Coal-based gasoline auxiliary agent

Abstract

The invention provides a coal-based gasoline auxiliary agent which is composed of the following in percentage by weight: 3-35% of nitromethane or nitroethane, 20-65% of methyl-carbonate, 5-35% of methyl acetate, 10-45% of vinyl acetate, and 4-30% of ethyl nitrate. The test results show that a coal-based gasoline fuel obtained by mixing the gasoline auxiliary agent provided in invention and No.93 gasoline at a volume ratio of 1:2 has a high octane number and is low in cost; the power performance, fuel economy, cleanness, wear, emission and other indices of the coal-based gasoline fuel all meet the national standards; after the engine runs for 100 hours, as compared to gasoline, the torque is reduced only by 1.5%, the power is reduced by 0.8%, and the fuel consumption rate is reduced by 0.44%; the cleanness is better than that of gasoline and the wear loss of major moving parts is equivalent; CO, CO2, NOx, PM and other emissions in the combustion exhaust gas can be greatly reduced as compared with commercially-available gasoline products, in which the NOx emission is reduced by 52.7% as compared with gasoline.

Description

technical field [0001] The invention belongs to the technical field of new energy, and in particular relates to a low-energy and high-efficiency gasoline additive. Background technique [0002] In recent years, the use of internal combustion engines in my country's automobile and transportation industries, including marine transportation, has increased the demand for petroleum resources. The remaining recoverable oil quantity in my country is only about 2.2 billion tons, and the reserve resources are seriously insufficient. According to the current output, oil will be exhausted in 12 years. However, oil imports have been heavily interfered by international hegemonic countries, leading to soaring prices, seriously affecting and restricting the development of my country's national economy and the security of the people's livelihood. Therefore, striving to achieve energy self-sufficiency is a crucial issue to ensure the sustainable development of our country. [0003] The exp...
