ABSTRACT:
This invention relates to a computer controlled fuel system for an internal combustion engine including a low profile carburetor for permitting engine operation on very lean fuel/air ratios without sacrificing engine performance during critical engine operations such as start up, warm-up and acceleration. The low profile carburetor provides a single point source fuel dispersion and includes one or more throttle controlled, sliding plates for increasing fuel entrainment at low engine speeds by increasing the velocity of the airstream flow through the carburetor just before the dispersion point and by maximizing the lateral distance between the point of fuel dispersion and the carburetor airstream. The computer controlled system includes various threshold circuits for providing additional fuel and/or water injection into the carburetor airstream upon detection of predetermined engine conditions.
