Abstract
- For studying the effect of methanol gasoline on the corrosion and mechanical properties of rubber parts in vehicles, an immersion test of several currently used rubber parts in methanol gasoline is conducted to observe the variation relationship between the deformation and acting force of rubber parts and to analyze the cause of change of rubber parts after immersion. The results show that the black precipitate of solution, in which rubber parts are immersed, contains carbon black; the rubber tube made of NBR + CR or FKM + braided layer + ECO are rather significantly subjected to the effects of methanol concentration of methanol gasoline, leading to marked deterioration in mechanical performance; multi-layered PA12 is also greatly subjected to the effects of methanol but is not sensitive to the proportion of methanol added; while methanol has no apparent effects on the oil seals for intake and exhaust valves.
