    摘要: A system for controlling intake airflow of an engine includes a mode determination module, a throttle valve control module, and a valve actuation module. The mode determination module generates a mode signal based on an engine speed signal and an engine load signal. The mode signal indicates one of a spark ignition mode and a homogeneous charge compression ignition mode. The throttle valve control module generates a valve control signal based on the mode signal, a temperature signal, and a plurality of valve position signals that indicate positions of first and second throttle valves. The throttle valve control module controls the positions of the first and second throttle valves to regulate flow rates of intake air into an intake manifold of the engine via a heat exchanger based on the valve control signal. The valve actuation module actuates the first and second throttle valves based on the valve control signal.

    摘要: A control system and method for operating an engine includes a transition module that commands engine control from a first homogeneous charge compression (HCCI) mode to a second HCCI mode. The control system also includes a fuel delivery module that operates the engine in a stratified charge operation mode after commanding engine control from the first HCCI mode to the second HCCI mode and discontinues the stratified charge operation thereafter.

    摘要: An engine control system comprises a ringing index (RI) determination module, a fueling threshold determination module, and a combustion mode determination module. The ringing index (RI) determination module determines an RI value of a cylinder of an engine and compares the RI value and a predetermined RI threshold. The fueling threshold determination module determines a fueling threshold and adjusts the fueling threshold based on the comparison of the RI value and the RI threshold. The combustion mode determination module selects a combustion mode for the engine based on a comparison of a current fueling rate and the fueling threshold.
