ABSTRACT:
This invention provides the combination of a gas-mixing chamber, and a first conduit connected to the crankcase of an engine and passing through the chamber in non-communicating fashion, the conduit then extending out of the chamber and returning to open into the chamber. The first conduit is of copper or at least has its inner wall made of copper. A second conduit leads from the chamber and connects to the intake manifold of the engine. A third conduit leads from the chamber and receives heated gas from the exhaust pipe or manifold. A fourth conduit leads from the mixing chamber and is adapted for connection to the air filter of the engine.
