Q. With reference to Flex-Fuel vehicles, consider the following statements::
1.It is an alternative fuel vehicle that has an internal combustion engine designed to run on more than one fuel.
2.The more ethanol a flexible-fuel vehicle uses, the better its fuel efficiency becomes.
3.The fuel system in an FFV is designed to handle the different properties of gasoline and ethanol blends.
Which of the statements given above are correct?
Answer: C
Notes:
Explanation –
Statements 1 and 3 are correct. Flex-Fuel vehicles is an alternative fuel vehicle that has an internal combustion engine designed to run on more than one fuel. The fuel system in an FFV is designed to handle the different properties of gasoline and ethanol blends.
Statement 2 is incorrect. Ethanol has a lower energy density than gasoline, so using more ethanol in a flexible-fuel vehicle will actually decrease its fuel efficiency. This is because the engine will need to work harder to burn the ethanol, which will use more fuel.
