Crankcase ventilation system for a hydrogen fueled engine

摘要

A crankcase ventilation system for an internal combustion engine includes a first valve for controlling air flow into the engine's crankcase, a second valve for controlling air flow out of the crankcase, and a separator for receiving air flowing from the second valve and for removing oil entrained in the air. The first and second valves may be spring-operated valves, such as reed valves.
