    摘要: Various methods are described for controlling engine operation for an engine having a turbocharger and direction injection. One example method includes performing at least a first and second injection in response to a driver action. The first and second injection may be performed during a cylinder cycle, the first injection generating a lean combustion and the second injection injected after combustion such that it exits the cylinder unburned into the exhaust upstream of a turbine of the turbocharger.

    摘要: A system and method for controlling an internal combustion engine to improve air/fuel ratio control using a feed-forward observer-based control strategy include estimating current and future airflow actuator positions, determining corresponding mass airflow values, and determining a future in-cylinder air charge based on a difference between the current and future mass airflow values. In one embodiment, the difference between current and future mass airflow estimates is used as a feed-forward term and combined with a sensed or measured value generated by a mass airflow sensor prior to being processed using a manifold filling model to predict the future cylinder air charge. In another embodiment, the current and future mass airflow estimates are processed using the manifold filling model with the results used to generate a future delta cylinder air charge that is subsequently used as a feed-forward term and combined with a measured air charge corresponding to a measured mass airflow processed by the manifold filling model.

    摘要: A control system (10) and method for controlling an operational position of a throttle valve in an engine. The system includes a position sensor (16) operably connected to the throttle valve that generates a first signal. A controller is operably connected to the position sensor. The controller (18) is configured to determine a current position of the throttle valve using a transfer function defining a curve with no breakpoints and the signal from the position sensor. The controller (18) is further configured to change the operational position of the throttle valve based on the current position and a desired position of the throttle valve.
