Patents by Inventor Kyle Earl Edward Schwulst

Kyle Earl Edward Schwulst 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).

  • Electronic engine control with reduced sensor set
    Patent number: 6955081
    Abstract: An engine control apparatus is disclosed for determining crankshaft position, engine phase, engine loading, and intake air mass of an internal combustion engine (10) through monitoring intake air pressure fluctuations (120). The opening of the intake valve (44) is mechanically linked to the crankshaft position of an engine. When the intake valve (44) opens it creates air pressure fluctuations in the air induction system (14) of the engine (10). The control apparatus is configured to determine intake air pressure fluctuations indicative of an intake air event (100 to 110) and thus a particular crankshaft position, and their corresponding period of the engine cycle. The controller then uses this information to determine crankshaft speed and position for the purpose of fuel injection and ignition timing of the internal combustion engine. Engine phase is also determined on four-stroke engines. Intake air pressure is used to determine intake air mass and loading of the engine.
