Description

Technical Field

[0001] The invention belongs to the technical field of fuel additives, and in particular relates to a fuel power enhancer capable of effectively removing carbon deposits and a preparation method thereof. Background Art

[0002] Due to the continuous reduction of fossil crude oil sources and the increasing awareness of environmental protection in my country, the restrictions on automobile exhaust emissions are becoming increasingly stringent. In order to meet the requirements of emission regulations, in addition to optimizing the engine structure, improving fuel quality is also an important way to achieve engine energy conservation and emission reduction. The use of additives is an effective means to improve gasoline performance. Fuel power enhancer is a fuel additive that can improve engine power performance. It improves fuel power performance by increasing the octane number of the fuel. However, the existing types of fuel power enhancers are relatively single. Polyetheramine-type fuel power enhancers have a high degree of cleaning of carbon deposits inside the engine, but the production cost is high and the thermal stability is poor. The production cost of polyisobutylene amine-type fuel power enhancers is low, but the cleaning effect of carbon deposits inside the engine is not as good as that of polyetheramine, and it may increase carbon deposits in the combustion chamber and affect engine performance.

[0067] Preparation of test gasoline: The fuel power enhancer prepared in each embodiment and comparative example was added into pure No. 92 gasoline at a volume ratio of 1:100.

[0068] Experimental Example 1: During the test gasoline preparation process, the mixing conditions of the fuel power enhancers prepared in each embodiment and comparative example and gasoline were observed. The results are shown in Table 1 below:

[0069] Table 1

[0070] Serial number Mixed situation Example 1 Mix well immediately after adding Example 2 Mix well immediately after adding Example 3 Mix well immediately after adding Example 4 Mix well immediately after adding Example 5 Mix well immediately after adding Example 6 Mix well immediately after adding Example 7 Mix well immediately after adding Comparative Example 1 After adding, let stand for 5 minutes to mix evenly Comparative Example 2 Mix well immediately after adding Comparative Example 3 After adding, let stand for 10 minutes to mix evenly

In Example 2, no metal antiknock agent is added, which has no obvious effect on the compatibility of the fuel power enhancer with gasoline.

[0072] Experimental Example 2: According to GB19592-2019 "Automotive Gasoline Detergents", the fuel power enhancers prepared in each embodiment and comparative example were subjected to various performance tests, including appearance, sulfur content, chlorine content, corrosion resistance, demulsification, and simulated intake valve deposit quality. The test results of various performances are shown in Table 2 below:

[0073] Table 2

[0074]

[0075] It can be seen from the data in Table 2 that the fuel system power enhancer prepared in each embodiment is transparent in appearance, free of suspended matter and precipitated impurities, has a sulfur content less than the prescribed standard of 50 mg / kg, a chlorine content less than the prescribed standard of 10 mg / kg, is free of rust and the demulsification property meets the standard requirements, and the mass of simulated intake valve deposits is between 0.3 and 0.6 mg, which further illustrates that the fuel power enhancer prepared in the present invention meets the standard requirements and has excellent carbon deposit removal performance.

[0076] Experimental Example 3, Wuling Hongguang 1.5LS basic model was used as the test vehicle, and the gasoline prepared in each embodiment and comparative example was used on the vehicle to travel 100 kilometers. At the same time, pure 92 gasoline was used as the control group, and the data of power, octane number, and fuel consumption reduction rate of each group were recorded, wherein the fuel consumption reduction rate is the reduction of the fuel consumption of each test gasoline on the basis of the fuel consumption of pure 92 gasoline after the vehicle traveled 100 kilometers. The results are shown in Table 2:

[0077] Table 3

[0078] Serial number power / % Octane Fuel consumption reduction rate / % Example 1 109 103 5.5 Example 2 110 105 5.7 Example 3 108 102 5.2 Example 4 110 101 5.5 Example 5 109 105 5.6 Example 6 110 103 5.1 Example 7 108 100 5.3 Comparative Example 1 103 95 3.4 Comparative Example 2 102 96 2.5 Comparative Example 3 104 98 2.2 Pure 92 gasoline 100 92 100
