In car magazines when they quote the compression ratio, what does this mean? I know it must have something to do with the fuel/air mixture or something but what does it actually tell me about the car? Is a lower ratio better? I mean torque and BHP are obvious measures but this has always baffled me.
And while i'm on it, what about bore and stroke? Is bore the diameter of the piston and stroke the length of the rod from the piston to crank? And again, what do altering these things do?
