Detonation involves a supersonic exothermic. Knocking in a engine is spark-ignition internal combustion.
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.
engine knocking hard,and shaking a bit

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.
can a chevy truck with a 350 engine with a tbi cause detonation and pre- ignition?
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.
It could be: A. worn rod or main bearings. If that's the case you'll have low oil pressure. B. a faulty "knock sensor" that's supposed to retard the engine timing when it detects early ignition detonation.
the unburned charge in the cylinders explodes instead of burning normally.
