Blow-by gas circulation system for four-stroke IC engine - has air suction unit on engine air inlet with gas blow-by passage located to act without disturbance

摘要

There is an engine cover (1) for the upper section of the engine (E), with an air suction unit mounted on the engine at an inlet end of the engine suction system. A gas blow by passage connects to the engine at the air inlet, in order to allow circulation to reach the air inlet. The connection and mounting units for the air inlet are located such that they do nor disturb the action of the other unit. An oil sepn. chamber is provided to prevent entrainment of oil in the engine inlet. USE/ADVANTAGE - Blow-by gas circulation system for four-stroke IC engine, eg outboard motor for boat, allows mounting of suction device to engine suction system without hinderance of blow-by gas passage.
