    Návrh technických úprav pre zvýšenie výkonu piestového motora hercules Teledyne 4A084
    (University of Žilina, 2024) Bernáth, Martin; Čerňan, Jozef
    This article concerns the investigation of the possibilities of increasing the power of the Hercules Teledyne 4A084 engine. The aim of this article is the proposal of technical modifications, that could be carried out on the engine in order to increase its power. In the introduction, the reader is informed about the piston engine in question. The article further takes a look on the effect of individual piston engine systems on performance. In the final part of the work, the ideal air flow through the carburetor for the Hercules engine is calculated, then modifications are proposed, which are expected to increase its performance. The modifications mainly concern the fuel system, the ignition system and the connection of the device for supercharging the engine.

    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.
