Best Answer: In an acid-base titration the idea is to carry out a neutralization reaction between an acid solution and a base solution in order to determine the ...
Detonation (not to be confused with pre-ignition) is a spontaneous combustion of the end-gas (remaning air-fuel mixture) within the combustion chamber AFTER the spark/ignition. Combustion of the air-fuel mixture is supposed to be a smooth, controlled burn originating at the spark plug and spreading throughout the chamber, (relatively) steadily increasing pressure and tempurature to drive the piston down.
The pressure is pushing the piston like it's supposed to, and superimposed on that you get a brief spike that rings the engine. CAUSES Detonation is influenced by chamber design (shape, size, geometry, plug location), compression ratio, engine timing, mixture temperature, cylinder pressure and fuel octane rating.
