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 ...

“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 ...

We might be covering ground that's well trampled for many, but the static compression ratio of an engine is simple to understand: it's all the volume of a cylinder above the compression ring at Bottom ...

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, ...
