    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.

    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.

    摘要: Two intake valves are independently operated by electromechanical actuators and activated by the engine electronic controller. One tumble-type intake valve and one conventional intake valve are provided in each cylinder. The valve members are individually opened and closed to achieve a desired air flow pattern in the combustion chamber to optimize combustion which increases fuel economy and reduces undesirable emissions. The opening and closing of the valve members depends on the engine speed, engine load, and other factors.

    摘要: An electromagnetically operated valve assembly (28) has a first solenoid (58) and a second solenoid (60). An armature (56) having a valve stem (54) coupled thereto is positioned between the first solenoid (58) and second solenoid (60). A controller (12) is coupled to the first solenoid (58), the second solenoid (60). A current sensor (49) is coupled to the first solenoid and generated a signal corresponding to the induced current in the first solenoid. The controller (12) changes a voltage applied to the first solenoid from a first polarity to a second polarity. The controller (12) is further configured to hold the voltage at the second polarity for a predetermined time period and a predetermined amplitude to decrease the induced current. The predetermined time period or the predetermined amplitude is determined based on the first signal.
