Problems solved by technology

However, we found that in market applications, even if the saturated vapor pressure of methanol gasoline is well suppressed, in the high temperature weather in South China, air lock is still prone to occur when the car travels at a high speed of 2-3 hundred kilometers. Obviously, a single method, Can not completely prevent the occurrence of air lock

Abstract

The invention relates to a methanol gasoline capable of remarkably reducing air resistance. The methanol gasoline comprises the followings components of: 30-50 percent of denatured methyl alcohol and 50-70 percent of modified gasoline, wherein the denatured methyl alcohol consists of methyl alcohol, normal or isometric fatty alcohol, normal or isomeric fatty ether, normal or isometric fatty ketone, an oxidant, a corrosion inhibitor and a soluble involatile compound; and the modified gasoline consists of gasoline, aromatic hydrocarbon, naphtha, a defoaming agent and an activating agent. The methanol gasoline capable of remarkably reducing the air resistance, disclosed by the invention, solves the problem that air resistance is easy to happen in the using process of the methanol gasoline by adopting multiple measures aiming at various formation causes of the air pressure of the methanol gasoline and has the advantages and effects of wide adaptability, suitability of use in extreme weather, simple and easy production, low cost, good using effect and greatly-increased using safety of the methanol gasoline.

Description

technical field [0001] The invention relates to methanol gasoline capable of significantly reducing air resistance, belonging to the field of automobile alcohol ether substitute fuels. Background technique [0002] Methanol gasoline has good economy, environmental protection and safety. As an alternative energy source for vehicles, it will be an effective way to solve the tension between supply and demand. However, when methanol gasoline is used in the hot summer, the gas lock phenomenon will appear in Louis Vuitton. Vapor resistance is the gas state produced by the evaporation of part of the fuel oil in the oil supply system of the internal combustion engine when the ambient temperature is above 31°C. It exists in the oil pipe and gasoline pump, which not only increases the flow resistance of gasoline, but also due to the compressibility of the gas, In this way, the oil vapor in the oil pipe and oil pump is continuously compressed and expanded with the pulsating pressure o...
