“Flex-fuel engines” is an internal combustion engine that can run on multiple fuels and mixed fuels. Usually, a mixture of gasoline and ethanol or methanol is used, and the engine can automatically adjust to each fuel level. Due to the modification of the fuel composition sensor and the correct programming of the ECU, the mixture.
Flex-fuel engines became mandatory to adopt
Flex-fuel engines can run on 100% gasoline or 100% ethanol and are already on the market in countries such as Brazil, the United States, and Canada. India has already used gasoline blended with ethanol, with an initial doping level of 5%, which is currently being implemented.
Earlier this month, the government was closer to its goal of producing a 20% ethanol-gasoline blend (E20) within two years from 2025 to 2023.
Since ethanol is usually produced by fermenting grains such as corn and sugar cane, the mandatory use of flex-fuel engines should also benefit agriculture. It also cut the country’s oil import costs, ranging from Rs 7 lakh crore and Rs 8 lakh crore.
Flex-fuel engines will soon become a necessity in India. The Ministry of Roads and Roads (MDT) announced that it will decide to use flex-fuel engines in the next 810 days.
Gadkari continued: “(The mandatory introduction of flex-fuel engines) will boost the Indian economy because we are a country with a corn surplus, a country with a sugar surplus, and a country with a surplus of wheat. We don’t have a storage room. Those grains are due to the current situation in the country.
In some areas, the price of gasoline exceeds 100 rupees per liter, while the price of ethanol is about 6,062 rupees per liter, which can also save buyers about 3,035 rupees per liter. In addition, the emissions of ethanol-powered vehicles will also be much lower than that of gasoline-powered vehicles.
Cars, given the increasing air pollution in the country, this is of utmost importance. Gadkari said at the 2021 Indian Auto Awards: “I ask everyone in the automotive industry to cooperate with us. Bring flex engines such as the United States, Brazil, and Canada.
Flex-fuel Engine Bike in India
TVS Apache RTR 200 4V
TVS Apache RTR 200 4V is available in the ethanol version. The price is 1.20 rupees (ex-showroom). This price is lower than the updated price of gasoline Apache RTR 4V. TVS Apache RTR 200 Fi E100 is India’s first and currently only engine using ethanol. Series motorcycles.
It costs 1,20,000 (previously a showroom) and is only available in Karnataka, Maharashtra, and Uttar Pradesh. In the 197.75cc single-cylinder engine, the air-oil-cooled E100 uses two-way electronic fuel injection technology.
Flex-Engine Manufacturers in India
Flex engines or dual-fuel engines have become the focus of attention again. At the 60th SIAM Annual Conference, the Minister of Roads, Transport and Highways and the small and medium-sized company Nitin Gadkari once again made OEMs and suppliers aware of the flexibility of engines.
When talking about the government’s willingness to provide a long-term regulatory roadmap for the industry and expand its support for the construction of necessary infrastructure, he believes that the country’s changing advanced technologies can pave the way for India’s transition to global exports. center.
The Minister of the Union stated that the flex engine technology is being tested globally and successfully used by manufacturers. “I urge the industry to adopt flex motor technology. Several companies in Brazil, the United States, and Canada are already using this proven technology.”
Gadkari emphasized that flex engines can help the Indian government achieve two goals: curbi’s world-leading FlexFuel ( FFV) automakers include Ford, Volkswagen, GM, Honda, Nissan, Audi, BMW, Mercedes, Yamaha, and Toyota.
He has also expressed his willingness to find alternative fuels in the past, starting with CNG as an intermediate step. Original equipment manufacturers (OEMs) also support component manufacturers such as Bosch, BorgWarner, and Mahle.
Difference Between Flex Fuel Engine and Regular Engine
The difference between a flex engine or dual-fuel internal combustion engine and a traditional engine is that it can run on fuels other than ethanol and methanol, which are similar to gasoline. Percent of gasoline).
The flex-fuel internal combustion engine system is used to determine the concentration of alternative fuel (ethanol) in the fuel. If the concentration of the alternative fuel is higher than expected, the system will adjust the engine to achieve lean burn.
In order to promote electric vehicle fleets and vehicles that use alternative fuels such as ethanol, the Minister of Transport and Shipping Gadkari also emphasized the need to increase ethanol production in order to switch to ethanol-based transportation.
