[0089] in, figure 1 , 3 , 5, 7, 9, 11, 13, 15, 17, 19, 21, 23 are the effect diagrams when the composite fuel additive is not added in the embodiment of the present invention.

[0090] figure 2 , 4 , 6, 8, 10, 12, 14, 16, 18, 20, 22, 24 are the effect diagrams after adding the composite fuel additive in the embodiment of the present invention and using it for a period of time.

[0091] specifically, figure 1 , 7 , 13, and 19 are respectively the engine cylinder head photos when disassembling and observing for the first time in Embodiments 1 to 4, figure 2 , 8 , 14, and 20 are respectively the engine cylinder head photos when disassembling and observing for the second time in Embodiments 1 to 4; image 3 , 9 , 15, and 21 are respectively the photos of the top of the engine plug when disassembling and observing for the first time in Embodiments 1 to 4, Figure 4 , 10 , 16, and 22 are respectively the photos of the top of the engine plug when disassembling and obser...

Embodiment 1

[0094] A compound fuel additive, which consists of the following components by mass percentage:

[0095] Physical fuel additive 68%; Polyurethane 7%; Polyisobutylamine 12%; Ferrocene 13%. Before using the composite fuel additive, disassemble the engine cylinder head to observe the deposits in the combustion chamber of the vehicle and take pictures, and add the composite fuel additive at a mass ratio of 1:1000 between the composite fuel additive and fuel oil. After driving for 5000km normally, again Disassemble the engine cylinder head sight glass to observe the deposits in the combustion chamber of the vehicle and take pictures.

[0096] Such as Figure 1-6 As shown, by comparing the photos before and after adding the compound fuel additive, it is found that the color of the intake valve becomes lighter, black before adding the additive, and gray after adding the additive; after adding the additive, the carbon deposit on the intake valve begins to crack and fall off (visible t...

Embodiment 2

[0098] A compound fuel additive, which consists of the following components by mass percentage:

[0099] Physical fuel additive 68%; Polyurethane 11%; Polyisobutylamine 7%; Ferrocene 13%; Polyetheramine 1%. Before using the composite fuel additive, disassemble the engine cylinder head to observe the deposits in the combustion chamber of the vehicle and take pictures, and add the composite fuel additive at a mass ratio of 1:500 between the composite fuel additive and fuel oil. After driving for 5000km normally, again Disassemble the engine cylinder head sight glass to observe the deposits in the combustion chamber of the vehicle and take pictures.

[0100] Such as Figure 7-12 As shown, by comparing the photos before and after adding the compound fuel additive, it is found that the color of the intake valve becomes lighter, black before adding the additive, and gray after adding the additive; after adding the additive, the carbon deposit on the intake valve begins to crack and...

Abstract

The invention discloses a chemical fuel oil additive and a compound fuel oil additive. The chemical fuel oil additive comprises the following components in percentage by mass: 20-34% of polyurethane, 23-40% of polyisobutene amine and 39-53% of ferrocene; and the compound fuel oil additive comprises the following components in percentage by mass: 60-80% of a physical fuel oil additive and 20-40% of the chemical fuel oil additive which comprises polyurethane, polyisobutene amine and ferrocene. According to the chemical fuel oil additive and the compound fuel oil additive disclosed by the invention, the chemical fuel oil additive is added based on the physical fuel oil additive so as to ensure that the formation of nozzle deposits and air inlet valve deposits can be effectively controlled, combustion chamber deposits can also be effectively removed, and the production of new deposits can be inhibited. In addition, the compound fuel oil additive disclosed by the invention is safe and environment-friendly to use, and can also be used for effectively reducing the emissions of three major pollutants namely CO, HC and NOX in vehicle tail gas and reducing the emission of PM.

Description

technical field [0001] The invention relates to the field of fuel cleaning, in particular to a chemical fuel additive and a composite fuel additive. Background technique [0002] Affected by the backward refining process and the poor quality of crude oil, the olefin content in my country's motor gasoline is relatively high (24%), which is much higher than the standards of motor gasoline in developed countries such as Europe, America and Japan. Because olefins are unsaturated hydrocarbons, they are easy to oxidize and deteriorate. Therefore, gasoline with high olefin content is easy to form intake system deposits and combustion chamber deposits during use, resulting in reduced engine performance, increased fuel consumption, and worsened emissions. [0003] Studies at home and abroad have proved that adding gasoline detergent to gasoline can inhibit the formation of nozzle deposits and intake valve deposits to a certain extent, and reduce CO and HC emissions. The vast majorit...
