Technical Field

The invention relates to an energy-saving emission-reducing gasoline additive and a preparation method thereof, belonging to the field of petrochemical industry.

Background

Gasoline is the main fuel of traffic vehicles, and because colloidal substances and olefin contained in the gasoline can cause the generation of oil dirt and carbon deposit on an engine, the blockage of an oil way of a valve and the like is caused, the incomplete combustion is caused, the power performance is reduced, the oil consumption is increased, the emission of harmful substances is increased, and the environmental pollution is aggravated.

Chinese gasoline is mainly composed of catalytic cracking components, and has high olefin content, and the olefin is easy to oxidize and condense at high temperature to form precipitate.

At present, the domestic gasoline additive is mainly a detergent product, and has a certain cleaning effect on carbon deposit and oil dirt of an engine cylinder and an oil way. Although the cylinder and the oil way can be unblocked through cleaning, thereby improving the utilization rate of fuel oil and protecting the engine, the engine does not fundamentally promote the combustion of the fuel oil, does not solve the problem of the full utilization of the fuel oil by the engine, and can not thoroughly prevent the formation of oil dirt and carbon deposit.

In addition, most of the existing gasoline additives are high in cost and cannot be added into gasoline in a large proportion, the gasoline is non-renewable resources in the week, and the additives can be obtained by adding the additives into the gasoline in a large proportion.
