What is the diesel term for detonation?

Explanation:
Knock is the diesel term for detonation. In a diesel engine, fuel is injected into highly compressed, hot air and normally ignites in a controlled, steady way as combustion progresses. If ignition occurs explosively and prematurely, a sharp pressure pulse—detonation—is created, which you hear as a knocking sound known as diesel knock. This differs from pre-ignition (ignition before the intended timing due to hot spots), misfire (a cylinder failing to ignite at all), and backfire (flame traveling back into the intake or exhaust). So the correct term for detonation in this context is knock.
