage 9 in the suction pipe 9. Low-pressure EGR gas 20 flows from the low-pressure EGR outlet 5b toward the blow-by gas outlet 12b during a predetermined period among engine cold start and warming periods including a cold start period of the engine and a warming period after the cold start period. |
