What is flex fuel car that will run on ethanol and gasoline in India?

    The government has emphasized the need to manufacture flex-fuel vehicles (FAV, FFV) powered by 100% ethanol and gasoline within a year. Its successful technology is available in Brazil and America. The government’s emphasis is also on passenger safety. Under this, Union Road Transport Minister Nitin Gadkari has appealed to all vehicle makers to make it mandatory to install at least 6 airbags in all variants and segments of the vehicle in the interest of passenger safety.

    If ethanol or gasoline is to be used, then such vehicles will have to be launched in the market which will run on flex engine. Such vehicles are made and run in many parts of the world. Its manufacturing has not started in India yet. The FAV is powered by an internal combustion engine that runs on gasoline, a mixture of gasoline and ethanol. In such vehicles, up to 83% ethanol can be mixed in the fuel.


    The engine of C vehicles has a ‘One Fuel System’ and the components of the engine are the same as in the engine of a normal gasoline car. Some changes are made in the fuel pump in the engine of a gasoline car so that the chemical reaction of ethanol can take place and it can get energy to drive the vehicle. The control module of the engine is also modified so that the oxygen of ethanol can be adjusted correctly.

    Features of Flex-Fuel Cars

    • To start the engine, the battery is used to supply power to the vehicle’s electronics system and accessories.
    • The Electronic Control Module (ECM) controls the ECM Fuel Mixture, Ignition Timing and Emission System in ECM-Flex vehicles. Also monitors the operation of the vehicle, prevents damage to the engine and informs if there is any problem in the vehicle.
    • Exhaust System- The exhaust system extracts the gas from the tailpipe of the vehicle. It has three types of catalysts which reduce the pollution caused by the engine.
    • Fuel Filler – A nozzle attached to the fuel dispenser which helps in filling the fuel in the tank of the vehicle.
    • Fuel Injection System – This system helps in sending fuel to the combustion chamber of the engine so that the oil is burnt and energy is generated from it.
    • Fuel line – This is a metal tube or flexible hose that helps to supply fuel from the tank to the fuel injection system of the engine
      Fuel Pump – This is the pump that sends fuel from the tank to the engine’s fluid injection system through the fuel line.
    • Fuel tank – contains a mixture of ethanol or gasoline. This tank stores fuel to power the vehicle and generate power.
    • Internal Combustion Engine- This engine works to send oil to the combustion chamber. Here the fuel mixes with the air to produce a spark, for which a spark plug is installed in the engine. This burns the oil and gives energy for the vehicle.
    • Transmission – The transmission of a vehicle sends mechanical power from the engine or electric traction motor to the wheel of the vehicle so that the wheels turn.
