EFFECTS OF ENHANCER DIESEL FUEL AND VIBRATING WINGS SUBSOILER PLOW ON THE PERFORMANCE OF AN AGRICULTURAL TRACTOR
The aim of the study was to investigate the fuel consumption, depth stability ratio, noise, driver seat vibration of agricultural tractors (DSV), and slippage during tractor operation by using a kind of fuel (enhancer and non-enhancer fuel), vibration and non-vibration wings of subsoiler and engine speeds. Three engine speeds that include 1000, 1500 and 2000 rpm were considered. The results indicated significant positive data for all traits under enhancer fuel compared with non-enhancer and studies treatments. The experiment was analyzed as a three-factor factorial experiment using a split-split plot- Randomized Complete Block Design. Duncan's multiple range test used to test for significance. The results showed positive superiority of enhancer fuel in the fuel consumption, depth stability ratio, noise, DSV, and slippage, while achieving a negative increase in DSV, noise, and slippage with wing vibration of subsoiler. However, the DSV for wing vibration of subsoiler remained within European Parliament and Council Directive 2002/44/EC (OJ, 2002) and the measurements previously approved from ISO 2631-5 (2004). Besides, increasing the engine speeds leads to an increase in noise, DSV, and slippage, while at 2000 rpm speed of the engine was recorded as the lowest value of 11.905 L. ha-1 for fuel consumption, respectively. Finally, the results indicate the superiority of enhancer fuel and vibration wings at all engine tractor speeds to register less fuel consumption, DSV and slipping lead to the conclusion that adding enhancer fuel improved the performance of the agricultural tractor.
