Above-mentioned five kinds of additive formulations have been carried out the detergency simulation test respectively.The detergency simulation test comprises fuel oil oxidation test and intake valve carbon deposit simulation test.Fuel oil oxidation test employing 440C stainless steel is dipped in the gasoline and reacts 48h with the 2ml/min blowing air under 100 ℃, the fuel oil of how much evaluating of settling (carbon deposit) produces the size that carbon deposit is inclined on the 440C stainless steel substrates by measuring, and this method is the generation of analog gasoline carbon deposit on engine fuel nozzle effectively.Intake valve carbon deposit simulation test then is to be that 400 ℃ of low-temperature end are on 120 ℃ the inclination aluminium flake by dripping gasoline continuously in a temperature end, and by observe carbon deposit on the aluminium flake what and estimate a kind of method that carbon deposit produces qualitatively.This method can be simulated the tendency that carbon deposit produces at the intake valve position effectively.
Estimated 90 of blue refining production respectively with above two kinds of methods
#Gasoline and cetane value are 50 diesel oil, and five kinds of prepared prescriptions are added to 90 with 500ppm or 1000ppm
#What of the coke content that produces in gasoline or the diesel oil, the result lists in table 1, table 2 and the table 3 respectively.
Table 1.90# gasoline oxidation test-results
(diameter 22mm, three of the 440C stainless steels of thick 2mm, 300ml gasoline, 100 ℃, 48h)

| Carbon deposit (mg) | 3.87 | 1.88 | 1.81 | 1.59 | 1.53 | 1.60 |
Table 2. diesel oil oxidation test-results
| Sample | Diesel oil (no purification agent) | 1 500ppm fills a prescription | 2 500ppm fill a prescription | 3 500ppm fill a prescription | 4 500ppm fill a prescription | 5 500ppm fill a prescription |
| Carbon deposit (mg) | 4.48 | 2.11 | 2.04 | 1.68 | 1.61 | 1.74 |
Table 3. intake valve carbon deposit analog reslt
| Sample | 90 #Gasoline (no purification agent) | 1 1000ppm fills a prescription | 2 1000ppm fill a prescription | 3 1000ppm fill a prescription | 4 1000ppm fill a prescription | 5 1000ppm fill a prescription |
| Carbon deposit (mg) | Extremely many | In | In | Few | Few | Few |
By the result of table 1, table 2 and table 3 as can be seen, five kinds of purification agent prescriptions that the present invention developed all have good peace and quiet effect.Because fuel oil oxidation test and carbon trumpet have good cognation, and the carbon deposit of intake valve also has good dependency in intake valve simulation test and the testing of engine, thereby five kinds of prescriptions that this invention is developed are all effective gasoline and diesel oil detergent.
