Determination of operational parameters for Belarus 922 tractor running on mixed fuel

Introduction. The paper explores an impact of mixed fuel on the performance of the tractor in the process of agricultural work. The aim of the study is to obtain quantitative indicators of Belarus 922 tractor. The mixed fuel consists of diesel and rapeseed oil. Materials and Methods. The operational research of the tractor with the installed set of instruments and equipment was carried out in the conditions of agricultural production. Results. We obtained quantitative performance of Belarus 922 tractor running on pure diesel oil and on mixed fuel consisting of 60 % diesel and 40 % of rapeseed oil in plowing the soil and in processing before sowing. The analysis of the data showed a change in the specific performance indicators of the tractor running on the mixed and diesel fuel during agricultural processing. When plowing G value increased from 11.86 to 12.54 kg/ha, the amount of NOx increased from 344.4 to 373.2 g/ha, CO value increased from 136.9 to 137.1 g/ha, C value; decreased from 11.2 to 8.04 g/ha. When processing the soil before sowing G,^ value increased from 4.61 to 4.86 kg/ha and NOx value from 137,9 g/ha to 151 g/ha, CO value decreased from 60.7 to 45.6 g/ha and C value decreased from 6.52 to 4.04 g/h. Conclusions. The test results demonstrate the expediency of using mixed fuel to improve the performance of Belarus 922 tractor in agricultural production.
