  • Procedure for the operation of an internal combustion engine
    Patent number: 8156920
    Abstract: Procedure for the transition of an internal combustion engine, particularly a gasoline engine with direct gasoline injection and with a partially variable valve-train assembly, from an initial mode of operation into a target mode of operation, whereby the initial mode of operation and the target mode of operation are either a mode of operation with an externally-supplied ignition or one with self-ignition. The procedure comprises the procedural steps: Adaptation of the operating parameters of the initial mode of operation to the required values for the target mode of operation in a map-based pilot control phase Changeover of the mode of operation after the map-based pilot control phase Closed-loop control of the operating parameters after the changeover.
