Problems solved by technology

This method has low material cost, fast cleaning speed and good effect, but it requires high professional technical requirements and high service cost. In addition, this method cannot be used for cleaning diesel engine fuel system and exhaust system.
Fuel additive cleaning is to inject a surfactant-type cleaner into the fuel tank to slowly dissolve the scale. This method is simple to use, but the additives are mainly polyetheramine and polyisobutylene amine, which are expensive. At the same time, the scale is added with the required additives. Difficult to control the dosage--a small dosage has no effect, and a large dosage will cause secondary fouling in the combustion chamber, and the cleaning effect is invisible. In addition, this method cannot be effectively used for cleaning the exhaust system

Abstract

The invention discloses a composition, its preparation method and application and an automobile engine fuel tank. The composition comprises the following ingredients (by mass): an organic solvent composed of at least three of the following ingredients: 0% to 30% of aromatic hydrocarbon, 0% to 15% of ester, 0% to 30% of acetone, 20% to 50% of alcohol, 5 % to 30% of ether and 0% to 10% of dichloromethane; a surfactant composed of at least three of the following ingredients: 0-10% of polyether amine; 0-5% of polyisobutylamine, 0-5% of polyisobutene succinimide, 0-10% of monoethanolamine and 0-10%of triethanolamine. The mass percent of the organic solvent is 70-95%, and the mass percent of the surfactant is 5-30%. The composition has clear and transparent appearance. The heat of combustion ofthe composition is less than or equal to the heat of combustion of fuel oil and greater than or equal to 2500 kJ / kg. The composition has the same copper sheet corrosivity with the fuel oil. By the method, the composition can be prepared. The composition can be applied to automotive engine full and exhaust system cleaning. The fuel tank can prompt the cleaning time.

Description

technical field [0001] The invention relates to the technical field of compositions, in particular to a composition, its preparation method, application and automobile engine fuel tank. Background technique [0002] After the car engine has been working for a period of time, it will produce sludge, colloid, and carbon deposits in the fuel system (fuel pump, fuel pipe, fuel injector, intake valve, combustion chamber), and in the exhaust system (exhaust valve, exhaust pipe, Three-way catalytic converters, selective reduction catalytic converters, etc.) produce carbon deposits, sulfur, phosphorus, manganese and other compound deposits, which are the root causes of incomplete combustion of fuel, increased exhaust emissions and decreased engine power, and must be cleaned regularly . [0003] The cleaning of the engine fuel system and exhaust system mainly includes disassembly cleaning, washing machine cleaning, hanging bottle type and self-pressurized non-disassembly cleaning, f...
