Thesis abstract (LT)
Baigiamajame bakalauro darbe analizuojamas automobilio „Audi A3“ variklio galios didinimas. Pagrindžiamas variklio prototipo ir galios didinimo būdo parinkimas, skiriamas dėmesys kokie yra variklio galios didinimo būdai. Atlikti variklio šiluminiai skaičiavimai, įvertinti indikatoriniai ir efektyvieji rodikliai, sukimosi dažnio charakteristikos, pagrindinių detalių stipruminiai bei šilumos balanso skaičiavimai. Darbe pateikiami techniniai brėžiniai ir išvados, pagrindžiančios variklio galios didinimo efektyvumą.
Darbą sudaro 10 dalių: įvadas, variklio prototipo pagrindimas, variklio galios didinimo būdai, šiluminiai skaičiavimai, indikatorinės diagramos, rodiklių skaičiavimas, detalių skaičiavimas, išvados, literatūros sąrašas, priedai.
Darbo apimtis 63 p. teksto be priedų, 21 iliustr., 16 lent., 20 bibliografinių šaltinių.
Atskirai pridedami darbo priedai.

Thesis abstract (EN)
The bachelor’s thesis analyzes the power enhancement of the Audi A3 engine. It provides justification for the selection of the engine prototype and the power increase method, focusing on various techniques for enhancing engine performance. The study includes thermal calculations of the engine, evaluation of indicative and effective parameters, rotational frequency characteristics, as well as strength and heat balance calculations of the main components. The thesis presents technical drawings and conclusions supporting the effectiveness of the engine power increase.
The thesis consists of the following sections: introduction, justification of the engine prototype, engine power increase methods, thermal calculations, indicator diagrams, performance parameter calculation, component calculations, conclusions and recommendations, and a list of references.
The scope of the thesis includes 63 pages of text excluding appendices, 21 illustrations, 16 tables, and 20 bibliographic sources.
