Construction design of a three-cylinder two-stroke radial engine
(University of Zilina, 2022) Lubják, Peter; Čerňan, Jozef
The 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.
Innovation options for selected M60 engine systems: ignition system and engine parameter monitoring
(University of Zilina, 2022) Suchanovský, Matúš; Čerňan, Jozef
The topic of this paper is the possibility of innovating the ignition system of the M60 engine. The main part is the practical solution of the assignment. It shows the condition of the original ignition system, which was innovated in this work. It was a contact ignition system with a fixed advance, using a system of hammers. This solution was replaced by a new type of ignition, specifically an electronic ignition system that allows to change the ignition advance depending on the engine speed and load. The main parts of the new system consist of a control unit and a Hall sensor. It is these two components that make the main difference compared to the original ignition system. We deal with a more detailed description of design, construction and installation in the practical part. We paid attention to the design, the wiring diagram and its installation. At this stage, we addressed the possibilities of fastening a Hall sensor. The use of old components for assembly was not possible, so we proceeded to the design and production of new ones. The innovative ignition system will allow the engine to achieve higher power, lower consumption and the proportion of pollutants in the exhaust gases.
Innovation options for selected systems of M60 engine: exhaust system and engine cooling
(University of Zilina, 2022) Lapínová, Branislava; Čerňan, Jozef
Our article deals with the design and construction of a resonant exhaust system and cooling system for the M60 engine. In introductory part, the article provides the reader with a final overview of two-stroke. In the next chapter, the focus is only on the resonant exhaust system. The article of the reader informs about the basic principles of resonant exhaust systems and points out their fundamental effect on power, torque and fuel consumption. Subsequently, the article gets to the calculation of the resonant exhaust system and its execution. The final chapter deals with the cooling system and solves the design optimization of the shape of deflectors. Both in the previous chapter and in this chapter, it first deals with theoretical knowledge, design and subseguent production of deflectors.
