description: In this work, a computational study was carried out to create a small-capacity engine with supercharging from a reciprocating compressor. The expediency of using a positive displacement compressor as the most suitable for ensuring the coordinated operation of a combined piston engine and compressor at high efficiency is analyzed. The working process in three operating modes, effective indicators and engine toxicity indicators calculation was carried out using the RP2018 program. The engine joint operation and the reciprocating compressor as a supercharger analysis was made. For this, the dependences of air consumption on the crankshaft speed and boost pressure are determined, which are necessary to achieve the designed effective power engine according to the hydraulic characteristics of the prototype under study, which was chosen as a four-cylinder four-stroke atmospheric engine. As a result, the specified engine parameters were achieved with a decrease in the number of working cylinders and their replacement with piston compressor cylinders. The main harmful emissions with exhaust gases reduction such as NOx, CO and CO2 has been achieved. Based on analytical calculations, possible engine layouts were developed with the replacement of one or two working cylinders with a reciprocating compressor, as well as the engine longitudinal and transverse sections.
