Reducing toxic emissions and vibration levels from automobile engines by using gasoline with oxygen-containing additives

This article studies specific methods for reducing harmful gases, noise and vibration levels from gasoline light-duty vehicles. For this purpose, scientific research on the rational selection of the composition of complex oxygenated additives in gasoline and the efficiency of vehicle operation on this fuel was studied. Also, changes in the operational performance of light-duty vehicles as a result of the selection and use of the concentration of complex oxygenated gasoline were determined based on the results of experimental research. The use of oxygenated gasoline with a complex composition in automobiles compared to the base gasoline – AI-92, has resulted in a reduction in exhaust gas emissions by CO – 28-36 %, CH – 13-32 %, NOx – 47-49 %, CO 2 – 70-81 %, and a reduction in noise level by 4-6 dB due to reduced detonation.
