    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： A control system for an engine includes a feedback determination module, a feed-forward determination module, and a valve control module. The feedback determination module generates an exhaust gas recirculation (EGR) feedback value based on engine speed and a difference between desired and measured combustion phasing. The feed-forward determination module generates an EGR feed-forward value based on a difference between desired and measured mass air flow (MAF) rates. The valve control module controls an EGR valve based on the EGR feedback and feed-forward values, an intake manifold absolute pressure (MAP), an engine speed, and an exhaust back pressure (EBP).

    摘要： An internal combustion engine system is equipped with a controllable engine valve actuation system. Controlling lift of an engine valve includes periodically monitoring engine valve lift and engine crank angle. A preferred engine valve lift profile is determined in a crank angle-domain. A preferred engine valve position is determined in the crank angle-domain. The preferred engine valve position is interpolated to determine a preferred engine valve position in the time-domain. The control circuit is actuated to control the engine valve in the time-domain.

    摘要： A method and system for controlling an engine includes a spark ignition (SI) control module operating the engine in a spark ignition mode in a high lift valve state and a pre-HCCI control module entering a matching state when homogeneous charge compression ignition (HCCI) mode conditions are met. When a matching condition is met, the pre-HCCI control module enters a pre-homogeneous charge compression ignition mode and performs spark retardation, stratified operation or lean operation and commands a low lift valve state. The system also includes an HCCI control module entering an HCCI mode and when in the low lift valve state.
