The engine has a knock sensor that communicates with the Engine Control Unit (ECU). ECU handles the air-fuel mixture, the fuel injectors, and the timing of the ignition. When unburned fuel/air mixture beyond the boundary of the flame front is subjected to a combination of heat and pressure for a certain duration (beyond the delay period of the fuel used), detonation may occur. Detonation is characterized by an almost instantaneous, explosive ignition of at least one pocket of fuel/air mixture outside of the flame front. A local shockwave is created around each pocket, and the cylinder pressure will rise sharply – and possibly beyond its desig…
