What is Otto Cycle – Problem with Solution – Definition

WebIsochoric processes are those that occur with a constant volume. If volume is unable to change, no work can be performed on the system. By process of elimination, any change in the energy of a system must be due to heat added to or released from the system. On a PV curve, since volume is a constant, these processes are represented by a vertical ... WebIn this example, let assume an Otto cycle with a compression ratio of CR = 9 : 1.
