    摘要: A system and method are disclosed for operating an internal combustion engine in which the intake valves are electromechanical valves and the engine has direct fuel injection. By opening the intake valves during the intake stroke when the piston is moving at its maximum speed, the turbulence through the intake valve is enhanced, thereby increasing combustion speed, and hence combustion stability at low torque, low speed operating conditions. Furthermore, if the fuel injection interval occurs when flow of gases through the intake is highest, air-fuel mixing is improved.

    摘要: An engine system and method are disclosed for controlling pre-ignition of an alcohol fuel. In one embodiment, the fuel injection timing is adjusted to cause the fuel to avoid combustion chamber surfaces. In another embodiment, the fuel injection timing is adjusted to spray the fuel directly onto the piston surface to cool the piston. Also disclosed is a cylinder cleaning cycle in which engine knock is purposely caused for one to hundreds of engine cycles by adjusting the fuel content away from alcohol toward gasoline. Further measures to cause knock which are disclosed: adjusting spark timing, intake boost, exhaust gas fraction in the cylinder, cam timing, and transmission gear ratio.

    摘要: A method and system for operating an internal combustion engine. The internal combustion engine is operable in a plurality of compression ratio operating modes. The method includes determining a relationship between a base engine threshold load where the high compression and low compression provide substantially the same engine fuel consumption and engine speed. The determined nominal relationship is modified by a factor, such factor being a function of a condition under which such engine is operating, to obtain a modified relationship. The modified relationship is a function of engine speed and the condition has an effect on knock generation in such engine. The modified relationship and engine speed are used in selecting one of the plurality of compression ratio operating modes for the engine. A hysteresis load as a function of engine speed is determined and applied to the determined hysteresis load to the modified relationship to inhibit switching oscillations between a pair of the plurality of compression ratio operating modes.
