Abstract

U radu je analiziran uzrok kvara motora EA888/3 oznake DNUC osobnog vozila Golf 7 GTI TCR. U uvodnom dijelu obrađena je teorijska pozadina samog modela motora sa svim potrebnim tehničkim karakteristikama. U eksperimentalnom dijelu rada provedena je analiza kvara i sva potrebna ispitivanja u laboratorijski osiguranim uvjetima.
Rezultati ovog istraživanja doprinose boljem razumijevanju izazova s kojima se
suočavaju sustavi ubrizgavanja goriva i mogu pomoći u razvoju učinkovitijih strategija održavanja, što bi dugoročno moglo rezultirati većom pouzdanošću, manjim troškovima održavanja te produženjem radnog vijeka motora.

Abstract (english)

The paper analyzes the cause of failure in the EA888/3 engine, model code DNUC, from the Golf 7 GTI TCR personal vehicle. The introductory section covers the theoretical background of the engine model, including all relevant technical specifications. In the experimental section, a failure analysis was conducted along with all necessary testing in laboratory – controlled conditions.
The results of this study contribute to a better understanding of the challenges facing fuel injection systems and may assist in the development of more effective maintenance strategies, potentially leading to greater reliability, reduced maintenance costs, and an extended engine lifespan in the long term.
