Which critical failure mode involves the incoming fuel/oxidizer mixture igniting before the spark plug fires due to excessive internal heat?

Answer

Pre-ignition

Pre-ignition occurs when hot internal surfaces, like the cylinder walls or piston crown, reach a temperature high enough to spontaneously ignite the incoming mixture before the intended spark event.
