Exhaust purifying agent

Abstract

The invention discloses an exhaust purifying agent, which aims to solve the problems that the conventional additive using plenty of aromatic hydrocarbon as a solvent is high in toxicity and seriously pollutes the environment at the same time. The exhaust purifying agent comprises the following components in parts by weight: 50 to 80 parts of cetyl palmitate, 30 to 50 parts of methyl behenate, 5 to 8 parts of stearyl stearate, 2 to 4 parts of dodecyl phenyl amine sulfonate, 1 to 3 parts of octadecyl amine sulfonate, 2 to 5 parts of sulfo-benzene and 1 to 3 parts of pentaerythritol. The prepared purifying agent has a good effect and low toxicity, and can effectively reduce environmental destruction.

Description

technical field

[0001] The invention relates to a tail gas purifying agent. Background technique

[0002] Since the automobile came out, its fuel economy and exhaust gas purification have always been the focus of researchers. For decades, scientists have carried out a lot of work on this topic, and have opened up three technical routes. One is to improve the various parts of the engine, such as improving the atomization characteristics of the carburetor to make it better atomized to increase the combustion surface; improving the ignition time and method to make the combustion more complete; reasonable air-fuel ratio and compression ratio design, etc.; this type of research is the maturity and perfection of the engine; the second is simply to start from the exhaust gas purification, and install a catalyst-containing device at the exhaust pipe to promote the poisonous gases CO, NO in the exhaust gas. x , HC, and organic sulfur are further oxidized, such as CN1070984, CN10...
