PROBLEM TO BE SOLVED: To provide an internal combustion engine which can prevent droplets of oil from being suctioned to a suction device even when a suction port for a blow-by gas is blocked by the oil.SOLUTION: An engine 100 (internal combustion engine) includes an engine body 10 having a combustion chamber 12, an intake manifold 5, and an oil separator 6 for separating oil included in a blow-by gas BG. The oil separator 6 is connected to a first suction path 6a communicating with the inside of the engine body 10 below the combustion chamber 12, a discharge path 6b communicating with the inside of the intake manifold 5, and a second suction path 6c communicating with the inside of the engine body 10 above the combustion chamber 12. The second suction path 6c is provided with a one-way valve 66 which is provided in a closed state and is opened on the basis of the increase of a negative pressure in the oil separator 6.SELECTED DRAWING: Figure 1 |
