  • Method of operating an internal combustion engine
    Patent number: 7832381
    Abstract: A method for operating an internal combustion engine in the form of an Otto engine, especially of a motor vehicle, selectively uses carburetor fuel, especially gasoline or ethanol (E85) by direct injection into at least one combustion chamber of the internal combustion engine by means of at least one fuel injector. Optionally, instead of injecting ignition spark engine fuel or in addition to injecting ignition spark engine fuel, the internal combustion engine is operated with gas, especially CNG (Compressed Natural Gas) or LPG (Liquefied Petroleum Gas). A mixture adaptation value is continuously determined during the operation of the internal combustion engine with spark ignition engine fuel.

  • Four-stroke internal combustion engine with direct injection
    Patent number: 6378486
    Abstract: The invention relates to a four stroke internal combustion engine with applied ignition, wherein fuel is directly injected into a combustion chamber by means of an injector. Said engine comprises at least one admission channel with an admission valve and at least one exhaust channel with an exhaust valve, the admission valve and the exhaust valve being placed on opposite sides of the combustion chamber and the injector being placed on the admission valve side. Said engine also comprises a cavity formed in a piston top. A piston exhibits a central longitudinal axis extending in the direction of displacement of said piston.
