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.
A leaky fuel injector can also cause backfire.   If the backfire is from the air intake (air cleaner), then that tells us that a very lean air/fuel ratio condition exists. The mixture explodes in the intake manifold instead of in the combustion chamber.
