The paper describes the solution of the problem of determining the relationship of the main design parameters of the motion conversion mechanism with the design and technical parameters of a crankless reciprocating machine (engine) and identifying the influence of these parameters on the machine performance, as well as the value of the developed torque on the output shaft as compared to the crank-rocker internal combustion engine. The comparison is made based on the similarity (identity of the parameters characterizing the conditions for the implementation of the working cycle of a heat engine) of the working processes flowing in a cylinder of a crankless machine and a crank-rocker engine. A conclusion is made on the advantage of the crankless machine concerning the design of high-torque engines. Practical recommendations are given on the choice of design parameters depending on the technical requirements, the purpose, and sphere of application of the crankless machine.
