High-cleanness alcohol hydrogen oil for compression-ignition internal combustion engines and preparation method thereof

Abstract

The invention discloses a high-cleanness alcohol hydrogen oil for compression-ignition internal combustion engines and a preparation method thereof. The high-cleanness alcohol hydrogen oil for compression-ignition internal combustion engines is prepared from the following components in parts by weight: 26.5-55 parts of methanol, 21-36 parts of benzene, 17-32 parts of petroleum ether, 4-9 parts of cyclohexane and 1.5-5.0 parts of assistant. The assistant comprises a modifier, an oxidizer, an activator, an antiknock, a stabilizer, a foam reducing composition, a detergent dispersant, a cosolvent, a catalyst, a high-efficiency combustion improver, a metal corrosion inhibitor and an antiwear additive. By adding various assistants, the method solves the problem that the methanol can not be easily dispersed stably and can be easily accumulated and separated in fuel in the methanol fuel and additives thereof, and also solves the problems of poor stability, lower flash point, lower cetane number, poor ignition characteristic, metal corrosion, hot air resistance, rubber swelling, foaming and the like in the existing alcohol hydrogen oil.

Description

technical field [0001] The invention relates to the field of fuel preparation, in particular to a high-clean hydrogen alcohol oil for compression ignition internal combustion engines and a preparation method thereof. Background technique [0002] Methanol fuel is a new type of fuel, which shows greater advantages in terms of performance and practical application. Its boiling point is lower than that of diesel fuel, and the mixture gas is formed faster and more uniformly. Wide, so its combustion speed is fast, which is conducive to complete combustion and reduces smoke exhaust. Studies have shown that the concentration of carbon particles in the combustion of alcohol hydrogen oil is very low, and it is basically smokeless; and methanol has a large latent heat of vaporization. When the mixture is used, the intake air temperature will be reduced, thereby increasing the air charge coefficient, which can improve the combustion of the engine to a certain extent, increase the t...
