PROBLEM TO BE SOLVED: To provide an engine that can suppress failure of closing of a blow-by gas inlet 3a and a blow-by gas outlet 3b of an oil separator 3 when it is cold.SOLUTION: An engine includes a breather chamber, a breather chamber outlet pipe 2, an oil separator 3, an oil separator outlet pipe 4 and an intake passage 5. The breather chamber 1 is connected to a blow-by gas inlet 3a of the oil separator 3 via the breather chamber outlet pipe 2, and a blow-by gas outlet 3b of the oil separator 3 is connected to the intake passage 5 via the oil separator outlet pipe 4. The engine further includes an engine cooling fan 6. The blow-by gas inlet 3a and the blow-by gas outlet 3b of the oil separator 3 are disposed on the rear side of the oil separator 3 when the blowing direction of engine cooling air 6a sent by an engine cooling fan 6 is set as a rear direction.SELECTED DRAWING: Figure 1 |
