A flexible fuel vehicle (FFV) or dual-fuel vehicle (also known as a flex-fuel vehicle) is an alternative fuel vehicle with an internal combustion engine that can run on more than one fuel. Commonly gasoline combined with either ethanol or methanol, and both fuels are kept in the same common tank. Flex fuel vehicles (FFVs) are automobiles with an internal combustion engine that can run on gasoline or a mixture of gasoline and ethanol up to 83 percent. FFVs feature a single fuel system, and the majority of the components are the same as in a traditional gasoline-only vehicle.

To compensate for the varied chemical characteristics and energy content in ethanol, several ethanol-compatible components, such as adjustments to the fuel pump and fuel injection system, are required. The engine control module (ECM) has also been tuned to account for ethanol’s greater oxygen level.

The Most Important Parts of a Flex-Fuel Vehicle

Battery: The battery is responsible for starting the engine and powering the vehicle’s electronics and accessories.

Fuel injection system: This system injects fuel into the combustion chambers of the engine to ignite it.

The electronic control module (ECM): regulates the fuel mixture, ignition timing, and emissions system, as well as monitoring the vehicle’s operation, protecting the engine from abuse, and detecting and troubleshooting issues.

Fuel line: Fuel is transferred from the tank to the engine’s fuel injection system via a metal tube or flexible hose (or a combination of these).

Fuel pump: A pump that uses the fuel line to move fuel from the tank to the engine’s fuel injection system.

Fuel filler: To fill the tank, a nozzle from a fuel dispenser is attached to the vehicle’s receptacle.

Fuel tank (ethanol/gasoline blend): This tank holds fuel to power the vehicle’s engine.

Exhaust system: The exhaust system is responsible for transporting exhaust gases from the engine to the tailpipe. A three-way catalyst is used in the exhaust system to reduce engine-out emissions.

Internal combustion engine (spark-ignited): In this arrangement, gasoline is pumped into either the intake manifold or the combustion chamber, where it is mixed with air and ignited by a spark from a spark plug.

Transmission: The transmission is responsible for transferring mechanical power from the engine and/or electric traction motor to the wheels.

What was the very first flex fuel vehicle?

If you want to go really technical, the “very first flex fuel vehicle” was Henry Ford’s Model T, which was introduced in 1908. The vehicle had a carburetor that could be adjusted. A car could run on ethanol, gasoline, or a combination of the two. Fast forward to the present day, and the first FFV was the Ford Taurus, which was produced in the 1990s. The Taurus can run on either E85 or ordinary gas with no problems.

What Are the Differences Between Flex-Fuel Vehicles and Conventional Vehicles?

Flex-fuel cars have a very similar appearance to conventional vehicles. The sole difference between a flex fuel car and a conventional vehicle is that it can run on either ordinary gas or E85. Which is a blend of 85 percent ethanol and 15% gasoline. According to reports, car manufacturers began creating flex fuel vehicles in 1988, when the Alternative Motor Fuels Act was passed by legislators. The statute provides tax benefits for the manufacture of alternative-fuel automobiles.
