How do engine compression ratios work? compression ratio, in an internal-combustion engine, degree to which the fuel mixture is compressed before ignition. A compression ratio of six means that the mixture is compressed to one-sixth its original volume by the action of the piston in the cylinder. …
Is higher compression ratio better? A higher compression ratio (CR) is beneficial for engines. That’s because the higher ratio allows for an engine to extract more energy from the combustion process due to better thermal efficiency. Higher compression ratios allow the same combustion temperatures to be achieved with less fuel.
Does higher compression mean more power? A higher compression ratio — say, from 12:1 to 14:1 — means higher combustion efficiency. Higher compression ratios and combustion efficiency mean more power with less fuel, and fewer exhaust gases.
How does compression ratio affect power? Even with engines having fixed valve timing (non-VVT), the effective compression ratio changes as the engine speed and load change. In short, if it changes the amount of charge in the combustion chamber from cycle to cycle, it changes the expansion ratio, and therefore its power.

Do you add oil to a hot or cold engine?
You can put oil in your car when the engine is hot. Check the oil level after the engine has cooled, but it is safe to add oil to your car if it is warm or slightly hot, provided it has been turned off for several minutes. Be sure to avoid overfilling the oil past the “max” line on the dipstick.
How much carbon in gasoline is consumed by the engine?
