Abstract

The invention relates to an automobile gasoline composite modifying agent. The raw material of the modifying agent is prepared from the following components in percentage by weight: 25-50% of an octane value promoter, 30-50% of a combustion improver and 20-25% of a latent solvent, wherein the octane value promoter comprises the following components in percentage by weight: 20-45% of sec-butyl acetate, 30-40% of diisopropyl ether, 5-10% of absolute ethyl alcohol and 20-30% of methyl tert-butyl ether; the combustion improver comprises the following components in percentage by weight: 10-20% of cyclopentane, 47-50% of mixed light arene, 30-40% of alkylate and 3-6% of 1# jet fuel; and the latent solvent comprises the following components in percentage by weight: 10-30% of acetone, 25-30% of dimethoxy ethane, 20-25% of industrial isobutyl alcohol, 22.5-28% of industrial isopropyl alcohol, 1-4% of trinitromethane, 1-2% of glycol ethylene ether, 0.1-0.2% of a clearing agent polyisobutene succinimide, 0.2-0.4% of a metal deactivator T1201 and 0.2-0.4% of an antioxidant. By adopting the automobile gasoline composite modifying agent, a three-way catalyst of an organic ashless exhaust system cannot be poisoned, a fuel spray nozzle and a cylinder exhaust valve cannot be abraded, and carbon deposition and abrasive particles cannot be generated in a machine body.

Description

Technical field [0001] The invention belongs to the field of petrochemical industry, and relates to a composite gasoline regulator for vehicles, belonging to an organic ashless class. The compound regulator is suitable for unleaded gasoline, ethanol gasoline, and fuel oil based on gasoline component mixture. Background technique [0002] At present, the tight supply and demand of petroleum resources directly endangers our national security. Faced with the increasingly prominent problems of domestic petrochemical energy supply contradictions, if we can ensure environmental requirements and meet automobile exhaust pollutant emission standards, we will consider the following four aspects and adopt technical methods and measures to develop existing refined gasoline products. The quality and upgrading of order has practical guiding significance and long-term development strategic significance for my country's energy-leading policy for sustainable development. In the 1920s, the United...
