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 ...

A lot of talk is taking place behind-the-scenes with concerns that Mercedes and Red Bull have found a loophole in the FIA regulations.

Compression Ratio = Absolute discharge pressure/Absolute suction pressure Most technicians realize their service gauges read zero when not connected to a system, even though there is a pressure of ...

NYK will install a variable compression ratio system (VCR system) on two large LNG-fueled coal carriers to be built at Oshima Shipbuilding. The vessels are scheduled to be delivered by the end of 2025 ...

While the fashion in high-tech automotive developments might lean towards hybrids and electric vehicles at the moment, there’s still plenty of scope to improve the good old internal combustion engine ...
