Additive of automotive liquefied petroleum gas

Abstract

The present invention involves the additive for liquefied petroleum gas for automobiles. It is composed of raw materials with the following weight ratio: at least one oxygen-containing organic solvent 40-60; at least one polymer 5-15; at least one oxygen-containing contentNon-ion surfactants 40-60; at least one antioxidant 5-15.The above-mentioned oxygen-containing organic solvents are selected from nomatum (ethyl) alcohol, MTBE, or di methalin;The antioxidants are selected from 2,2-sub-basis bisphenols or styrerized phenol, etc.;Dilately, such as dilate,; this additive can prevent car nozzles, valve coke, and the valve flap bonding of the valve of the combustion system solenoid valve and gasification evaporator.The Qingjiao was extended from December to more than 6 months; the average of the oil-based Jeta car saved 2-3 liters of fuel 100 kilometers.

Description

technical field [0001] The present invention relates to an additive for liquefied petroleum gas used as automobile fuel, in particular to an additive for liquefied petroleum gas containing a certain amount of olefin used as automobile fuel. Background technique [0002] Many large and medium-sized cities in my country have already used liquefied petroleum gas as vehicle fuel, which has a positive effect on reducing vehicle exhaust pollution and improving urban environmental quality. The use of liquefied petroleum gas as a fuel for automobiles should meet the requirements of automobile driving stability, flexibility, no corrosion to automobile parts, and no wear and tear. The liquefied petroleum gas used for automobiles in foreign countries mainly comes from oil and gas fields. Because it mainly contains saturated C 3 -C 4 Hydrocarbons will not cause problems such as polymerization and coking. my country's liquefied petroleum gas mainly comes f...

AI Technical Summary

Problems solved by technology

[0003] Now there are three ways to solve the above problems, one is to use the alkane gas produced by the oil and gas field, which is of good quality, but the resources are limited; The liquefied petroleum gas with high olefin content produced by other companies can be directly used as automobile fuel, with low cost and close resources. Vehicle power performance decline, etc.

In addition, when liquefied petroleum gas is used, it contains a small amount of tar-like residues, which will cause the solenoid valves in the automotive fuel system and the valve discs of the gasification steamer to bond and fail for a long time.

Especially in winter, it is difficult to start the car, the evaporator is blocked, and the power performance is reduced. It is necessary to clean up the carbon deposits and coke once every 1-2 months, etc., which will affect the normal operation of the car.
