Thermodynamic Cycles of Reciprocating and Rotary Engines
... p = p(ϕ ) , where ϕ is the crankshaft rotation angle, using relationship V = V(ϕ ) , which is known from the kinematic analysis, we obtain the developed indicatory diagram.

16. The First Law of Thermodynamics
... This is the 1st Law of Thermodynamics, which states that the internal energy of a system can change in two ways: (1) Heat Q can flow into the system from the surroundings, in which case the internal energy of the system increases. (2) Additionally, work W can be done by the gas system on the surroun ...

15-6 Thermodynamic Cycles
... Many devices, such as car engines and refrigerators, involve taking a thermodynamic system through a series of processes before returning the system to its initial state. Such a cycle allows the system to do work (e.g., to move a car) or to have work done on it so the system can do something useful ...
