A VAPORIZED GASOLINE METERING SYSTEM FOR INTERNAL COMBUSTION ENGINES
A prototype vaporized gasoline metering system is described which utilizes engine exhaust heat to vaporize liquid gasoline prior to being combined with inlet air. It is shown that the system (1) exhibits minimal time-fluctuations in air-fuel ratio, (2) essentially eliminates the transient variations in air-fuel ratio due to load changes, and (3) provides a very uniform cylinder-to-cylinder distribution of air-fuel ratio. The use of the vapor system at very lean air-fuel ratios is considered, and a CVS prediction of the lean-limit operation is presented.
