Problems solved by technology

For this reason, many domestic enterprises and individuals began to study methanol diesel, but encountered many problems in the process of experimental use: the miscibility and stratification of methanol after adding diesel, the power drop and speed impact of methanol diesel, the use of methanol diesel The problem of corrosion of oil circuit and cylinder, corrosion and swelling of rubber and plastic parts, low flash point and cetane number, etc., the key is that the methanol diesel additive technology has not been solved well, resulting in the failure of the existing methanol diesel oil. Solve problems such as miscibility, power, emulsification, corrosion, flash point and cetane number effectively

Abstract

The invention discloses methanol-diesel for vehicle. According to volume portion, the composition formulation comprises 20 to 65 portions of diesel oil, 30 to 70 portions of methanol, 0.5 to 1.5 portions of oleic acid, 0.5 to 2.0 portions of ethyl acetate, 0.5 to 1.0 portions of diphenyl carbonate, 0.5 to 1.5 portions of petroleum ether, 0.3 to 0.7 portions of cyclopentyl ferrocen, 0.2 to 0.8 portions of nitric acid iso-octyl, 0.5 to 2.0 portions of normal butyl alcohol and 0.5 to 1.5 isobutyl alcohol. The formulation is suitable for the normal diesel oil of any label, the technical problems that the methanol-diesel is easy to be delaminated and the low temperature cool start is imperfect are solved, and the source of the required raw materials and auxiliary materials is wide and the price is low; the cetane value of the formulated methanol-diesel for vehicle can reach 57, the flash point can reach 88 DEG C, and the exhaust emission is accorded with the requirements of the 3# European standard; the using of the methanol-diesel for vehicle has important social significance and economic value for energy conservation and environmental protection.

Description

technical field [0001] The invention relates to a methanol diesel for vehicles, which belongs to the technical field of clean fuels. Background technique [0002] In the late 20th century, affected by the rise in international oil prices and the shortage of oil resource supply, there was a serious shortage of diesel oil at home and abroad, which brought great inconvenience to economic development and people's lives. In order to solve the shortage of diesel oil In order to solve the problem, the state has issued many relevant policies to encourage the development of diesel alternative energy. Since methanol has an oxygen content of 50%, it has good combustion performance and low emission pollution. Therefore, it has been recognized as a promising and clean alternative fuel for internal combustion engines. For this reason, many domestic enterprises and individuals began to study methanol diesel, but encountered many problems in the process of experimental use: the miscibilit...
