Abstract:
1. A method of dynamically re-configuring an internal combustion engine coupled to operation of a vehicle, the internal combustion engine being operable in a plurality of modes, the method comprising: electronically controlling one or more cylinder unit associated valve, fuel injection and fuel ignition component states; electronically synchronizing cylinder unit piston position with cylinder unit associated component states to create selected cylinder unit strokes; embodying sequences of strokes defining a plurality of modes into computer readable program logic in computer usable medium; embodying computer readable program logic in computer usable medium to determine engine operation requirements based in part on sensed signals and vehicle operational parameters; selecting cylinder unit operating modes based in part on the determined engine operation requirements and program logic; and configuring cylinder unit component states based in part on the selected sequence of cylinder unit strokes in accordance with the computer programmed selected mode of operation.
