ABSTRACT
The paper provides a proposal of a quantitative interpretation of operation which (as the operation of Hamilton and
Maupertius presented in classical mechanics and the operation issuing from change of the body momentum) is considered
as a physical quantity with the measurement unit called a joule-second [joule × second]. An original method for
analyzing and estimating the engine operation has been demonstrated in the energetic aspect for the operating needs. The
homogenous Poison process and semi-Markov process have been herein applied to justify the usability of such interpreted
operation. The two processes have made it possible to formulate a model deterioration of the diesel engine operation
over time. Thus, the model is a random Poisson process or semi-Markov process. It has also been shown that the integral
calculus can be (and should be) applied to identify the energetic properties of an engine. Considerations on the energetic
aspect of diesel engine operation are provided on the example of marine engines of a ship’s main propulsion system.
