Natural nano silicon dioxide powder modified methanol gasoline

Abstract

The invention discloses a natural nano silicon dioxide powder modified methanol gasoline and relates to fuels, in particular to a methanol gasoline which contains 85 percent of methanol, 11 percent of gasoline 90 and 4 percent of methanol modifier combining natural nano silicon dioxide powder in 5,000-6,000 meshes with a chemical raw material. Under the condition that the content of the methanol is not smaller than 85 percent in the gasoline, after the methanol modifier combining natural nano silicon dioxide powder (SiO2) in 5,000-6,000 meshes with the chemical raw material is added, the gasoline can be directly used for mutual dissolution instead of any national standard gasoline; and an engine can be normally started for working at the temperature of 35-30 DEG C. Compared with a gasoline automobile using conventional gasoline, the gasoline automobile using the product of the invention reduces the discharge of carbon dioxide (CO2) and nitric oxide (NOx) in tail gas by more than 85 percent and has no gas blockage phenomenon on an automobile oil path and no corrosion on automobile parts without changing an engine.

Description

technology field; [0001] The invention belongs to the technical field of fuels and comprises modified synthetic gasoline with methanol as the main raw material. Especially relate to a kind of methanol modifying agent natural nano silicon dioxide 5000-6000 mesh powder (SiO 2 ) Methanol modifier combined with chemical raw materials. Background technique: [0002] The continuous rise of international oil prices has brought economic development problems and energy shortage problems to our country. For this reason, the country attaches great importance to the research and development of new energy sources of petroleum substitutes. Methanol has been recognized as a promising and clean alternative energy source for internal combustion engines at home and abroad. The "Methanol for Vehicle Fuel" standard promulgated by the National Standards Committee is the legal basis for the transformation of methanol from chemical products to fuels. The "Methanol Gasoline for Vehicles (M85)" ...

AI Technical Summary

Problems solved by technology

[0003] At present, there are more than 80 open invention patents for methanol gasoline in the existing technology in our country, but the common disadvantage is to modify the automobile engine. In addition, for the internal and external characteristics of the gasoline engine, because the heat value of methanol is half of that of gasoline, and the air mixed gas The calorific value of methanol gasoline is close to that of gasoline mixture, so methanol gasoline has the following problems: For the pipeline of the oil delivery system, the corrosion of the seal, the swelling of the material, the thermal vapor resistance, the difficulty of cold start, and the separation of the water phase are difficult to solve.

According to domestic methanol gasoline, it is only suitable for gasoline vehicles with high compression ratio, but cannot be used for gasoline vehicles with low compression ratio.
