    摘要： There is provided a method for controlling engine valves of an internal combustion engine adapted to selectively operate at one of a first open position and a second open position, including controlling engine operation during a transition from a first to a second combustion mode. The method comprises determining a desired engine airflow based upon an operator torque request. A cylinder intake volume is determined for the desired engine airflow when operating at the first open position. A control scheme is determined to control the engine valves to attain the cylinder intake volume for the desired engine airflow when operating at the second open position. The control scheme is executed and the engine valve is transitioned to the second open position when the cylinder intake volume to operate at the second open position is within a range of authority of the engine valves.

    摘要： 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.

    摘要： An internal combustion engine is selectably operable in one of homogeneous charge compression ignition (HCCI) mode with low lift intake and exhaust valve profiles and spark ignition (SI) mode with high lift intake and exhaust valve profiles. Transition from a current combustion mode to a desired combustion mode includes phase adjusting the one of the intake and exhaust valves exhibiting a greater effect upon an effective cylinder volume for a given phase adjustment in the desired combustion mode based upon a desired phasing for the desired combustion mode prior to lift adjusting the one of the intake and exhaust valves and adjusting the other of the intake and exhaust valves.
