Abstract

U ovom radu su prikazani rezultati istraživanja potrošnje goriva i energije u osnovnim operacijama konvencionalnog sustava obrade tla, oranju i tanjuranju. Istraživanje je provedeno s tri različita traktora na području zapadne Hercegovine na tlu tipa kalkomelanosol. Potrošnja goriva i energije u oranju je mjerena pri dvije različite brzine kretanja i tri različite dubine obrade u oranju, a u tanjuranju pri tri različite brzine kretanja agregata. Povećanje brzine kretanja u oranju i tanjuranju je rezultiralo povećanjem satne potrošnje goriva, ali povećanje učinka je rezultiralo smanjenjem utroška energije po hektaru. Smanjenjem dubine oranja također se smanjila potrošnja goriva. Najmanja potrošnja goriva izmjerena je kod traktora snage 74 kW.

Abstract (english)

This thesis presents the results of research on fuel and energy consumption in the basic operations of conventional soil tillage, ploughing and discharrowing. The research was carried out with three different tractors on the territory of western Herzegovina on the soil type calcomelanosol. The fuel and energy consumption in ploughing was measured at two different speeds and three different depths of ploughing, and at three different speeds in discharrowing. Increasing the speed in ploughing and discharrowing has resulted with an increase in hourly fuel consumption, but the increase in work rate has resulted with reduction in energy consumption per hectare. Reducing the depth of ploughing resulted with reduction of fuel consumption. The lowest fuel consumption was measured for tractor with engine power of 74 kW.
