Abstract

Smanjenje radnog volumena motora s unutarnjim izgaranjem je u automobilskoj industriji
jedna od glavnih strategija za povećanje učinkovitosti i smanjenje emisija ispušnih plinova.
Ugrađivanjem manjih motora s turbopunjačima i naprednim sustavima ubrizgavanja goriva se
postiže ista ili veća izlazna snaga pri čemu se istovremeno smanjuje potrošnja goriva.
Downsizing nudi brojne prednosti koje imaju veliki utjecaj na ekologiju jer smanjenje emisija
CO₂ i bolja iskoristivost goriva... More pridonose boljem zadovoljavanju ekoloških normi i regulativa
koje s vremenom postaju sve strože. S druge strane postoje i određeni izazovi poput većeg
toplinskog opterećenja, mogućeg smanjenja trajnosti motora i stvara se potreba za složenijim
sustavima hlađenja i podmazivanja. U radu su analizirani tehnički aspekti downsizinga,
utjecaj na performanse i ekološku prihvatljivost te je prikazana usporedba s tradicionalnim
motorima većeg obujma. Kroz analizu je prikazan utjecaj downsizinga na potrošnju goriva,
emisija štetnih plinova i pouzdanost motora tijekom eksploatacije. Less

Abstract (english)

Reducing the working volume of internal combustion engines is one of the main strategies for
increasing efficiency and reducing exhaust gas emissions in the automotive industry. By
installing smaller engines with turbochargers and advanced fuel injection systems, the same
or higher power output is achieved while simultaneously reducing fuel consumption.
Downsizing offers numerous advantages that have a great impact on the environment, as the
reduction of CO₂ emissions and... More better fuel efficiency contribute to better compliance with
environmental norms and regulations that are becoming increasingly strict over time. On the
other hand, there are also certain challenges such as higher heat load, possible reduction in
engine durability and the need for more complex cooling and lubrication systems. The paper
analyzes the technical aspects of downsizing, the impact on performance and environmental
friendliness, and presents a comparison with traditional engines of larger volume. The
analysis shows the impact of downsizing on fuel consumption, emission of harmful gases and
reliability of the engine during exploitation. Less
