Problems solved by technology

These substances will cause harm to human health and the environment. In order to improve the quality of fuel and improve its performance, many fuel additives have appeared on the market for gasoline. Combustion-supporting effect, some provide oxygen-enriched components to fully burn fuel, etc., all perform well in a single aspect, but the overall performance is average
[0003] For example, the application number is a fuel additive of 200810072498.7, which is composed of dialkyl carbonate with general formula R1OCOOR2, biscyclopentadienyl iron, benzotriazole, fatty alcohol and ethylene oxide condensate, Alkylphenol and ethylene oxide condensate, although it considers the oxygen-rich components and combustion-supporting effect, it is not good in oxidation resistance and gasoline cleansing and dispersibility. In addition, dicyclopentadienyl iron, and manganese agent, Like lead agent, because the combustion emissions will be deposited on the surface of the combustion chamber, intake valve and spark plug, it will affect the normal operation of the engine and damage the exhaust after-treatment system over time. Now the new "Automotive Gasoline" standard also includes It is stipulated that lead and iron additives shall not be artificially added

Abstract

The invention discloses a high-clean gasoline additive and a preparation method thereof, which are prepared from the following raw materials in weight percent: DMC, n-pentanol, N,N'-di-sec-butyl-p-phenylenediamine, benzotriazole, Sorbitan monooleate, polyisobutylene urethane and special-effect catalyst, the raw materials of which contain oxygen-rich and multi-effect ingredients, have good compatibility with gasoline, and comprehensively improve the physical and chemical performance indicators of oil products; this product can significantly Improve the octane number of gasoline and have excellent anti-knock effect, have a good cleaning effect on gasoline and make it fully combustible, thereby improving the thermal efficiency of fuel and the power per liter of the engine; this product significantly reduces the harmful gas emitted by the tail gas, Environmental pollution is reduced.

Description

technical field [0001] The invention belongs to the field of fuel additives, in particular to a high-clean gasoline additive and a preparation method thereof Background technique [0002] While automobiles bring comfort and convenience to our lives, they also cause certain pollution to the natural environment. As we all know, during the combustion process of automobile fuel, some harmful automobile exhaust will be emitted through the exhaust pipe of the automobile. These Exhaust gas includes CO, incompletely burned hydrocarbons HC, NO x and particulate matter PM etc. These substances will cause harm to human health and the environment. In order to improve the quality of fuel and improve its performance, many fuel additives have appeared on the market for gasoline. Combustion-supporting effect, some provide oxygen-enriched components to fully burn fuel, etc., all perform well in a single aspect, but the overall performance is average. [0003] For example, the application ...
