  • Using ion current signal for engine performance and emissions measuring techniques and methods for doing the same
    Patent number: 10815916
    Abstract: A system and method is provided for the use of the ion current signal characteristics for onboard cycle-by-cycle, cylinder-by-cylinder measurement. The system may also control the engine operating parameters based on a predicted NOx emission level, CO emission level, CO2 emission level, O2 emission level, unburned hydrocarbon (HC) emission level, cylinder pressure, or a cylinder temperature measurement according to characteristics of the ion current signal.
    Type: Grant

  • Autonomous operation of electronically controlled internal combustion engines on a variety of fuels and/or other variabilities using ion current and/or other combustion sensors
    Patent number: 10774773
    Abstract: A system and method to enable electronically controlled internal combustion engines to self-adjust parameters and operate properly on different fuels that have wide ranges of physical and chemical properties. Input from a sensor is utilized that gives a signal indicative of the combustion process. The ECU processes the signal and readjusts the engine operating parameters to achieve its operating goals.

  • Ion current use for combustion resonance detection, reduction and engine control
    Patent number: 10443535
    Abstract: A system and method for detection, reduction of combustion resonance and engine control is provided. The system senses ion current within one or each cylinder of a multi-cylinder engine and determines combustion resonance from the ion current signal. In addition, the system may determine an engine control strategy to reduce combustion resonance based on the feedback from the ion current signal.
