Lubják, PeterČerňan, Jozef2022-08-182022-08-182022http://drepo.uniza.sk/handle/hdluniza/738The goal of modern society is to improve efficiency in all areas. Our goal is to convert the old engine parts into a functional power unit that is more efficient than the donor parts. Modern electric motors with high efficiency are our main competitors, but our motor has an advantage in a simple design that is easily serviced. We achieve low weight by using lightweight aluminum air-cooled cylinders. In my work, I deal with the fundamentals of two- and four-stroke internal combustion engines. The importance of primary and secondary forces caused by the movement of the crankshaft and pistons is also discussed. Of course, we'll go over how to fill the engine while it's running (carburetor/injection). Following that, I'd like to go over the overall functionality of the drive unit as well as the significance of specific components. In practice, we concentrate on simulating our experimental engine. The purpose of this entire article is to provide the foundational documentation for the subsequent construction of this power unit.enhttp://creativecommons.org/licenses/by/4.0/Trabant radial engineTrabant three-cylinder engineTrabant aircraft engineConference paperhttps://doi.org/10.26552/pas.Z.2022.1.15
