Abstract

Based on the analysis of the conditions for the implementation of the working cycle in the
combustion chamber of a heat engine (internal combustion engine) of a new scheme, the article
proposes a comprehensive analytical description of the processes that make up its working cycle.
Briefly analyzed are the basic structural schemes of new heat engines with a mechanism for converting the reciprocating motion of their pistons into a rotational cargo shaft. Based on the equations of thermodynamics, mechanics, and the theory of internal combustion engines using the
Heaviside step function, a system of equations is formed that describes the nature of the flow of
parameters and cycle indicators under conditions of using a heat engine at full (and close to) load
conditions. In relation to a specific scheme of a crankless piston machine (engine), examples of
numerical evaluation of the parameters and indicators of the duty cycle of such a heat engine are
given. It is shown that under similar conditions for the implementation of the duty cycle in a
crankless piston machine (engine) and an engine with a crank mechanism, in a crankless engine
(with a two-period treadmill), the same power value is realized at rotational speeds two times
lower than in internal engines combustion with a crank mechanism. A recommendation is made
about the possibility and expediency of using crankless piston machines-engines as sources of
mechanical energy.
