Abstract

The invention relates to the field of oil product additives, in particular to a composite high-cleanness fuel oil additive and aims at providing a composite high-cleanness fuel oil additive for improving the dynamic properties, cleanness and corrosion and abrasion resistance of fuel oil and a preparation method thereof. The composite high-cleanness fuel oil additive is prepared from, by mass, a detergent main agent 10-60%, an anti-abrasion agent 0-10%, a corrosion inhibitor 0-10%, an antioxidant 0-5%, carrier oil 15-40% and the balance a thinner, wherein the detergent main agent is one or more of polyisobutylene phenol mannich base, PEA polyether amine and polyisobutylene amide. The fuel oil adopting the composite additive has good cleanness, the colloid, carbon deposition and coking at automobile jet nozzles, throttle valves, combustion chambers and other parts can be obviously reduced, the abrasion of components of a fuel system can be reduced, the oxidative deterioration of the fuel oil and the additive can be inhibited, and the harmful substances in engine tail gas emissions can be reduced.

Description

technical field [0001] The invention relates to the field of oil additives, in particular to a high-clean gasoline and diesel composite additive. Background technique [0002] Carbon deposition is an unavoidable phenomenon during engine operation. Due to the existence of unsaturated hydrocarbons in vehicle fuel, in addition to directly affecting exhaust emissions, it is more likely to cause deposits in engine injectors, throttle valves, combustion chambers, etc. , especially for advanced direct injection engines and supercharged engines, the structure of the direct fuel injection system will aggravate the generation of carbon deposits, and the carbon deposits on the back of the intake valves are more difficult to remove, resulting in reduced engine power and increased fuel consumption. Advanced fuel compound additives are essential to prolong engine life and reduce fuel consumption. [0003] Gasoline and diesel detergents currently on the market generally use solvent oil as...
