Problems solved by technology

[0003] Commercially available detergent main agents include polyisobutylene amine, Mannich base, and polyetheramine. Commercially available polyetheramine cannot be used alone because of its low decomposition temperature and poor detergency on intake valves and fuel injectors. It is generally used in combination with polyisobutenylamine or Mannich base detergents. Although polyisobutenylamine and Mannich base detergents are good for cleaning intake valves and fuel injectors, due to their high decomposition temperature , will inevitably lead to a significant increase in the deposits in the combustion chamber, and the detergency effect of the combustion chamber cannot be well exerted; at the same time, Mannich base, polyisobutylene amine, and commercially available polyetheramine detergents are efficient surface active substances, and the interfacial tension Larger, it is easy to cause the emulsification of the added oil, affecting the sales and use of the oil

Abstract

The invention belongs to the field of petrochemical engineering, and particularly relates to a polyether amine type detergent. The detergent comprises, by mass, 15-37% of polyol polyether amine, 0.5-5% of an octane number improver, 2-7% of an antioxidant, 10-15% of a combustion improver and 0.3-1% of a corrosion inhibitor, with the balance being a solvent A. According to the polyether amine type detergent, the polyol polyether amine is used as a detergent; Mannich base and polyisobutene amine detergents do not need to be added any more, and the polyether amine type detergent is excellent in detergency, can clean sediments formed by an engine, can prevent production of sediments, cannot emulsify agent-added oil products, can obviously reduce oil consumption, reduces tail gas emission and cannot cause secondary pollution to an engine combustion chamber.

Description

technical field [0001] The invention belongs to the field of petrochemical industry, and in particular relates to a polyetheramine type detergent. Background technique [0002] At present, small car engines are gradually changing to electronically controlled fuel direct injection technology, and the application of this technology puts forward higher requirements for the quality of the fuel used. This is because olefins and some heavy aromatics in gasoline are prone to oxidative decomposition at high temperature, further forming carbon deposits and colloids in the engine, which seriously affects the working conditions of the engine, resulting in decreased power, increased emissions, and increased fuel consumption. The fuel nozzle, intake valve and combustion chamber of the engine are the places where deposits are most likely to form. In order to solve the problem of engine deposits caused by the high content of olefins and aromatics in gasoline, adding gasoline detergent to g...
