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 four strokes are: 1  Induction, when the air/fuel mixture is dragged into the cylinder. 2  Compression, where the mixture is compressed and ignited just before TDC. 3  Power, when the mixture explodes and forces the piston down.  Exhaust, when the burnt gases are pushed out of the cylinder.
