摘要 |
A blow-by gas collection passage (91) extends in a cylinder block (1) and a cylinder head (3). A crank chamber (61) is connected to an oil separator (92) through the blow-by gas collection passage (91). A cutout portion is formed in an upper end portion of a wall portion (97) of the blow-by gas collection passage (91), and the oil separator (92) contacts an upper surface of the cylinder head (3) to form a connection portion (98) through which the blow-by gas collection passage (91) is connected to a cam chamber (3A). Thus, new air in the cam chamber (3A) flows into the blow-by gas collection passage (91) at an inlet portion of the oil separator (92) through the connection portion (98) to dilute the blow-by gas.
