As you may know, an engine's compression ratio is directly linked to its combustion efficiency. All else being equal, higher-compression engines tend to make more power while offering better fuel ...

"Too little compression will usually result in unmet performance expectations. On the high side [too much compression] carries greater risk in tuning and potential component failure if appropriately ...

Compression: An automotive term used by everybody, forever. Let's get into some detail and maybe develop a better understanding. Pressure, and more pressure: It's a must-have to produce power within ...

Pretty simple question actually (or so my ignorant mind thinks): At what compression ratio would an engine benefit from higher octane fuel? The Focus I drive is just over 10:1, and I've heard some say ...

What is compression ratio? An explanation of compression ratio; what it means and why it is important. Why some cars need ...

When comparing engine specs for nearly any combustion engine automobile, we see a number of variations available with differing outputs of horsepower and torque. We often have a choice of gasoline or ...
