    Abstract: The invention relates to an operational method for, in particular, a direct-injection internal combustion engine having a plurality of combustion engines, in particular, for a direct-injection spark ignition engine of a motor vehicle with at least partial low NOx-combustion (NAV) and several operational sub-methods. Said method alternates between at least one additional operation sub-method and a low NOx operational sub-method. In the event of the of the low NOx sub-method being ignited by means of an ignition device at an ignition time point (ZZP), a predominately homogeneous, lean fuel/exhaust gas/air mixture having a combustion air ratio of ? =1 is spark ignited in the respective combustion chamber and a flame front combustion (FFV) that has been ignited by the spark ignition converts into a charge compression combustion (RZV). The operational stability in the respective operational sub-method improves due to the variation of the compression ratios e.

    Abstract: A premixed compression ignition type engine is operated while change over between spark ignition combustion and compression ignition combustion. This engine has a negative overlap period during steady operation under compression ignition combustion. In the same cylinder, a valve-closing timing of an exhaust valve during steady operation under spark ignition combustion is retarded with respect to the valve-closing timing thereof after the change over. In a case where an intake valve is first changed over after start of the change over from spark ignition combustion to compression ignition combustion, the valve-opening timing of the intake valve during a change over period from spark ignition combustion to compression ignition combustion is in an advanced state with respect to the valve-opening timing thereof during steady operation under spark ignition combustion.

    Abstract: A powertrain, and a control method therefor, are provided, wherein ignition of a combustible charge in a combustion chamber of a controlled auto-ignition internal combustion engine equipped with in-cylinder fuel-injection and a spark ignition device is controlled. The method comprises generating a spark- discharge plasma channel between the electrodes of the spark ignition device, and igniting the combustible charge. The spark-discharge plasma channel is moved toward and entrained by the combustible charge, effective to advance phasing of controlled auto-ignition combustion.

    Abstract: An engine has a plurality of combustion cylinders with a first piston (3) reciprocably mounted in each of the combustion cylinders in the conventional manner. The engine head has, in communication with each of the combustion cylinders, a cylindrical recess (14) containing a reciprocably mounted second piston (17). On the side of the second piston (17) opposite the combustion chamber is a control chamber (19) with inlets and outlets for controlling movement of the second piston (17). The second piston (17) is used to increase the compression ratio without appreciably reducing the expansion ratio. Alternatively, the second piston (17) may be used as a pump to pump fluid from the control chamber (19). In yet another alternative method of operation, the second piston (17) can be driven outward within the cylindrical recess (14) to an extent which varies in accordance with power demand, thereby varying the compression ratio in accordance with the power demand.
