    摘要: A method and a control module for performing the same include a filter module filtering in-cylinder pressure signals using a filter to form filtered in-cylinder pressure signals. The control module further includes a heat release rate determination module generating heat release rate signals based on the in-cylinder pressure signals and a maximum heat rate determination module determining a maximum heat release rate from the heat release rate signals. The system also includes a correction module correcting auto-ignition for the engine based on the maximum heat release rate.

    摘要: A control system for an engine includes a heat-release rate (HRR) module, a first filter module, a second filter module, an auto-ignition energy determination module, and a corrective action module. The HRR module generates an HRR signal based on in-cylinder pressures of a cylinder of the engine. The first filter module generates a first filtered HRR signal indicative of a first HRR due to combustion in the cylinder by filtering the HRR signal. The second filter module generates a second filtered HRR signal indicative of a second HRR due to auto-ignition in the cylinder by filtering one of the HRR signal and the first filtered HRR signal. The auto-ignition energy determination module determines an auto-ignition energy of the cylinder based on the first and second filtered HRR signals. The corrective action module selectively adjusts auto-ignition of the engine based on the auto-ignition energy. A related method is also provided.
