Abstract

The invention belongs to the technical field of gasoline additives, and particularly relates to a gasoline octane number promoter. The gasoline octane number accelerator comprises at least one alcohol-derived compound, a phenol and an additive. At least one alcohol-derived compound does not comprise an ethanol-derived compound, the dry point of the at least one alcohol-derived compound is greaterthan or equal to 100 DEG C, and the viscosity at 20 DEG C is less than or equal to 5.0 * 10 <-3 > Pa.s. The accelerator has the advantages of small addition amount in gasoline, no reduction of the combustion speed of the gasoline, easily available raw materials, very low cost, high efficiency, energy saving, environmental protection, no adverse effect on the gasoline, and substantial improvement of the quality of the gasoline so that the accelerator can be widely used in the gasoline to improve the fuel economy of vehicles combusting the gasoline.

Description

technical field [0001] The invention belongs to the technical field of gasoline additives, more specifically, the invention relates to a gasoline octane booster. Background technique [0002] The normal combustion of an automobile engine starts from the spark plug to form a flame center, and the flame advances to all parts of the combustion chamber at a speed of 20-50m / s, so that the temperature rises evenly. Abnormal combustion is that a part of combustible gas is compressed and thermally radiated. Under the condition of a sharp increase in temperature and pressure, many unstable peroxides are generated. Before the normal flame is transmitted, decomposition and spontaneous combustion occur, resulting in deflagration. That is, detonation. [0003] Octane number is an important index used to measure the antiknock performance of gasoline. Generally speaking, the higher the octane number of gasoline, the better its antiknock performance. For gasoline whose octane number does ...
