Question

what is difference between compression ratio and pressure ratio ???

Answer 1

Explanation:

A compression ratio means that the mixture is compressed to one-sixth its original volume by the action of the piston in the cylinder. Pressure ratio - The ratio of the volume enclosed by the cylinder of an internal-combustion engine at the beginning of the compression stroke to the volume enclosed at the end of it.
