Problems solved by technology

[0002] The exhaust of most automobiles is directly discharged into the air without any treatment. Because the exhaust of automobiles contains a large number of harmful substances, the components of automobile exhaust contain CO2, CO, NOx, oil gas, ashes and other substances. These substances have a direct impact on the environment. Emissions can cause serious pollution to the environment
[0003] The research on exhaust gas cleaners or additives for diesel vehicles is relatively common, but the application effect is not ideal, and there are still the following problems: poor miscibility, unstable when the engine is running at high speed, and easy to produce by-products; the formula is not energy-saving and environmentally friendly, It is highly corrosive, and the combustion rate of diesel is not significantly improved; after adding methanol, it is easy to have alcohol-oil stratification and poor start-up in cold weather

Abstract

The invention provides a diesel energy-saving and cleaning synergist. The diesel energy-saving and cleaning synergist is composed of methanol, n-butanol, n-octanol, hexamethyl butyl ether, butanone oxime, nonylphenol polyoxyethylene ether, polyoxyethylene Ether amine, polyisobutylene succinimide, polymethoxy dimethyl ether, tert-butyl octyl ferrocene. The mixed fuel obtained by mixing the diesel energy-saving cleaning synergist of the present invention with diesel oil is clear and transparent at normal temperature, has good stability, can effectively reduce the amount of carbon deposition and coking and the fuel consumption of diesel oil, and reduce the emission of CO and HC compounds. Increase the cetane number of fuel.

Description

technical field [0001] The invention relates to the field of petrochemical technology, in particular to a diesel energy-saving cleaning synergist and a preparation method thereof. Background technique [0002] The exhaust of most automobiles is directly discharged into the air without any treatment. Because the exhaust of automobiles contains a large number of harmful substances, the components of automobile exhaust contain CO2, CO, NOx, oil gas, ashes and other substances. These substances have a direct impact on the environment. Emissions can cause serious pollution to the environment [0003] The research on exhaust gas cleaners or additives for diesel vehicles is relatively common, but the application effect is not ideal, and there are still the following problems: poor miscibility, unstable when the engine is running at high speed, and easy to produce by-products; the formula is not energy-saving and environmentally friendly, It is highly corrosive, and the combustion ...
