Problems solved by technology
Although the high proportion of methanol gasoline has greatly improved the energy substitution rate, it needs to change the electronic control system of the engine when using it, and it is difficult to cold start at low temperature, so the high proportion of methanol gasoline cannot be well promoted and used.

Abstract
The invention belongs to the field of fuels and relates to a vehicle high-proportion methanolgasoline and a preparation method thereof. The vehicle high-proportion methanolgasoline comprises the following components in percentage by weight: 85 to 90 percent of methanol, 3 to 4 percent of solvent oil, 5 to 10 percent of No. 90 national standardgasoline and 1 to 2 percent of additive, wherein the additive is prepared by blending sodiumhexadecyl sulfonate, calciumhexadecyl sulfonate, liquid naphthenic acid, methylal, nitromethane and C3-C8 monohydric alcohol. The high-proportion methanol gasoline of the invention overcomes the disadvantages of the traditional high-proportion methanol gasoline under the condition of no change of the vehicles; each index completely meets the standard of vehicle methanol gasoline M85 of 'GB / T23799-2009'; and the vehicle high-proportion methanol gasoline can be well applied to vehicles.
Description
technical field [0001] The invention belongs to the field of fuel, and in particular relates to a high-proportion methanol gasoline for vehicles, and also relates to a preparation method thereof. Background technique [0002] Energy crisis and environmental pollution are two major problems facing the world today. Therefore, actively seeking and developing clean energy and alternative energy has become a top priority for all countries in the world. Methanol has the characteristics of high oxygen content, high octane number, low environmental pollution, etc., and has a wide range of sources, so it is an ideal alternative fuel for vehicles. The currently used methanol gasoline is mainly low-ratio methanol gasoline with a methanol content below 30% and high-ratio methanol gasoline with a methanol content above 85%. The low proportion of methanol gasoline not only has a low energy substitution rate, but also has high-temperature air resistance and low-temperature stratification ...
