摘要： A method of controlling valve landing in a camless engine including a valve movable between fully open and fully closed positions, and an electromagnetic valve actuator for actuating the valve is provided. The method includes providing at least one discrete position measurement sensor to determine when the valve is at a particular position during valve movement. The velocity of the valve is calculated at the particular position based upon current and rate of change of current in the electromagnetic valve actuator when the valve is at the particular position. Valve landing is controlled based upon the calculated velocity.

The system (12) includes a circuit (46) for providing current to the coils (32, 34) of electromagnets (16, 18) disposed on either side of the armature (20). The system (12) also includes an electronic control unit (ECU) (50). The ECU (50) is configured to determine the neutral position of a virtual spring corresponding to the combination of forces acting on the armature 20 including the magnetic force of the attracting electromagnet (16 or 18) and the force of a restoring spring (22 or 24) opposing movement of the armature (20) towards the attracting electromagnet (16 or 18). The ECU (50) is further configured to control the current in the coil (32 or 34) of the attracting electromagnet (16 or 18) responsive to the determined neutral position so as to minimize the velocity of the armature as it reaches the pole face (36 or 38) of the attracting electromagnet (16 or 18).

摘要： A method of operating an internal combustion engine in response to a transient load includes the steps of providing an air charge quantity required to produce a commanded air-fuel mixture within the combustion chamber, providing a fuel quantity required to produce a commanded air-fuel mixture within the combustion chamber, and displacing a quantity of the air-fuel mixture from the combustion chamber in response to the transient load. The method is especially advantageous for rapidly affecting engine response to transient loads resulting from sudden load change events, such as traction control, transmission shift and driver demand events.
