Clean motor gasoline

Abstract

The invention discloses clean motor gasoline. The motor gasoline is prepared from the following raw materials in percentage by weight: 2 to 50 percent of methyl acetate, 30 to 95 percent of normal gasoline, 2 to 20 percent of additive A and 1 to 10 percent of additive B, wherein the additive A is one or a combination of more than two of naphtha, petroleum ether and solvent oil; and the additive B is one or a combination of more than two of methyl ten-butyl ether, methylal, cyclopentadiene manganese tricarbonyl, methyl cyclopentadiene manganese tricarbonyl, iso-heptyl ester, tert-butyl ethyl ether, isopropanol, C7 aromatic hydrocarbon, C8 aromatic hydrocarbon and C9 aromatic hydrocarbon. Through detection of authorities, results prove that various indexes of the fuel meet the motor gasoline standard of China, and the fuel has the characteristics of high octane number, high cleanness, low energy consumption and strong power.

Description

technical field [0001] The invention belongs to the technical field of combustion energy, and in particular relates to clean gasoline for vehicles. Background technique [0002] With the development of the automobile industry and the acceleration of the pace of human life, the consumption of gasoline is increasing. However, as a limited resource, gasoline can no longer meet the needs of human beings. The shortage of gasoline resources has become an urgent problem for the development of human society. question. [0003] In order to alleviate the pressure brought by the shortage of gasoline resources to human society, people have to continuously research and discover new energy sources that can replace gasoline. For the automobile industry, the alternative fuels that have been accepted by the market for preparing gasoline mainly include alcohol gasoline and ether gasoline, among which alcohol gasoline mainly includes methanol gasoline and ethanol gasoline, etc., and ether gas...

AI Technical Summary

Problems solved by technology

[0004] Based on the characteristics of low cost, good combustion performance, sufficient raw materials and large production capacity, methanol gasoline has become a petroleum fuel substitute that has attracted much attention. However, due to some physical and chemical characteristics of methanol itself, methanol gasoline has the following disadvantages in the use process: Methanol has poor miscibility with gasoline, the product is easy to delaminate, and has a large colloid content; corrosion of metal parts in automobiles and swelling of rubber and plastic parts; methanol vapor pressure is high, easy to vaporize, and easy to produce air resistance at high temperatures; methanol The latent heat of vaporization is high, and the cold start performance of the car is poor at low temperature; the heating value of methanol is low, and the overall power performance of the product is poor; when the amount of methanol added is high, a special methanol gasoline engine is required

[0006] In summary, the existing gasoline alternative fuels for vehicles have the disadvantages of poor combustion performance, insufficient combustion power and high production costs.
