Gasoline additive for purifying tail gas

Abstract

The invention relates to an additive for gasoline, in particular to an additive for gasoline, which can purify the tail gas discharged by a vehicle using the gasoline after being added into the gasoline and can also be used for directly replacing fuel. The additive of the invention contains methanol or ethanol, isopropanol, isobutanol, xylene, toluene, hydrogenated naphtha, isobutane, methyl tertiary butyl ether, benzyl alcohol, isopropylamine, isooctane, methyl isobutyl ketone and isohexane, wherein the weight ratio of the alcohols of the methanol or the ethanol, the isopropanol and the isobutanol accounts for 47%-55%, the weight ratio of the xylene and the toluene accounts for 19%-31%, and the weight ratio of the hydrogenated naphtha, the isobutane, the methyl tertiary butyl ether, the benzyl alcohol, the isopropylamine, the isooctane, the methyl isobutyl ketone and the isohexane accounts for 16%-23%. The invention has the advantages that after the additive is used, the content of the harmful gas in the tail gas of vehicles can be lowered, and the air pollution can be reduced, thereby reducing the damage of the tail gas of vehicles to the ozonosphere in the atmosphere and reducing the conditions of causing global warming.

Description

technical field [0001] The invention relates to an additive for gasoline, in particular to an additive for gasoline that can purify the tail gas emitted by vehicles using the gasoline after being added to gasoline, and can also be used as a direct substitute for fuel. Background technique [0002] Gasoline currently used in automobiles contains CO and SO in the exhaust gas emitted by automobiles during combustion 2 , NO X etc. are the root causes of air pollution. In order to improve the quality of gasoline, many companies have invested a lot in research. Up to now, although they have proposed additives such as alcohol and hydrogen, they have not yet entered the practical stage due to the following technical problems. [0003] 1. The existing gasoline additives do not conform to the current air mixing ratio of automobile engines and must be adjusted before use. [0004] 2. When using existing gasoline additives, due to excessive heat, knocking (abnormal explosion) is like...

Problems solved by technology

[0003] 1. The existing gasoline additives do not conform to the current air mixing ratio of automobile engines and must be adjusted before use

[0004] 2. When using the existing gasoline additives, due to the high heat, knocking (abnormal explosion) phenomenon is easy to occur, and it may cause considerable damage to the seal or mechanical parts of the internal combustion engine
