Latest Patents

Jones holds a patent for a "Method and apparatus for detecting ionic current in the ignition system." This invention provides a method and circuit for detecting low-level ionic currents. An ionization detection voltage is applied to a spark plug, and the resulting output voltage signal is sent to a threshold device. The output voltage signal is developed by a low offset operational amplifier. First and second serially connected Zener diodes carry current in a normal diode direction when a spark event occurs and carry current in their Zener breakdown mode upon recovery from the spark event. A second operational amplifier and its associated feedback circuit generate a guard voltage, which is applied to the junction of the two Zener diodes. The guard voltage is regulated to track the input voltage to the circuit at the cathode of the first diode. Because the guard voltage is essentially the same as the input voltage, there is no leakage current flow through the first diode. Consequently, the output voltage signal developed at the threshold device is attributable exclusively to ionization current, allowing for the detection of very low signal levels. The resulting signal from the threshold device is utilized in detection logic with other vehicle signals to provide a misfire output signal to detect misfires.
