    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 system for controlling electromechanical of an internal combustion has a valve-closing electromagnet for attracting the armature coupled to the valve to close the valve, a valve-opening electromagnet for attracting the armature to open the valve, a valve-opening spring for biasing the valve open, and a valve-closing spring for biasing the valve closed. The method includes de-energizing the valve-closing electromagnet for a predetermined time, enabling the valve to oscillate by the valve springs, and then energizing the valve-closing electromagnet to close the valve. Consequently, only the valve-closing electromagnet is energized to open and close the valve. The valve biasing springs force the valve to a location at which the valve-closing electromagnet can close the valve. This provides an electrical energy over prior methods in which both the valve-opening and valve-closing electromagnets are energized to actuate the valve.

    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： A system and method are disclosed for operating an internal combustion to provide a temperature rise in an exhaust aftertreatment device. An exhaust valve is actuated during a compression stroke to release unburned fuel and air. The fuel oxidizes with the air in the exhaust aftertreatment device causing an exotherm. The opening and closing time of the exhaust valve are determined to cause the desired amount of fuel and air to be released into the exhaust aftertreatment device.

    摘要： A system and a method for operating an internal combustion engine at a six-stroke, eight-stroke, or greater number of strokes cycle is disclosed. The combustion of the fuel and air is accomplished in two combustion steps with at least one expansion and compression process in between the two combustions, with the second combustion occurring at a stoichiometric air-fuel ratio. The first combustion at lean air-fuel ratio provides high efficiency. The products of the first combustion are subjected to a second combustion event at stoichiometric air-fuel ratio. Consequently, high conversion efficiency of nitrogen oxides in the exhaust aftertreatment device, available at stoichiometric conditions, can be achieved.
