At first glance, the concept of engine compression is simple enough:It's the ratio of the volume of the combustion chamber and bore when thepiston is at bottom dead center (BDC) versus when it is at ...

Assuming a properly tuned engine, there are three factors that contribute to poor streetability: long cam duration, high compression ratios, and excessive cruise rpm. Since cam selection is largely ...

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 ...

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 ...

While we like to think of 2002 as being part of a high-tech age, our beloved internal combustion engine hasn't really changed much in the last 50 years. We're still using pushrods and overhead valves, ...

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 ...
