Abstract:
Methods and systems are provided for improving the detection and mitigation of high speed pre-ignition. In one example, high speed pre-ignition is detected based on concurrent or sequential changes in an integrated knock sensor output in a knock window as well as a pre-ignition window. The high speed pre-ignition is addressed using cylinder fuel deactivation and/or engine load limiting to reduce the risk for run-away pre-ignition.

Claim (Index 17):
An engine system, comprising:\n an engine cylinder; a knock sensor coupled to the engine cylinder; a direct fuel injector for injecting fuel into the engine cylinder; an intake throttle; a turbocharger having an intake compressor and an exhaust turbine; and\n a controller configured with computer-readable instructions stored in non-transitory memory for: \n measuring an output of the knock sensor in a first, later knock window over a first number of engine cycles; \n measuring the output of the knock sensor in a second, earlier pre-ignition window over a second number of engine cycles; \n integrating the output of the knock sensor in each of the first, later knock window and the second, earlier pre-ignition window; \n indicating pre-ignition based on the integrated output in the first, later knock window relative to the integrated output in the second, earlier pre-ignition window; and \n adjusting an opening of the intake throttle and a wastegate of the exhaust turbine based on the indicating.
