Abstract

U ovom radu analiziran je sustav za podmazivanje četverotaktnih motora te njegovi glavni dijelovi. Podmazivanje motora jedna je od najvažnijih komponenti za siguran i stabilan rad motora. Bez sustava za podmazivanje motori bi imali jako mali vijek trajanja te ne bi bili isplativi za daljnju eksploataciju. Opisana je konstrukcija četverotaktnog motora, te princip rada Otto i Diesel motora. Također, nabrojeni su i opisani elementi sustava za podmazivanje. Analizirana su razna ulja prema vrstama i značajkama te su opisane podjele ulja prema određenim parametrima. Na kraju su opisane situacije koje se dogode ako se zanemari zamjena ulja, kako se kontrolira razina ulja te potrošnja ulja na specifičnim dijelovima motora. Osim prethodno navedenoga analiziran je i stupanj degradacije motornih ulja.

Abstract (english)

In this paper, the lubrication system for four-stroke engines and its main parts are analyzed. Engine lubrication is one of the most important components for safe and stable engine operation. Without the lubrication system, the engines would have a very short service life and would not be cost-effective for further operation. The construction of a four-stroke engine and the principle of operation of Otto and Diesel engines are described. Various oils are analyzed according to types and characteristics, and the distribution of oil according to certain parameters is described. Finally, situations are described that occur if oil change is neglected, how to control oil level and oil consumption at specific places in engine. The degree of degradation of motor oils was also analyzed.
