Abstract
A reflux structure for blow-by gas that returns blow-by gas generated in an engine to a clean side of an air cleaner to reflux the blow-by gas to the engine, the reflux structure for blow-by gas includes: a communication pipe that has a flow path introducing the blow-by gas from the engine to the clean side of the air cleaner; and an air funnel that is mounted on the clean side of the air cleaner and introduces intake air from a dirty side into the engine, wherein the communication pipe has a discharge port formed to discharge the blow-by gas to a side closer to a bottom than to an umbrella part of the air funnel around the air funnel.
Claims5
A reflux structure for blow-by gas that returns blow-by gas generated in an engine to a clean side of an air cleaner to reflux the blow-by gas to the engine, said reflux structure for blow-by gas comprising:
- a pipe that has a flow path introducing the blow-by gas from the engine to the clean side of the air cleaner;
- and
- an air funnel that is mounted on the clean side of the air cleaner and introduces intake air from a dirty side into the engine,
- wherein said pipe has a discharge port formed to discharge the blow-by gas to a side closer to a bottom than to an umbrella part of the air funnel around the air funnel,
- wherein the discharge port is located directly under the umbrella part, and
- wherein the blow-by gas, after being diffused inside the umbrella part, flows around and expands from the inside to an outside of the umbrella part, and is drawn into an intake flow in the vicinity of a suction port and then refluxed into the engine.
