Problems solved by technology

[0003] In order to control the harm of automobile exhaust emissions to the environment and human beings, many countries in the world have formulated increasingly strict regulations on automobile exhaust emissions. It is effective to install three-effect purifiers and EFI closed-loop controllers on the exhaust system of automobile exhaust. One of the measures to solve automobile exhaust pollution, but most of this kind of equipment can only purify granular media, and the purification effect on carbon monoxide and hydrocarbon gases is relatively small, and cannot achieve good purification effect

Abstract

The invention relates to the technical field of automobile exhaust pollution control, especially an automobile exhaust detergent and a preparation method thereof. The automobile exhaust detergent is prepared by nitric acid propyl acetate, N, N-dimethylacetylamide, ethylene glycol monomethyl ether, diisopropyl ether, fatty alcohol, lauryl alcohol, high-carbon number fatty alcohol, multiple crude alcohol, glycerol palm kernel fatty acid ester and blackKwai acid glycerol according to a certain weight ratio. The invention has simple principle, easy preparation and low production cost, which can effectively purify exhaust gas discharged by vehicle and can help protect the environment; the pollution is reduced; the invention is suitable for wide promotion and application.

Description

(1) Technical field [0001] The invention relates to the technical field of automobile exhaust pollution control, in particular to an automobile exhaust cleaner and a preparation method thereof. (2) Background technology [0002] At present, the engine exhaust gas of almost all fuel vehicles is directly discharged into the air through the exhaust pipe. These exhaust gases contain a large amount of harmful gases such as sulfides, nitrogen compounds, carbon, and lead, and inhalable particulate matter. These exhaust emissions are distributed in the The air is permeated, and the concentration of harmful gases and floating dust in the air and the proportion of days in smog days are constantly increasing, which is increasingly polluting the living environment of human beings and threatening human health. [0003] In order to control the harm of automobile exhaust emissions to the environment and human beings, many countries in the world have formulated increasingly strict regul...
