1. A method for limiting a peak temperature of combustion in an engine, the method comprising:

  • in a first cycle of the engine;

    introducing fuel into a combustion chamber of the engine under a first set of conditions;

    igniting the fuel in the combustion chamber to cause combustion; and

    measuring acceleration of an engine component in response to the combustion to determine whether the measured acceleration corresponds to a peak temperature of combustion that exceeds a desired temperature of combustion; and

    in a second cycle of the engine;

    based on the measured acceleration of the engine component during the first cycle, introducing fuel into the combustion chamber under a second set of conditions to reduce a peak temperature of combustion in the combustion chamber.
