Abstract

The invention discloses an ashless diesel oil cleaning synergist and a preparation method thereof. The ashless diesel oil cleaning synergist is prepared from methanol, fatty acid, isobutanol, naphthenic acid, solvent oil, dimethyl tert-butyl ether, bis(butanediphthalimide) and organic peroxide. By adjusting the raw material composition, the prepared diesel oil cleaning synergist is clear and transparent liquid. The synergist can be mutually dissolved with diesel oil when being added into diesel oil, and the phenomena of emulsification and separation can not occur in the use process. The synergist disclosed by the invention can effectively remove sediments, avoid blockage of an oil nozzle and improve the quality of diesel oil, so that the energy consumption of a diesel engine is reduced, and the effects of energy conservation and emission reduction are truly realized. After the diesel oil cleaning synergist is added into diesel oil, the diesel oil is strong in power, and exhausted tailgas is more environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of diesel oil detergent synergists, in particular to an ashless diesel oil detergent synergist and a preparation method thereof. Background technique [0002] When the diesel engine is overloaded for a long time, the combustion quality of diesel is poor, and the combustion is incomplete, etc., deposits will be generated in the engine oil supply system, which will partially or completely block the fuel injector, resulting in increased engine workload, Serious problems such as incomplete combustion, increased pollutant emissions and increased fuel consumption. [0003] The addition of diesel detergent can effectively remove deposits, reduce exhaust emissions, and reduce fuel consumption. Diesel detergent, also known as detergent and dispersant, is generally a high-efficiency surface active substance of a certain structure, which plays a role in cleaning and dispersing diesel engines through neutralization, wa...
