Engine with blow-by gas treatment and blow-by gas treatment

摘要

PROBLEM TO BE SOLVED: To provide an engine including a blow-by gas treatment device and a blow-by gas treatment device capable of realizing stable oil separation performance when a filter is held by using a fastening member. A blow-by gas processing apparatus includes a separation unit 330 that separates blow-by gas into oil and gas. The separation unit 330 collides the flow velocity increasing operation unit 120 for increasing the flow velocity of the blow-by gas, the filter 130 for passing the blow-by gas whose flow velocity has been increased by the flow velocity increasing operation unit 120, and the blow-by gas passing through the filter 130 with the oil. The collision plate 133 separated from the gas, the fastening member 139 fastened to the flow velocity increasing operation unit 120 and holding the filter 130 between the flow velocity increasing operation unit 120 and the collision plate 133, the flow velocity increasing operation unit 120 and the collision plate. It has a deformation suppressing member 140, which is arranged between the filter 130 and the filter 130 and prevents the filter 130 from being deformed by fastening the fastening member 139.
