Gas-reducing inhibitor of methyl gasoline

Abstract

The invention relates to the field of additives of alcohol ether substituted fuel for vehicles, in particular to a gas-reducing inhibitor of methyl gasoline. The gas-reducing inhibitor of methyl gasoline is prepared from 80-90 percent of aliphatic ketones, 4-12 percent of morpholine, 3-8 percent of aliphatic aldehyde and 2-6 percent of aliphatic ether. The compound formulation in the invention hasmore obvious effect than the prior art, has the prominent advantages of interactive effect and complement of each other, effectively inhibits the rise of saturated vapor pressure and reduces the gasresistance of the methyl gasoline. In the invention, the methyl gasoline can reach the national standard by directly adding the gas-reducing inhibitor without regulating the saturated vapor pressure of the base gasoline. The invention has the characteristics of easy production, low cost, favorable effect, high efficiency, convenient use, and the like, and has important practical value for wide promotion of the methyl gasoline.

Description

1. Technical field [0001] The invention belongs to the field of automobile alcohol ether substitute fuel additives, in particular to a methanol gasoline air drag reducing agent. 2. Background technology [0002] With the development of the automobile industry, the demand for fuel oil has risen sharply, especially the lack of oil resources, which has accelerated the research process of alternative fuels for automobiles in various countries. At present, methanol gasoline is the main alternative fuel for automobile engines. Methanol does not contain aromatics or sulfur, which is conducive to preventing air pollution and is beneficial to the environment. However, with the addition of methanol in gasoline, methanol gasoline enters the internal combustion engine in the state of injection during the operation of the car. After parking, due to the high internal temperature, it is difficult to drop down, methanol gasoline evaporates quickly, and a section is formed between the fuel t...

AI Technical Summary

Problems solved by technology

It is very feasible and effective to reduce the saturated vapor pressure of base gasoline and provide room for the addition of methanol. However, there are limitations in the resource limitation of heavy-duty gasoline and the general promotion in regions. In addition, the addition of heavy-duty gasoline has a negative impact on automobile cooling. Starting will be affected to a certain extent; for example, the journal "Automotive Engine" No. 3, June 2008, published "Study on Evaporation and Air Locking Tendency of Methanol Gasoline", the author is Xu Shihai from the School of Logistics Engineering, etc., the article expounds the basic gasoline After adding methanol, the saturated vapor pressure increases significantly, and air lock may occur when used at high temperatures. The reason is that certain components in methanol and gasoline form a low-boiling azeo...
