Abstract:
PROBLEM TO BE SOLVED: To enhance flexibility of layout while reducing air bubbles from oil supplied to a sliding surface of an engine.SOLUTION: A lubrication device includes a gas-liquid separating section 42 to which blow-by gas discharged from a cylinder 22 is introduced to separate the blow-by gas into gas and oil and that stores the oil separated from the blow-by gas; and oil pressure-feeding means 53 for pressure-feeding the oil stored in the gas-liquid separating section 42 to a sliding surface 22a between the cylinder 22 and a piston 21. A blow-by gas introduction passage 44 is connected to the gas-liquid separating section 42 to introduce gas on the inner side to an intake passage 11.
