Description

ABSTRACT:
The engine operating angle at which a determined fuel injection quantity is delivered to the engine is varied in accord with barometric pressure variations to compensate an engine air-fuel mixing time to offset variations in air-fuel mixture homogeneity prior to combustion, promoting complete combustion, increased engine performance, increased catalytic converter efficiency and durability over a wide range of barometric pressure values.
