Q. Consider the following statements regarding “Flex Fuel Vehicles”:
1.Like traditional vehicles, flex fuel vehicles do not have an internal combustion engine.
2.Unlike electric hybrid vehicles, no bulky parts need to be added to the basic gasoline vehicle architecture.
Which of the statements given above is/are correct?
Explanation: Like traditional vehicles, flex fuel vehicles have an internal combustion engine, but instead of regular petrol, it can run on blended fuel — petrol with ethanol or methanol.
- The ethanol mix can vary between 20% and 85%.
- The vehicle has additional sensors and different programming of the engine control module to assess the blend of the fuel and adjust accordingly.
Unlike electric hybrid vehicles, no bulky parts need to be added to the basic gasoline vehicle architecture. Upgrading existing vehicles to run on high blend of ethanol fuel, however, is possible but expensive and not considered feasible.
