PCV VALVE INSTALLATION STRUCTURE

摘要

A positive crankcase ventilation (PCV) valve installation structure for installing a PCV valve (41) of an engine (1) on an engine body (4) includes: a blow-by gas recirculation system (8) that includes a ventilation hose (42) that connects the engine body (4) to an intake device (5) introducing outside air into the engine body (4) and that has a recirculation passage (42a) recirculating blow-by gas arising in the engine body (4) to the intake device (5) and an oil cooler device (9) that exchanges heat between lubricating oil (27) and a medium solution that is lower in temperature than the lubricating oil (27); and a cover (38) that transfers heat of the oil cooler device (9) to the PCV valve (41).
