In this video, we explore the compression ratio of your engine, covering its definition and significance, as well as how it ...

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 ...

With the combustion chamber being the root of all horsepower, it only makes sense that you start spec'ing an engine build there. One of the key variables in engine building is compression ratio, or ...

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 ...

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 ...
