Engines are nowadays mandatory for the domestic as for the industrial use. However, they need enough control and maintenance in order to make their usefulness last longer. Some works have been done for this purpose but they all propose mechanisms and methods that consume a big amount of useful energy from the engine and thus stops it from being operational during the control, and thus, these studies can’t allow to test continuously the operation of the used engine. Other works propose thermodynamic experiments that are too expensive and difficult to be done in order to provide the characteristics of engines. However, the equations of real gases can only be approximate and the studied gases can’t be considered ideal gases at the high pressures inside engines. This paper proposes new accurate formulas and methods to detect cylinders problems by allowing a continuous control of each cylinder brake work without consuming any energy from the operating engine. This work proposes also a new mechanism to measure the availability of each cylinder of the studied engine and thus introduces a new method to test the second law efficiency for the engine. This work explains also and proves all the formulas and methods after a modeling of the connecting rod and crankshaft operation. Consequently, this is a very useful work for the simulations of engine experts as for the simple understanding of beginners.
