  • System for optimizing the performance of internal combustion engines
    Patent number: 5168853
    Abstract: An engine performance optimizing system is described that requires only a single engine parameter (shaft revolution time) to be measured. By simultaneously dithering spark timing, air/fuel ratio and/or EGR rate in accordance with a predetermined cyclic pattern, and measuring shaft speed during each discrete phase of the dither cycle, correction factors can be computed and used to adjust the spark setting, the air flow and/or the recirculation rate in a way that causes engine performance to be enhanced in terms of fuel economy and lowered emissions.
