ABSTRACT:
Apparatus and method for use associated with an internal combustion engine whereby drainage of fuel, vapor and oil drainage from the crankcase thereof is recovered and introduced in a metered fashion into the principal fuel line of the engine. A dual-chambered device is employed having an upper chamber connected to the crankcase for accumulating drainage, and a lower chamber serving as a mixing chamber connected in series with the principal fuel line. At the top of the mixing chamber there is mounted a diffuser plate for receiving and dispersing the drainage as it falls from a valve assembly in the drainage chamber directly above. The diffuser plate acts to disperse the drainage in a thin film over the surface of the plate after which the drainage falls off the sides of the plate and mixes readily with the fuel from the principal fuel supply in the mixing chamber. Also provided across the top of the diffuser plate is a channel which acts as a baffle to enhance the mixing action of the drainage with the fuel.
