Horák, TomášČerňan, Jozef2022-10-282022-10-282022http://drepo.uniza.sk/xmlui/handle/hdluniza/778The paper deals with the specific modification of the M60 two-stroke engine so that the engine can be used in aerobatic conditions. In the introduction of the paper, the basic theory concerning piston two-stroke engines, the principle of operation of this engine, and the analysis of individual fuel systems is first discussed, with a focus on fuel injection systems and their components. Furthermore, the preparation of the fuel mixture is characterized together with the factors affecting it and also the basic characteristics of the engine control unit. In this way, the reader will gain the knowledge necessary for a better understanding of the following chapters. The motivation is to find a way to modify the non-aerobatic engine for the needs of aerobatic flight, and this modification includes a number of important advantages over the original fuel system design mentioned in the paper. At the core of the paper, we discuss the design of the fuel system, including important modifications, and also the practical implementation of this fuel system on the engine mentioned above. At the end of the paper, we evaluate the results of the work achieved by changing and modifying the fuel system on the M60 engine, including the achievement of the set objectives.enPiston engineCarburettorDirect injectionIndirect injectionMixture preparationTwo-stroke engineIntake manifold, Fuel systemConference paperhttps://doi.org/10.26552/pas.Z.2022.2.12
