Automotive High Clean Fuel Corrosion Research

Abstract

The high clean fuel is a mixture of 60 % of methanol and 40 % of the modifier, the modifier is a mixture of oleic acid, petroleum ether and other petrochemical products. Experiment with different proportions of clean fuel and petrol mixture was performed for the electric fuel pump into the corrosion test. The results show that the mixture without adding antioxidants, copper corrosion is quite dramatic. Gradually increase the amount of antioxidant, make it meet the eligibility criteria. Among them, when the antioxidant content of No. 1 mixed liquor is 90 ppm, it meet the test standard ealier; when the antioxidant content of No. 2 mixed liquor is 150 ppm, all the additives except No. 2 additive meet the test standard. When the antioxidant content of No. 3 mixed liquor is as high as 200 ppm, it will meet the test standard. The result of present experiment shows that there is no mercaptan in the mixed liquor of test.
