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.
Detonation is caused by the actual compression of the mixture to a level where it reaches the Auto-ignition point, becoming an uncontrollable explosion, the point at which this takes place varying from fuel to fuel, hence the use of additives to vary this point.
