Patents by Inventor Patrick Haenel

Patrick Haenel has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10208691
    Abstract: A process and a system for preventing pre-ignition in an internal combustion engine (ICE) includes detecting an ionization level of a combusted gas from a cylinder of the ICE during gas exchange and for a given combustion cycle i. When the ionization level is greater than a reference ionization level a pre-ignition countermeasure prior to and/or during an immediate subsequent combustion cycle i+1 is executed. The ionization sensor may be part of a spark initiating device of the ICE or be a separate ionization sensor.
    Type: Grant

  • Patent number: 9869262
    Abstract: A process and a system for preventing pre-ignition in an internal combustion engine (ICE). The process includes providing an ICE that has a combustion chamber and an exhaust. Also provided is a total hydro-carbon (THC) sensor in communication with the combustion chamber. The THC sensor senses a THC level of the combusted gas for a given combustion cycle i (THCi) of the ICE. In the event that THCi is greater than a reference THC level (THCref), a pre-ignition countermeasure prior to an immediate subsequent combustion cycle i+1 is executed. Furthermore, the executed pre-ignition countermeasure prevents pre-ignition from occurring in the immediate subsequent combustion cycle i+1 of the ICE.
