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.
Pre-ignition: Pre-ignition is defined as the ignition of the mixture prior to the spark plug firing. Anytime something causes the mixture in the chamber to ignite prior to the spark plug event it is classified as pre-ignition. The two are completely different and abnormal phenomenon. DETONATION.
