Problems solved by technology

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 and in particular discloses an automobile exhaust cleaning agent. The automobile exhaust cleaning agent is preparedfrom ethyl propyl nitrate, N,N-dimethyl-acetamide, ethylene glycol monomethyl ether, diisopropyl ether, fatty alcohol, laurinol, high carbon number fatty alcohol, coarse polyhydric alcohols, glycerinpalm kernel fatty acid ester and glycerin aconitate according to a certain weight ratio. The automobile exhaust cleaning agent disclosed by the invention is readily available in raw materials, simplein preparation, low in production cost and capable of effectively purifying automobile exhaust, contributes to protecting the environment and reducing pollution and is suitable for wide popularization and application.

Description

technical field [0001] The invention relates to the technical field of automobile exhaust pollution control, in particular to an automobile exhaust cleaning agent. Background technique [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. 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 ef...
