Vliv zatížení motoru JOHN DEERE 8320R na výstupní parametry strojů na zpracování půdy
Liška, Martin
This thesis deals with construction of higher output tractors. The theoretic part is di-vided into three main parts. The first part of this thesis is about emissions of internal combustion engine and element of construction as are compression ignition engine and Common rail fuel injection. The second part is about constructions of undercarriage primarily about front axle of tractor. The last part deals with tractor hydraulic system and its control systems. The practical part of this thesis is about John Deere 8320 R. All measurements have been provided in agriculture operations with machines of Köckerling and Lemken in Zeas Polešovice a. s. The field measurements are divided into two parts of engine work. In the first part of work, the engine has the revolution 1500-1800 min-1, in the second part of work, the engine has the revolution 1800-2100 min-1. Fuel Consumption, total time, revolution, time for rotation, width and depth of the harrow were included. The measured values were calculated effective fuel consumption, opera-tional consumption, efficient performance, operational efficiency and working speed trains.
