The ideal Otto cycle is an example of an isochoric process when it is assumed that the burning of the gasoline-air mixture in an internal combustion engine car is instantaneous. There is an increase in the temperature and the pressure of the gas inside the cylinder while the volume remains the same.
The Otto Cycle is an example of a reversible thermodynamic cycle. ... e.g., isochoric expansion (process 1-2) occurs with some actual volume change. ...
In this process 1–2 the piston does work on the gas and in process 3–4 the gas does work on the piston during those isentropic compression and expansion processes, respectively. Processes 2–3 and 4–1 are isochoric processes; heat is transferred into the system from 2—3 and out of the system from 4–1 but no work is done on the system ...

According to the first section above, an heating for a solid can not be a isochoric, so the pressure change in a non-isochoric heating process is not exactly the thermal pressure. When a solid is loaded with a pressure gauge, and heated/compressed together at high P - T , the thermal pressure of the solid does not equal that of its gauge.
As defined earlier, an incompressible (isochoric) flow is the one in which = This is equivalent to saying that = + = i.e. the material derivative of the density is zero. Thus if one follows a material element, its mass density remains constant.
Another important kind of work is isochoric work, i.e., work that involves no eventual overall change of volume of the system between the initial and the final states of the process. Examples are friction on the surface of the system as in Rumford's experiment; shaft work such as in Joule's experiments; stirring of the system by a magnetic ...
During the constant volume (green, isochoric) process, some of the energy flows out of the system as heat through the right depressurizing process . The work that leaves the system is equal to the work that enters the system plus the difference between the heat added to the system and the heat that leaves the system; in other words, net gain of ...
