Embodiment approach

[0025] According to one embodiment of the present invention, said comprising C 4 h 8 The structural formula of nonylphenol polyetheramine with O structure is:

[0026]

[0027] Wherein, the x is an integer of 7-12.

[0028] According to one embodiment of the present invention, the total weight of the engine intake valve deposit cleaning composition is 100% by weight, the 4 h 8 The content of nonylphenol polyetheramine with O structure is 40-70% by weight, preferably 50-65% by weight.

[0029] According to one embodiment of the present invention, said comprising C 4 h 8 The nonylphenol polyetheramine with O structure can be selected from PEA-B purchased from Hunsman Company (Hunstamn Company).

[0030] In the present invention, the amine group contained in the oleylamine (oleylamine) has polarity and surface activity, which can promote the inclusion of C 4 h 8 Nonylphenol polyetheramine with O structure can more effectively disperse intake valve deposits.

Abstract

The invention provides a composition for cleaning engine intake valve deposits, which comprises: (a) 40-70% by weight of C 4 h 8 O-structure nonylphenol polyetheramine; (b) 10-20% by weight oleylamine; and (c) 20-45% by weight alkyl alcohol. The engine intake valve deposit cleaning composition provided by the invention has good intake valve deposit cleaning ability.

Description

technical field [0001] The invention relates to a composition for cleaning engine intake valve deposits, a method for preparing the composition for cleaning engine intake valve deposits, and a method for cleaning engine intake valve deposits. Background technique [0002] Automobile engines are prone to deposits on intake valve surfaces due to the oxidation and polymerization of hydrocarbon fuels. These deposits, even in relatively small amounts, can significantly increase a car's fuel consumption and production of exhaust pollutants. [0003] There are some cleaners available in the prior art for removing deposits on the intake valves of automobile engines. For example, US5006130 discloses a fuel additive for reducing intake valve deposits in electronic port fuel injected engines comprising (a) a mixture of basic nitrogen of about 2.5% (ppmw) or higher, based on fuel Components in the form of oil-soluble aliphatic alkylene polyamines having a molecular weight of from abou...
