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

摘要

PROBLEM TO BE SOLVED: To provide an engine provided with 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 device includes a separation unit 330 that separates blow-by gas into oil and gas. The separation unit 330 collides with the flow velocity increasing operation unit 120 that increases the flow velocity of the blow-by gas, the filter 130 that passes the blow-by gas whose flow velocity has increased by the flow velocity increasing operation unit 120, and the blow-by gas that has passed through the filter 130 with the oil. The collision plate 133 separated from the gas, the fastening member 139 fastened to the flow velocity increase operation unit 120 and holding the filter 130 between the flow velocity increase operation unit 120 and the collision plate 133, the flow velocity increase 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.
