Abstract
Tehničkim preinakama na određenim elementima poboljšavaju se eksploatacijske značajke četverotaktnih motora. Neke od eksploatacijskih značajki koje su opisane u radu su: snaga motora, radni obujam, zakretni moment, potrošnja goriva i potrošnja ulja. Za povećanje učinkovitosti motora i poboljšanje eksploatacijskih značajki razmatrane su preinake na usisnom sustavu, bregastom vratilu, sustavu za rashlađivanje motora te preinake na ispušnom sustavu. Izvođenjem tehničkih preinaka na elementima motora najviše se utječe na snagu motora i potrošnju goriva. Povećanjem snage motora omogućuje se lakše svladavanje otpora koji se javljaju prilikom kretanja vozila što izravno utječe na smanjenje potrošnje goriva. Cilj završnog rada je objasniti kako će i u kojoj mjeri izvođenje određenih tehničkih preinaka utjecati na eksploatacijske značajke četverotaktnih motora. Problem je što se nepravilnom izvedbom preinaka može narušiti ispravnost cjelokupnog sustava. Da bi se ostvario pozitivan učinak na eksploatacijske značajke potrebno je detaljno istražiti utjecaj preinaka određenih elemenata na cjelokupan sustav.

Parallel abstract (English)
Technical modifications on certain elements improve exploitation features of four-stroke engines. Some of the exploitation features described in final work are: horsepower, engine capacity, torque, fuel and oil consumption. To increase engine efficiency and to improve exploitation features the modifications which are considered in final work are modifications on car intake system, camshaft, engine cooling system and modifications on exhaust system. With implementation of technical modifications on engine elements the most impact is on engine horsepower and fuel consumption. Increasing engine horsepower there is much easier to overcome resistance which appear while driving which have direct impact on reducing fuel consumption. The main purpose of final work is to explain how and to what extent will implementation of certain technical modifications affect on exploitation features of fourstroke engines. The main problem is that with irregular implementation of modifications the accuracy of entire system could be disturbed. To achieve positive effect on exploitation features the detailed research of how modifications of certain elements impact on entire system is needed.
