Embodiment 1

[0036] A bio-gasoline detergent synergist, characterized in that:

[0037] Contains Rhodococcus erythropolis T7-3 and Serratia marcescens CGMCC4074.

[0038] The preparation method of above-mentioned biological gasoline cleaning agent, its step is as follows:

[0039] (1) Inoculate Rhodococcus erythropolis T7-3 and Serratia marcescens CGMCC 4074 in glycerol cryopreservation tubes, pick 3 rings and transfer them to 80mL LB shaker flasks, at 65°C, 120rpm , shaking culture for 24h, and finally configured to prepare 10 8 CFU / ml bacterial solution, and then mix it evenly according to the mass ratio of 1:1 to become a mixed bacterial solution;

[0040] (2) Gasoline induced culture:

[0041] Transfer to gasoline induction medium, inoculum amount 10%, shaking culture for 24 hours;

[0042] The induction medium:

[0043] 1% gasoline, 1.5% yeast powder, 1% sucrose, 0.5% trehalose, 0.1% sodium dihydrogen phosphate, 0.1 potassium dihydrogen phosphate, pH 7.2;

[0044] (3) After indu...

Embodiment 3

[0068] The modified clean gasoline obtained in Example 1-2 was used as the experimental group. The unmodified 93# gasoline was used as the control group.

[0069] Use BYD 476ZQA gasoline engine to compare the combustion chamber deposit quality and fuel consumption rate of each group.

[0070] Experimental conditions: each experimental group is equipped with 50 liters of 93# gasoline, at room temperature 20 ℃, air pressure 101.7kPa, humidity 60RH%, start the engine, enter the real-time measurement and control system, adjust the engine speed to 2000r / min, load In the working condition of 75%, after 100 hours of operation, the deposit quality and fuel consumption rate of each group of combustion chambers were compared. Each experiment was repeated 3 times. The specific test results are shown in Table 1.

[0071] Table 1 Results of combustion chamber deposits and fuel consumption rate of each group

[0072] Combustion chamber deposits / mg Fuel consumption rate / g(kWh) ...

Embodiment 4

[0075] The bio-gasoline detergent synergist obtained in Example 1 and Comparative Examples 1-3 is used as an experimental group, and Shell SL5W / 30 is used as a comparative example to directly carry out the four-ball test abrasion test of gasoline engine oil to compare the lubricating effect of the bio-detergent . The test data are shown in Table 2:

[0076] Table 2 Four-ball test wear scar test

[0077] Wear spot diameter (mm) Example 1 group 0.657 Comparative example 1 group 1.813 Comparative example 2 groups 1.636 Comparative example 3 groups 1.798 control group 0.389

[0078] From the data analysis of the wear spot diameter test: the control group has the worst effect. Compared with the comparative example group, the diameter of the wear spot of the example group is obviously reduced, and the wear resistance is increased. Although relative to the SL5W / 30 lubricating oil, there is a certain gap between the effects of the embod...

Abstract

The invention relates to a biological gasoline detergent synergist. The biological gasoline detergent synergist is characterized by containing Rhodococcus erythropolis T7-3 and Serratia marcescens CGMCC 4074. Even shaking is performed before use, and cold storage is the best. A use method of the biological gasoline detergent synergist comprises the following steps: the biological gasoline detergent synergist is mixed with 93# gasoline and a 2% lyxose aqueous solution according to a mass ratio of 1:100:150, a reaction is carried out for 36 h at 50 rpm vortex stirring, standing is performed for2 h or more to wait for oil-water layer separation after the reaction is completed, then a separating funnel is used to collect the oil layer, and the oil product is a modified clean gasoline.

Description

technical field [0001] The invention relates to the application of microorganisms in the field of clean energy, in particular to a bio-gasoline detergent synergist. Background technique [0002] More and more stringent energy-saving and environmental protection requirements have always been the goal and driving force for the continuous development of the automotive industry. Since the 1980s, electronically controlled orifice fuel injectors have been widely used in automobile engines in foreign developed countries to replace the original carburetors, which can reduce harmful emissions and fuel consumption. However, the working conditions of EFI engines are more stringent, and gasoline is prone to form deposits such as paint film and carbon deposits on engine nozzles, intake valves, combustion chambers, etc., resulting in deterioration of the combustion process and increased emissions and fuel consumption. Gasoline detergent is very effective in controlling engine deposits, s...
