PROBLEM TO BE SOLVED: To provide an internal combustion engine capable of preventing moisture included in blow-by gas from freezing and blocking a blow-by gas pipe when outside air temperature is low, without complicating a structure.SOLUTION: A blow-by gas outlet portion 6B is disposed above a turbo supercharger 15 in an engine body 6, and a blow-by gas inlet portion 13B is disposed at a position near the blow-by gas outlet portion 6B in a vertical direction, at a part extending in the vertical direction of an intake pipe 13. A blow-by gas pipe 21 is disposed so as to extend from the engine body 6 to the intake pipe 13 in a horizontal direction. At an upper part of the engine body 6, a cover member 20 covering a part of the intake pipe 13 and an air cleaner 11 is disposed. The cover member 20 is provided with a blow-by gas pipe covering portion 20A which projects out from the upper part of the engine body 6 to an upper side of the turbo supercharger 15 in the horizontal direction, and covers an upper side and a side part of the blow-by gas pipe 21.SELECTED DRAWING: Figure 4 |
