Fuel line combustion promotor with isopentane emission reduction function as well as preparation and use methods

Abstract

The invention discloses a fuel line combustion promotor with an isopentane emission reduction function as well as preparation and use methods. The fuel line combustion promotor comprises an active additive, wherein the active additive is prepared from components in parts by weight as follows: 47-75 parts of SiO2, 20-45 parts of CaCO3, 12-15 parts of Al2O3, 0.1-2.5 parts of TiO2, 3.0-10 parts of Fe2O3, 0.05-0.5 parts of MnO, 1-4.5 parts of MgO and 0.05-0.5 parts of rare earth elements. Compared with the preparation method in the prior art, the fuel line combustion promotor as well as the preparation and use methods has the following beneficial effects: in terms of the use way of the product, the fuel line combustion promotor is mounted on a fuel line in an engine compartment, obvious effectcan be tested when a vehicle travels for about 50-200 km, and content of isopentane in tail gas is reduced by about 30%. The effect is stable after the vehicle travels for about 500-1000 KM, contentof isopentane is reduced by about 60-80%, and lasting and stable effects can be realized when a refit vehicle travels for 1000-3000 km.

Description

technical field [0001] The invention relates to the technical field of fuel additives, in particular to a gasoline pipeline burner for reducing the emission of isopentane, a preparation method and a use method. Background technique [0002] A large number of test data over the years have found that the exhaust gas of gasoline vehicles contains a considerable proportion of isopentane, and isopentane is one of the main components of gasoline, and is not a product of combustion, that is, gasoline has not been completely burned. [0003] In order to improve the combustion efficiency of automobiles, although the gasoline engine technology has made great progress, there are still defects and deficiencies in the prior art: 1. In order to make the gasoline fully burnt, the gasoline engine factory uses a large amount of fuel to improve the combustion efficiency of the automobile engine. New technologies, such as multi-valve, in-cylinder direct injection, multi-point ignition, three-w...

Problems solved by technology

[0003] In order to improve the combustion efficiency of automobiles, although the gasoline engine technology has made great progress, there are still defects and deficiencies in the prior art: 1. In order to make the gasoline fully burnt, the gasoline engine factory uses a large amount of fuel to improve the combustion efficiency of the automobile engine. New technologies, such as multi-valve, in-cylinder direct injection, multi-point ignition, three-way catalysis, etc., but still contain a considerable proportion (usually about 8-9.5% of the total organic HC) of unburned components in the exhaust gas. directly into the atmosphere; 2. Many manufacturers have developed gasoline additives and products with energy-saving functions, but some of them need to be added repeatedly, and some have no obvious effect or even the opposite, while the products for the full combustion of isopentane are currently No;
