Abstract

The multifunctional diesel oil detergent includes the following components: polyisobutenyl succimide 5-40 %, bononized ash-free dispersant 5-30 %, polyetheramine 5-30 %, alkyl RE 1-5 %, alkyl nitrate 5-15 %, organic acid ester 3-10 % and organic solvent 10-70 %. The present invention is used for cleaning oil path, especially nozzle, in diesel engine, and can eliminate carbon deposit, reduce black smoke, improve lubricating performance, resist emulsification, resist corrosion, save oil and reduce exhaust.

Description

technical field [0001] The invention relates to a composite agent of a diesel detergent composition, in particular to a multifunctional diesel detergent, which belongs to the technical field of fuel oil additives. Background technique [0002] As we all know, the development of diesel vehicles in the world is very rapid, and the manufacture of diesel engines is becoming more and more refined. Therefore, the requirements for the cleanliness of diesel are also getting higher and higher. Adding diesel detergent is one of the methods commonly used in foreign developed countries. The proportion of diesel vehicles in my country is also increasing year by year, and the quality of diesel in my country is still far behind the international level. Due to the large amount of catalytic cracking components in diesel, the high content of unsaturated hydrocarbons and impurities is more likely to form in engine nozzles and other parts Carbon deposits and deposits affect the normal operation...
