Problems solved by technology

It will directly affect the cold start of the car and the charging efficiency of the combustible mixture entering the combustion chamber. In severe cases, it will cause the valve to move slowly and not close tightly
Therefore, methanol gasoline must use a detergent dispersant compared with unleaded gasoline, and the dispersant described in CN101705122A is calcium petroleum sulfonate and magnesium stearate, magnesium isostearate with metal ions; in CN102604692A, Be to use environmental pollution benzene, xylene as the effect of clean and dispersed; In CN1840620B, a large amount of metal salts have been used: polyisobutylene phosphobarium, zinc dialkyldithiophosphate, in CN101285010A, the clean and dispersed components are Propanol, dipentene; in CN102161919A, the cleaning and dispersing components are n-isopropanol, limonene, and cyclohexane, and these components all have certain cleaning and dispersing effects, but the effects are not ideal

Abstract

The invention discloses a cleaning and dispersing agent for bio-based methanol gasoline and a preparation method of the cleaning and dispersing agent. The cleaning and dispersing agent consists of 30-40% of surfactant ingredient, 32-35% of dispersing peat ingredient and 30-35% of cleaning and washing ingredient; and the cleaning and dispersing agent product is prepared through uniformly mixing the three functional ingredients at normal temperature. According to the cleaning and dispersing agent and the preparation method of the cleaning and dispersing agent, cleanable, environmental-friendly, reproducible and degradable petroleum yeast fatty acid is selected as a cheap additive, so that the energy is saved and the emission is reduced; and compared with the prior art, the cleaning and dispersing agent is low in cost, non-toxic, free of pollution, low in dosage and remarkable in cleaning and dispersing effect and cannot cause secondary pollution to the environment. According to the cleaning and dispersing agent and the preparation method of the cleaning and dispersing agent, organic modification is carried out by using substances such as the yeast fatty acid, morpholine and fatty-amine calcium salts, so that the special cleaning and dispersing agent for the methanol gasoline is synthesized; and the cleaning and dispersing agent disclosed by the invention has the advantages that the formation of carbon deposit can be prevented effectively, formed carbon deposit is removed, a fuel injection nozzle, an air inlet valve and a combustion chamber of a gasoline engine are effectively prevented from emergence and production of carbon deposit, and the removal ratio is up to 32.12-64.14%.

Description

technical field [0001] The invention relates to the field of alternative fuels for alcohols, in particular to a bio-based methanol gasoline detergent and dispersant which mainly uses biomass energy and can be blended with bio-alcohols in a high proportion and a preparation method thereof. It can effectively prevent and reduce the carbon deposits in engine fuel injectors, intake valves and combustion chambers. Background technique [0002] For a long time, gasoline and diesel have been the main fuels for various types of motor vehicles. This usage pattern is increasingly restricted by serious environmental pollution and increasingly scarce resources. In order to improve this dilemma, a variety of energy alternatives have been adopted at home and abroad. However, if these alternatives are to be popularized on a large scale, there are serious defects. In recent years, as the international oil price continues to hover at a high level, the promotion, application and research pro...
