No this is not a Carnot engine because the Carnot engines PV diagram consists of two 0000050770 00000 n Relate the terms isothermal, isochoric, isobaric and adiabatic to various thermodynamic processes, and how to move your thermodynamic system through these processes. 0000047849 00000 n 0000070594 00000 n <<21D8DC5A88FAC243AF0E4161AFBC501C>]>> 0000002825 00000 n The electric work output of the engine was easily determined by the electric generator which is connected to the combustion engine. nQt}MA0alSx k&^>0|>_',G!
