Abstract

U ovom radu analizira se sustav za direktno ubrizgavanje goriva kod Diesel motora. Prvo de se analizirati princip rada četverotaktnog Diesel motora, navest de se taktovi te zbivanja koja su povezana sa svakim taktom. Nakon toga analizira se sustav za ubrizgavanje goriva. Sustav je u radu podijeljen na podsustave niskog i visokog pritiska te se navode i analiziraju pojedini dijelovi svakog podsustava. Potom se analizira električno upravljačko računalo koje upravlja radom cijelog sustava za ubrizgavanje goriva. Pri samom završetku ovog rada navode se i analiziraju različiti sustavi za ubrizgavanje goriva poput zastarjele mehaničke visokotlačne pumpe pa do električki reguliranih pumpi s aksijalnim ili radijalnim klipovima zaključno s modernim Common Rail sustavom koji daje najbolje karakteristike.

Abstract (english)

In this paper direct Diesel injection system will be analized. Firstly engine working principle will be explained aswell as actions and changes linked with each stroke. Afterwards, injection system will be analized. In this paper it will be split into low and high pressure subsystems. Then electric control computer which controls the operation of the whole system will be analized. At the end of this paper various injection systems will be analized, like old mechanical high pressure pump, electrically regulated pumps with axial or radial pistons, finalizing with Common Rail system which is proven to have the best characteristics.
