ABSTRACT:
A two cycle crankcase compression diesel engine having reed type checks valves for controlling the flow of air into a crankcase chamber though an intake passage. The engine is provided with a separate lubricating system in which no lubricant for lubrication is delivered to the intake passage upstream of the check valve. The closing noise of the check valve is dampened by delivery small quantities of lubricant to the intake passage solely for this purpose. In one embodiment, this lubricant is derived from the crankcase and in another embodiment the lubricant is supplied directly from the separate lubricating system.
