Detonation involves a supersonic exothermic. Knocking in a engine is spark-ignition internal combustion.
Knocking is a rattling noise caused by abnormal combustion in the engine, typically due to improper fuel octane or ignition timing. Detonation is a more severe form of knocking where the air-fuel mixture explodes rather than burns, leading to increased pressure and temperature that can damage the engine. Both can be harmful to the engine and should be addressed promptly.
When the engine detonates its referring to the engine giving spark to the compressed air/fuel in the cylinder, when theres combustion its simply the explosion that happens after ignition.
When an engine runs as it should the fuel/air mix in the combustion chamber ignites at the spark plug and the flame front spreads from there. In an engine that's knocking there are hotspots in the combustion chamber causing the fuel/air mixture to ignite prematurely a bit all over the place.
They are the same thing. They cause damage by applying the force of combustion to the piston before it has reached the top of its stroke, which basically pushes it "backwards"
knocking noise
Because diesel is ignited of heat and high high compresion not a spark on lower compresion petrol engine. If you use diesel in a petrol you will end up with your engine knocking and pre-detonation followed by your engine blowing up pretty bad.

A knock sensor is a device that senses detonation. Detonation occurs in the engine when the fuel begins to burn prematurely; it can cause substantial damage to the engine.
