Method for controlling combustion mode transitions in an internal combustion engine
An internal combustion engine is selectively operative in one of a plurality of combustion modes. A method for controlling the engine includes commanding the engine operation to transition from a first combustion mode to a second combustion mode. Engine valve operation is commanded to a desired valve overlap and valve overlap is monitored. Engine operation is changed to the second combustion mode when the engine valve overlap achieves a predetermined range or threshold.
