Description
Canadian Patent Application based on Attorney Docket No. 21871-80 Chinese Appin. No. 201910203936.4 A DETERGENT APPLIES TO ALL LIQUID FUEL
Technical Field The present invention relates to the field of fuel detergents, and more particularly to a detergent suitable for liquid fuel and a preparation method thereof background technology China's car ownership has increased dramatically, and environmental pollution caused by fossil fuel combustion and emissions cannot be ignored. During the operation of the automobile, the deposits generated by the engine intake system and the combustion chamber will seriously affect normal injection, atomization, mixing and combustion of the fuel, which results in reduction of performance of the vehicle's engine, the power and fuel efficiency will be reduced, and the emissions will worsen, further damaging the environment. At present, gasoline vehicles used in China, especially small cars, mainly use electronically controlled fuel direct injection technology. The application of this technology places higher demands on the quality of fuel used. Olefin and some heavy aromatics in gasoline are prone to oxidative decomposition at high temperatures, further generating coke and colloid in the engine, which seriously affects the working condition of the engine, resulting in power reduction, increased emissions, and increased fuel consumption. The fuel nozzles, intake valves and combustion chambers of the engine are the most easily generated deposits. How to reduce engine carbon deposits, reduce vehicle exhaust emissions, and improve the economics of oil products is currently a research hotspot.
Therefore, the research, development and application of fuel detergents are in full swing.
At present, the research on detergents can be roughly divided into four generations: the first generation originated in the 60's and 70's of the last century, mainly for carburetor sediments, the components are mainly low molecular amine compounds; the second generation is 80's-90's In the age of the fuel injections Canadian Patent Application based on Attorney Docket No. 21871-80 Chinese Appin. No. 201910203936.4 engines, the main component is polyisobutylene succinic acid compound; the third generation since the 1990's, in addition to clean fuel nozzle deposits, but also for the intake valve gel, carbon deposits; mainly for polyisobutylene amines and Mannich base ash free dispersants; the fourth generation under current research is a detergent made of polyisobutyl amine, it has an excellent cleaning effect on carbon deposition in fuel nozzles and inlet valves, but it is also difficult to decompose, so it is easy to enhance carbon generation of the combustion chamber. Using polyisobutylene amine as a detergent, has excellent cleaning effect on fuel nozzle and intake valve carbon deposit, but it is easy to increase the carbon deposition in the combustion chamber because of its difficulties to decompose; polyether amine detergent has a outstanding effect to inhibit carbon deposition within the combustion chamber, but the cleaning effect on high temperature parts is not as good as the third generation detergent.
Therefore, there is a demand for a detergent which not only has excellent cleaning ability for coke within the general combustion area, but also has an excellent cleaning effect on high-temperature components, without increasing the buildup of harmful carbon deposits inside the combustion chamber.
Contents of the invention In order to solve the above technical problems, the first aspect of the present invention provides a detergent suitable for a liquid fuel, the raw material comprising at least but not limited to, a vegetable oil, a fatty acid alkyl alcohol ester and an amino acid ester.
The total number of carbon atoms in the fatty acid alkyl alcohol ester does not exceed 44.
As a preferred technical solution, the total number of carbon atoms in the fatty acid alkyl alcohol ester is 15-40.
As a preferred technical solution, the raw material further includes a cyclodextrin.
