The Effect of Diesel Fuel Additives on the Exhaust Gases of Agricultural Tractors During Plowing

Abstract

Abstract The research aims to study the effect of the fuel type, plow types, and engine speeds on carbon monoxide (CO), hydrogen sulfide (H2S), and oxygen (O2) gases. The field experiments were conducted on an experimental farm in Al-Hamdaniya, Nineveh, Iraq. The investigation was factorial, using a Randomized Complete Block Design with Split –Split plot Design. The three types of fuel were placed in the main plot, the plow types in the secondary split plot, and the speed engine in the Split –Split action. The results showed significant differences between the fuel, plows, and engine speeds in most studied traits. There were no significant differences in the interaction between the plow types and the engine’s speed regarding CO emissions at the two levels. Still, the rate at 1000 rpm recorded the lowest emission value. At the two levels (the level of the exhaust nozzle - the status of the tractor driver’s seat), it amounted to 39.833-18.767 ppm, respectively. Moreover, the highest reading of H2S gas emissions was recorded with diesel without added fuel and the moldboard plow. Finally, the results showed no significant difference, as diesel fuel with super additives from Manol and an engine speed of 2000 rpm recorded the lowest emission rate for the emission rate of O2 gas, amounting to 20.550%.
