Spark-ignition engines are designed to burn gasoline in a controlled process known as deflagration Nonetheless, the unburned combination may autoignite by stress and heat alone, quite than igniting from the spark plug at precisely the appropriate time, causing a rapid stress rise which might injury the engine.
