Problems solved by technology

Such as combustion calorific value, vapor pressure, vapor density, harm to human body and environmental pollution, in short, it does not meet the requirements of vehicles designed according to the characteristics of gasoline. For example, methanol is a polarized organic substance, which will corrode the parts on the vehicle. high degree of aging
The combustion calorific value, boiling point, vapor pressure and vapor density are all lower than those of gasoline, resulting in poor power performance. At the same time, it will also cause poor starting of the vehicle at low temperature and air resistance.
[0003] The United States has done a lot of work on the above problems as early as the 1930s, because the difference in performance between methanol and gasoline does not meet the technical requirements of existing vehicles designed to use gasoline as fuel, so gasoline can only be improved along the requirements of gasoline standards. to adjust the power of a large number of existing vehicles, reduce emissions, and go down the old road

example 1

[0023] This example is the preparation of environmentally friendly additives, the specific preparation process:

[0024] 1. In a sealed environment at normal temperature, use a combined high-speed shearing machine (rotating speed is 2800 rpm) to prepare an emulsified synthetic solution with 60% methanol or fusel alcohol, 20% ethanol and 10% isobutanol, and then add 5% Acetone (CH 3 COCH 3 ) to obtain A-1 solution after stirring for 20min;

[0025] 2. Add 2% hydrogen peroxide to A-1 solution under stirring condition to obtain A-2 solution;

[0026] 3. Under the condition of stirring, add 0.3% SEO-25 emulsifier into the A-2 solution, stir for about 25 minutes until the solution becomes transparent and colorless, slowly add 2.7% gasoline while stirring until it is completely dissolved, And it is a transparent liquid, and its particles are all below 0.06 microns, and it becomes a multi-phase dispersion, which is an environmentally friendly gasoline additive product.

example 2

[0028] This example is to prepare the additive of the present invention, specific raw material amount: methanol 42%, ethanol 35%, isobutanol 15%, acetone 5%, hydrogen peroxide 1.5%, SEO-25 emulsifier 0.5%, unleaded gasoline 1.0%.

[0029] Preparation method is the same as example 1.

example 3

[0031] This example is the concrete application of the additive product that example 1 makes.

[0032] Add 30% example 1 additive product of gasoline weight in No. 90 unleaded gasoline, stir evenly.

[0033] Tested by the Product Quality Supervision and Inspection Center, its physical and chemical properties are shown in Table 1. It can be seen from the data in Table 1 that the gasoline octane number increases by 4 units.

[0034] At idle speed, CO is 28% lower than No. 90 gasoline, and HC is 20% lower; when the engine is accelerated to 3000 rpm, CO can be reduced by 99.9%, and HC can be reduced by 54%. Such a result is quite impressive, and it can be called environmentally friendly gasoline. The above results are the average of 5 times of testing at Kunming Ninth Testing Station and before and after the vehicle repair shop.

[0035] Test items

[0036] Note: The inspection basis is GB17930-1999 "Unleaded Gasoline for Vehicles"

Abstract

The environment protecting gasoline additive is one kind of transparent liquid product prepared with the materials including methanol, ethanol, isobutanol, acetone, hydrogen peroxide solution, emulsifier and small amount of gasoline and through several times of mixing. It is added into gasoline to lower pollution greately, raise gasoline grade, reduce consumption of petroleum, with the added amount being 2 / 3 of gasoline.

Description

technical field [0001] The invention relates to an additive for engine fuel, more precisely, it is an environment-friendly gasoline additive which can significantly reduce CO and HC compounds in the tail gas emitted by vehicles. Background technique [0002] In order to improve the performance of gasoline, adding additives to gasoline is one of the cost-effective means. There are many types of fuel additives on the market, such as adding antioxidants and metal deactivators to improve the storage stability of gasoline, but some additives contain certain metals and aromatics. Although they increase the fuel combustion value, they do not Pollutants emitted after combustion increase secondary pollution. With the requirements of economic development and environmental protection, how to reduce the consumption of natural resources, save energy and reduce exhaust emissions has become an important issue of human concern. In recent years, some domestic units have studied the use of ...
