  • Ignition system with ionization detection
    Patent number: 5777216
    Abstract: Provided is a high power ignition system for internal combustion engines with a detection circuit for sensing and measuring ionization in a spark plug gap. The detection circuit utilizes a dual-purpose second energy source to apply the voltage necessary to generate a high current arc and then an ionization current. A signal processor analyzes an ionization signal created by the detection circuit to derive useful ignition system data such as engine misfire, combustion duration, engine knocking, approximate air/fuel ratio, indications of spark plug fouling, and preignition.
