ABSTRACT:
The combustion efficiency of an internal combustion engine is improved by providing reservoirs in the plenum floor of the intake manifold to collect liquid fuel which precipitates out of the air-fuel mixture. A venturi is mounted in each manifold conduit and is connected with the reservoir by passages which lead to a port in the downstream, low pressure end of the venturi. The air-fuel mixture flowing toward the engine cylinders passes through the venturis and draws the liquid fuel into the flow stream, causing it to atomized into fine droplets that burn more completely in the combustion chambers. A modified form of the invention uses a venturi to receive and effect atomization of liquid fuel from a fuel injector, thus allowing the fuel injector to utilize a relatively large injector port which is less susceptible to clogging than the hair sized ports of conventional fuel injectors.
