1.	Due to which alcohol corrosion of rubber and aluminum parts occur?(a) Methanol(b) Ethanol(c) Propanol(d) ButanolThe question was posed to me in a job interview.This intriguing question originated from Alternative Fuels topic in section Fuels, Intake System & Leakage Preventers of Automotive Engine Design
Answer» The CORRECT option is (b) Ethanol Explanation: CORROSION of rubber, magnesium, and aluminum parts occurs at HIGHER ethanol percentages, and also it is ELECTRICALLY conducting, this can cause a problem with some electric FUEL pumps.
