Problems solved by technology

US5139534 discloses a kind of cleaning agent that reduces diesel engine nozzle pollution, and its composition is fatty amine and fatty amide, because said fatty amine and fatty amide are straight-chain hydrocarbon groups, oil solubility is relatively poor, can affect its stability in diesel oil and oxidation stability
CN1031889C discloses a manufacturing and application method of a diesel additive, which is mainly prepared by dissolving alkenyl succinimide, alkylphenol and benzotriazole derivatives in diesel, but the additive is mainly used to improve the Storage stability, no improvement in performance
The agent is effective for cleaning the oil circuit, but it cannot solve the lubricity problem of low-sulfur diesel oil, and its ability to emit and suppress particulate matter is insufficient

Embodiment 1

[0019] The distribution ratio of each component of embodiment 1 diesel oil detergent is as follows:

[0020] 1) 20 parts (weight, the same below) polyisobutylene succinimide (polyisobutylene number average molecular weight 1000, Suzhou Special Oil Factory product);

[0021] 2) 5 parts of isobutylene trimerized C12 primary amine;

[0022] 3) 5 parts of 2-methylimidazole;

[0023] 4) 5 parts of glyceryl oleate;

[0024] 5) 65 parts of high flash point aviation kerosene.

Embodiment 2

[0038] 1) 15 parts of polyisobutylene succinimide (polyisobutylene number average molecular weight 1300, product of Suzhou Special Oil Factory);

[0039] 2) 5 parts of isobutylene trimerized C12 primary amine;

[0040] 3) 5 parts of 2-phenylimidazole;

[0041] 4) 5 parts of glyceryl oleate;

[0042] 5) 70 parts of heavy aromatic solvent (flow process 170-210°C).

Embodiment 3

[0044] 1) 25 parts of polyisobutylene succinimide (polyisobutylene number average molecular weight 1300, product of Suzhou Special Oil Factory);

[0045] 2) 20 parts of propylene tetrapolymer C12 primary amine;

[0046] 3) 10 parts of 2-methylimidazole;

[0047] 4) 15 parts of glyceryl oleate;

[0048] 5) 30 parts of heavy aromatic hydrocarbon solvent (flow process 170-210°C).

[0049] In order to illustrate the cleaning action of the diesel oil detergent provided by the present invention, the special diesel oil detergent prepared in Example 1 is added in No. 0 commercially available diesel oil, and it is loaded into 4 diesel vehicles and carried out the driving test of 3 weeks. The diesel vehicles without additives were tested (1, 2, 3 are large trucks; 4, 5 are large passenger cars). Measure the smoke of the vehicle before and after the test according to the GB / T3846 method, measure the nozzle air flow according to the ISO4010 method, and observe the fuel consumption. The...

Abstract

The invention discloses a diesel detergent additive, which comprises the following components by weight percent: 15-60% of polyisobutylene succinimide, 5-20% of polyolefin amine, 5-20% of alkyl imidazole, 5-15% of glyceryl monooleate and 20-70% of organic solvent. The diesel detergent additive of the invention has good effects on cleaning oil ways of a diesel vehicle and eliminating carbon deposition of an oil nozzle, simultaneously can improve lubricating property of the diesel, improve exhaust emission and save the diesel.

Description

technical field [0001] The invention relates to a diesel detergent, more precisely, it is a diesel additive for cleaning the oil circuit system of diesel vehicles and reducing tail gas emissions. Background technique [0002] With the development of refinement of diesel engines and the needs of the environment, the requirements for the cleanliness of diesel are increasing. World fuel standards, EU fuel standards, American fuel standards and many other countries' fuel standards and the Automobile Manufacturers Association have stipulated that detergents must be added to vehicle diesel, and specified specific limit data. my country has also issued gasoline detergents. National standard, and diesel standards in line with international standards will be introduced one after another. It can be seen that the use and development of diesel detergents is inevitable in my country, and is the common needs of consumers and environmental protection. [0003] US4484357 once disclosed a c...
