SISTEMA DE ADMISSAO PARA UM MOTOR DE COMBUSTAO INTERNA

摘要

An induction system for an internal combustion engine embodying a plenum chamber that communicates with the intake system between the carburetor and the engine chamber so as to promote continuous flow even at low speeds to improve low speed charging efficiency. A fuel return conduit separately communicates the plenum chamber with the intake passage for returning condensed fuel in a relatively continuous fashion to the intake passage so as to avoid mixture strength variations.
