ABSTRACT:
An internal combustion engine having a carburetor-type fuel induction system in which the primary carburetor barrel delivers an air/fuel mixture into a container. The air/fuel mixture is conducted from the container into the intake manifold. A liquid trap is provided between the primary barrel and the container to collect liquid gasoline running down the side wall. This trapped liquid is delivered directly to the intake manifold, resulting in improved cold start performance of the engine. The container is preferably heated by means such as exhaust gas, liquid engine coolant or electrical heaters.
