Flex Fuel \ Flexible Fuel Vehicle (FFV), Duel Fuel, Flex Engine & Biofuel.
The flex-fuel vehicle is as same as conventional Spark Ignition Engine Vehicles based on an internal combustion engine. Flex-fuel vehicles or dual-fuel vehicles have an engine capable of operating the functioning of dual-fuel ethanol and gasoline (petrol) with the formed mixture called blended fuel. All fuels contain ethanol to some percentage, it depends on containing ethanol and gasoline (petrol) in the blended fuels according to government policy. It mixes ethanol with other relevant fuels to make them energy productive.
This flex-fuel technology is not new it was first developed in the early 1990s and used in mass production in 1994, Ford Taurus according to data of car bibles by 2017. Now there were more than a 21million flex-fuel vehicles on the road in America. Around the globe ethanol flex-fuel vehicle, approximately 60 million automobile light and heavy-duty vehicles run in the world. by the report of 2018. Countries like Brazil, Canada, America, some European country especially Sweden these countries are the most used flex-fuel and flex engine configurations introduced. Among them Brazil almost 10 to 85 % of flexible-fuel engine/flex-fuel used.
In India current flex-fuel blended ethanol 8.5 % and 91.5% gasoline (petrol) is used in the stored on market fuel pump station. The government of India invest about 40k cores investment for ethanol production to help India achieve its ethanol blending target. Government decide 20 % ethanol-blended fuel achieve the deadline in the year 2025.
Flex Fuel Vehicle (FFVs):
A flexible-fuel automobile is called a flex-fuel vehicle is an alternative fuel vehicle with an internal combustion engine especially a Gasoline Engine configuration or Spark Ignition Engines. The flex-fuel engine normally runs on a mixture of either ethanol or methanol and gasoline (petrol) these fuels are stored in the same common tank. The flex-fuel, the composition of ethanol molecule containing oxygen, allows the engine to complete combustion, thus resulting in lower emissions and reducing to help to environmental pollution and cost-effective as compared to traditional petrol engines.
When we talk about flex-fuel engines it is the same engine only slight change on the flex-fuel system, flex-fuel injection, spark ignition timing and flex-fuel injection in the engine. using higher pressure injectors. Ethanol is difficult to ignite at lower temperature or cold sessions or place it heat up using electronic controlled heating device used in the fuel rail and flex-start technology developed by different car makers adopted flex-start technology on such condition which helps the proper injection in the combustion chamber. This engine is greener and cleaner and environmentally friendly and cost-effective with higher engine outputs as a comparison to conventional petrol engines. In the Indian market TVS, a two-wheeler motorcycles company launched TVS Apache RTR200 E 100 Fuel injection model motorcycle. This is the first Indian motorcycle to complete developed an ethanol run bike in 2019.
What is ethanol?
Ethanol is used for fuel formed which is used for internal combustion engines mainly in automobiles with petrol and ethanol mixture in the fuel injection system in the petrol engine to run the vehicles. The main resource of ethanol is originated from plants. Ethanol has mainly obtained distillation and fermentation from sugar cane and other starch-containing grains.
Pros and Cons of Flex-fuel Vehicle:
These are the main pros and cons of flex-fuel vehicles:
• Less use of fossil
•lower emission level
• Improved volumetric efficiency of the engine.
• ethanol costs less than regular petrol.
• It allows a higher compression ratio and thus increased engine performance.
The fewer cons of the flex-fuel vehicle
• Engine corrode and damage your engine
• Ethanol absorbs dirt easily.
Flex-fuel Vs Bio-fuel Vehicle:
Flex-fuel recently become popular because the world looking up alternative fuel ethanol flex blend fuel one best alternative fuel around the world in the present scenario. It is more environmentally friendly and the cost of production is also less than the petroleum family.
Flex-fuel vehicle and biofuel vehicle is not the same even engine configuration. The Flex-fuel vehicle engine is designed to run on more than one fuel usually petrol mixed with ethanol-based flex-fuel and both fuels are stored in the vehicle same fuel tank. Biofuel vehicle where two fuels are stored in separate tanks and the engine run on the fuel at a time. Biofuel vehicles can switch either petrol Gasoline and other fuel manually or automatically. The most common available fuel in the market for biofuel cars is Compressed Natural Gas (CNG) and another example of biofuel is Liquified Petroleum Gas (LPG) and Hydrogen.
Multifuel vehicles are capable of operating with more than two fuels like fuel using CNG, ethanol and patrols fuel. This year General Motors GM do Brazil introduced the Chevrolet Astra 2.0 with multiplier engine built on flex-fuel technology developed by Bosch of Brazil it power by flex-fuel and Compressed Natural Gas CNG. Similarly, Toyota Brazil announced the development of the first commercial hybrid electric car with a flex-fuel engine capable of running with electricity and a blend of ethanol fuel and petrol. Brazil planning to start production of flexible vehicle and hybrid electric cars for the Brazilian auto market in the future soon.
