Summary: | 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. |
