Improving efficiency of internal combustion engine: Perspectives of application free piston engine in agricultural engineering

Abstract

The article discusses various schematic diagrams of a reciprocating internal combustion engine (ICE) and shows their main disadvantages, in particular, low efficiency, which, depending on the type of modern ICE, ranges from 0.25 to 0.5. To increase this indicator, the search for more advanced ICE schemes continues. For this purpose, a new schematic diagram of a free-piston internal combustion engine (FPICE) is proposed, in which power is transferred by a hydraulic drive, as a result, the efficiency increases from 30 to 40%.
