Description

Technical Field

[0001] The invention belongs to the technical field related to diesel additives, and specifically relates to a fuel-saving and emission-reducing diesel cleaning synergist and a preparation method thereof. Background Art

[0002] Diesel is a mixture of alkanes, cycloalkanes, aromatic hydrocarbons and a small amount of sulfur, oxygen, and nitrogen hydrocarbons (with carbon atoms of about 10 to 22). It is mainly used as fuel for tractors, large vehicles, internal combustion locomotives, civil engineering, excavators, loaders, fishing boats, diesel generators, and agricultural machinery. Diesel will produce insoluble colloids during storage, transportation, and use, which makes it difficult for diesel to burn completely, and forms deposits such as carbon deposits in filters, nozzles, and combustion chambers, resulting in reduced thermal efficiency and increased fuel consumption, which seriously affects engine power. Therefore, it is necessary to design a fuel-saving and emission-reducing diesel detergent and preparation method. With the continuous improvement of engine power performance requirements and the development and popularization of high-pressure common rail diesel engines, the operating pressure and temperature of fuel injectors have increased, and deposits are more likely to form. Although the existing single-main diesel detergent has a certain cleaning effect, it has almost no combustion-supporting, smoke-eliminating, and power-enhancing effects, and it is difficult to adapt to the progress of engine technology. Diesel detergent enhancer has the effect of improving the quality of diesel. It is multifunctional, saves fuel, reduces emissions, enhances power, facilitates cold car starting, reduces noise, and extends engine life. It is a common need of environmental protection and consumers. Summary of the invention
