Problems solved by technology

The problems of conventional small molecule amine detergents are: poor thermal stability under high temperature conditions and inability to effectively control the formation of carbon deposits and sediments
Polymerized detergents are mainly based on the research of polyisobutenylamine. The method of adding carrier oil, carrier oil, solvent oil, and polymerization inhibitor to the prepared polyisobutenylamine is used to prepare gasoline detergents. Although such gasoline detergents can The purpose of removing carbon deposits is achieved, but there is still the problem that the effect of removing carbon deposits on the intake valves of gasoline engines is not obvious

Abstract

The invention belongs to the technical field of fuel additives, and particularly relates to a fuel deterging and dispersing agent. The fuel deterging and dispersing agent is prepared from alcohols, propiconazole, 2-methylpyridine, hexamethylphosphoramide, N-methylformamide and polyoxyethylene castor oil; the alcohols are one or more of 2-pyridinemethanol, isobutanol, isopropanol, 1-heptanol, 2-octanol and 1-hexanol. By the adoption of the fuel deterging and dispersing agent, carbon deposits in fuel spray nozzles, air inlet valves and combustion chambers of engines are effectively removed, the deterging and dispersing effects are good, the cleanliness of the engines is ensured, the good operation of the engines is guaranteed, and the generation of carbon deposits and sediment in the engines is prevented.

Description

technical field [0001] The invention belongs to the technical field of fuel additives, in particular to a fuel cleansing and dispersing agent. Background technique [0002] With the rapid development of the automobile industry, the number of automobiles in my country is increasing rapidly. While automobiles bring convenience to people's production and life, they also increase the consumption of petroleum resources and the emission of harmful exhaust substances. In addition, when the car is running, the engine cannot completely burn due to insufficient oxygen supply, and after the engine is turned off, the volatile wax and gum in the gasoline will harden when heated, and the quality of the oil will form carbon deposits, which will affect the normal operation of the engine. Very large, such as causing lax valve closure, air leakage from the intake valve or exhaust valve, knocking, etc. At present, an effective measure to solve the problem of carbon deposition is to add deterg...
