The Effect of EHR System Setting on Fuel Consumption and Tractor Engine Speed Variation

Abstract

The work is aimed on possibilities of fuel consumption reduction via EHR system setting with the infl uence on tractor engine speed variation. During tractor utilization in agricultural applications fuel consumption is measured and evaluated. The main objective of this text is fuel consumption reduction verifi cation. Firstly, article describes tractor engine parameters acquirement. Complete engine characteristic is obtained from laboratory experiments. This was essential step for lowest fuel consumption area detecting. Next, the principle of EHR system function is clarifi ed. Then connection between complete engine characteristic and EHR system setting interaction is mentioned and the aim of fi eld measurement is set. Another part is devoted to fi eld measurement conditions and EHR system setting. This part is essential for the possibility of fi eld measurement re-examination. Deep plowing with John Deere 6920S and Lemken Vari Diamant 10 was realized. The EHR various settings were examined and their eff ect on tractor engine speed variation was observed. The results show possibility of fuel consumption reduction. The properly chosen aggregation of tractor power and plough type with correct electro-hydraulic system setting brings fuel consumption reduction. This conclusion may be used for fuel savings in global scale for better economic utilization of tractor.
