A.Here's a pressure-volume diagram for a combustion engine. Although rough, it is an approximation of the so-called air-standard cycle. '' Point (a) is at atmospheric pressure, after which the air is ...

In the case of the internal-combustion engine, where virtually every separate portion of explosive mixture behaves differently, the usual thermodynamic interpretations of the pressure-volume indicator ...

Screw blowers use internal compression, lobed blowers use external compression. Screw blowers are more efficient, potentially cutting energy use in half. Resources: Atlas Copco, www.atlascopco.com ...
