Method and system for predictably controlling air/fuel ratio |
摘要 |
A method and apparatus for controlling air/fuel ratio of an internal combustion engine at a desired level of richness or leanness utilizes an existing air flow sensor for sensing air flow into the engine and generating a corresponding air flow signal. A signal multiplier multiplies the air flow signal by a constant to generate a modified air flow signal corresponding to the desired level of richness or leanness. A control signal is then generated for controlling the air/fuel ratio to the desired level.
