When developing a draft design of a piston engine, it is necessary to carry out a calibration calculation of its main parts. To do this, it is necessary to know how the loads on parts change when the indicators vary according to the external speed characteristic. A technique is proposed for simulating the maximum pressure of a piston engine cycle using an external velocity characteristic at the design stage, when it is impossible to obtain experimental data. For this, dimensionless coordinates are proposed for describing the performance of the engine being designed. The transition to dimensionless indicators allows the use of these prototype engines. The proposed dependences allow one to model an external velocity characteristic, by which one can trace the change in the main parameters of a piston engine. The laws of changes in the average effective and indicator pressures on the external velocity characteristic are analyzed and the law of change in the maximum cycle pressure is proposed based on the change in the dimensionless coordinates.
