Compression ratio

- A value that represents the ratio of the volume of an engine's combustion chamber from its largest capacity to its smallest capacity. In a piston engine it is the ratio between the volume of the cylinder and combustion chamber when the piston is at the bottom of its stroke, and the volume of the combustion chamber when the piston is at the top of its stroke. If, at the bottom of the stroke, the cylinder contains 1000 cc of air and at the top of the stroke it has 100 cc of air, then the compression ratio would be 10:1.

Cylinder configuration

- Cylinders typically contain pistons which are the car's combustion chambers. Cylinders can be arranged in different confirgurations: either in a "V" shape, which is where two cylinders are paired together, or "in line", where they are arranged singly, one after another. If you hear the expression "V8 engine", it means it has four pairs of cylinders. In line, or "straight" means that the cylinders are arranged singly.
