The capacity of a compressor can be affected by a refrigeration system’s ever-changing pressures. In addition, suction pressure entering the compressor will change the density of the suction gasses ...

High-output engines live in a world of brutal cylinder pressures, extreme temperatures and razor-thin safety margins, and the humble piston sits at the center of that storm. When power levels climb, ...

My Jan. 8 column covered refrigerant gas density coming into a compressor’s cylinder from the suction line and how it is affected by temperature. That column also covered how refrigerant density ...

Low- And High-Compression Fuel Economy Engines: The Techniques Are About The Same, But The Approach To Each Is Somewhat Different. A.Most stock cylinder heads have factory-cut undercuts of the type ...

The folks at TRW have come up with a revolutionary idea for reducing the piston ring drag of the top compression ring. It is called the Pressure Balance Ring (PBR). Essentially, the PBR design amounts ...
