Automobile exhaust cleaning agent and preparation method t hereof

The invention discloses an automobile exhaust cleaning agent and a preparation method thereof. The automobile exhaust cleaning agent is prepared from the following raw materials in parts by weight: 35to 45 parts of methanol, 10 to 12.5 parts of ethanol, 10 to 20 parts of aviation kerosene, 12 to 20 parts of ethyl acetate, 0.04 to 0.08 part of benzotriazole, 10 to 20 parts of naphtha, 5 to 10 parts of methyl tertiary butyl ether, 0.04 to 0.08 part of an antioxidant and 0.04 to 0.08 part of imidazoline oleate. The automobile exhaust cleaning agent disclosed by the invention has the advantages that raw materials which are rich in source, stable in performance and clean in emission after combustion are adopted, a blending technology is simple, the product cost is low, and a production processhas no emission of three wastes; by utilizing the characteristic that alcohol molecules contain oxygen, a combustion ratio of fuel oil is increased, emissions of CH and CO are reduced, and a better protection function on all
