Hi Frans
I am pretty sure you are thinking ofpre-ignition
that is the real killer. It isa disorderlycombustion of the
fuel- air mixture that will take an engine and quicklyforce it to
play the song "silentNight".Detonation is much less
sinister but over time will cause damage. In an automobile you can hear it
as marbles when you step on the accelerator, anti-knock sensors can adjust
to stop it. If you don't stop the pinging on something that runs at a high
power setting for long periods of time it will do no good for long engine
life. Plugs, valves and pistons will suffer.
