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 ...

The temperature of the refrigerant entering the compressor’s cylinder also has an effect on capacity, but for this article, we’ll focus on pressures. COMPRESSION RATIOS Both the high- and low-side ...

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 ...

Last month’s article examined two systems that were experiencing high compressor discharge temperatures. One system had too much refrigerant, while the other had a partially restricted liquid line. In ...
