“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 ...

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 ...

Stock car racing engines are all about efficiency. That's because all the simple solutions for making power have either been maximized or eliminated by the rule book. You aren't allowed power adders ...

You've heard the term compression ratio before, but have you ever wondered exactly what it means? Well, it's time to explain exactly what compression ratio is, and why every carmaker is now obsessed ...

You might have heard about high compression ratios, but what exactly are they, and what kind of effect do they have on an engine's fuel efficiency?

A refrigeration system’s compression or pressure ratio is defined as the absolute discharge pressure divided by the absolute suction pressure. Calculating this ratio can be a big help when it comes to ...

Now that we know how to calculate a compression ratio, let’s dig a bit deeper into what compression ratio physically means when applied to a cooling system. In reciprocating compressors, there must be ...

Engine compression ratios have become a hot topic ...
