Effect of adding diesel fuel improvers and vibration wings of the Subsoiler plow on the noise and vibration of the tractor driver seat
Abstract
The experiment was conducted in the year 2021 – 2022 in one of the fields of the College of Agriculture and Forestry, in the district of Mosul / governorate of Nineveh - Iraq.The topography of the field was characterized by its flatness, and the soil was of a (clay) texture. The research was conducted with the aim of studying the effect ofThree factors to add fuel improved type (diesel smoke stop ) from the German company (LIQUI MOLY) subsoiler plow wing vibration and Three speed for the engine ( 1000 &1500 & 2000) r/min, to know the effect of this on the farm tractor driver’s seat vibration and noise characteristics.Actually experiment was conducted using a ( Randomized Complete Block Design ) and plates system( Split – Split plot design ) On this basis, the experiment was divided into 12 treatments with (3) replications for each treatment and 36 experimental units, and the length of the treatment was (90 meters) and with a constant plowing depth (40 - 45 cm). using Duncan's multiple range test at the 0.05 probability level to test Significant differences between the averages of different treatments .The results indicated that there were significant positive data for all traits, using enhancer fuel compared to without the enhancer.The results showed a significant increase in the vibrations of the driver's seatAgricultural tractor and noise with vibration of the wings of a plow subsoiler. However, the driver's seat vibration values remained for vibration subsoiler plow wings within the directive of the European Parliament and the European Council and the measurements approved by ( ISO 2631-5 in 2004) Besides, increasing engine speeds led to increases noise, and vibrations under the seat of agricultural tractor driver, as well as the results indicate the superiority of the fuel added to it enhancer and vibration wings at all tractor speeds of engine to record the lowest vibration ratios for the agricultural tractor driver's seat. Through the study, it can be concluded that the addition of enhancer to diesel fuel led to improvement tractor performance of agricultural tractor.