These engines have nothing to do with flex-fuel, there are flex-fuel engines. These engines can use petrol or petrol mixed with ethanol. Technically speaking, a gasoline engine that can run with CNG is also a flex-fuel engine.
Flex Fuel Engine Problems
Before buying any of these vehicles, you should understand some of the disadvantages of Flex Fuel
Sole Crop Use
Although it is great that corn and sugar can be used to make flex fuels sustainably, there are disadvantages to making flex fuels: plants used for flex fuels cannot be classified elsewhere, which may push up feed prices.
Corn is also susceptible to diseases and weather conditions, such as floods and droughts, which may affect corn prices if the harvest is not good.
Possible Engine Damage
Of course, you want your engine to perform at its best. Unfortunately, ethanol easily absorbs dirt and may corrode and damage your engine, the car bible says.
One of the main problems of driving a flex-fuel vehicle is fuel consumption. Although some experts believe that the performance of flex-fuel vehicles is similar to that of traditional fuel vehicles, other experts believe that their fuel consumption is lower. In other words, it takes 1.5 times as long to provide the same level of energy.
So yes, there is less mileage per gallon when ethanol is used. However, the cost of ethanol is lower than that of regular gasoline, so the savings should be enough to make up for the lost kilometers.
Scarcity of Fuel Stations
Because flex-fuel is not as economical as gasoline, the frequency of operation of gas stations is lower. In fact, only a small percentage of gas stations in the country supply ethanol, although this situation may change as more consumers buy flex-fuel vehicles.
However, modern flex-fuel vehicles can use any combination of gasoline and ethanol, whether it is 100% unleaded gasoline or 85% ethanol. Your vehicle’s sensors will recognize the mixture and make the necessary adjustments.
What are the Benefits of Flex-fuel engines?
Let’s take a look at some of the reasons why you should consider switching to flex-fuel engine.
Cleaner for the Environment
More people today are concerned about the environmental impact of fuel consumption. Ethanol burns cleaner than gasoline, which means that flex-fuel vehicles emit fewer toxic gases into the environment. flex fuels emit fewer greenhouse gases and are therefore more environmentally friendly. Compared with traditional gasoline.
One of the greatest advantages of a flex-fuel vehicle is that it can burn any part of the fuel mixture in the combustion chamber. The car is equipped with electronic sensors to measure the mixture, and its microprocessor adjusts fuel injection and timing.
According to the automobile bible, modern flex-fuel vehicles are manufactured using advanced technologies such as electronic sensors. As mentioned earlier, these technological advancements allow your vehicle to customize how it works, including determining the fuel mix and making any necessary adjustments.
10% to 85% ethanol. With the technology it is equipped with, your car will determine the most effective gear ratio.
Many flex-fuel vehicles use ethanol, which is made from ingredients such as sucrose and corn, which makes ethanol a good substitute for foreign petroleum.
Consumers who force flex-gasoline automobiles acquire tax credit that may substantially lessen or maybe take away their tax obligation.
Although some people may argue that the use of alternative fuel sources will have a negative impact on vehicle performance, it may actually have the opposite effect. flex-fuel vehicles will not lose performance when using E85 fuel. Some of them will produce more torque and power.
Air Pollution and Crude Imports
Gadkari cited the increasing air pollution and the need to cut India’s current crude oil import costs of 7 to 8 trillion rupees, saying, “Air pollution and our crude oil imports are two major issues, so I strongly support fuel pollution, and we are increasing. Ethanol production is stable.
At present, gasoline shipped to India has been blended with about 10-15% ethanol. However, at the current level of production, this is not the standard for all places. The blending value of ethanol requires engine modification, which requires the automotive industry.
Appropriate adjustments and support are recommended. Ethanol is usually made by fermenting crops such as corn and sugarcane, corn, and excess sugar. This gives you peace of mind that flex-fuel is a good solution for our country.
Ethanol / Methanol benefits
Although ethanol has a lower energy content, it is generally better for the environment because these vehicles produce far fewer emissions. In addition, the carbon dioxide emitted by vehicles when burning ethanol is usually offset by the carbon dioxide produced by crops.
However, although there is a surplus of corn and sugar cane in India, careful assessment is needed to ensure that growing these crops as fuel does not distract the country from actual food production, which is already a problem in some countries that use this mixture.
Ethanol and gasoline. Given the huge pressure on electric vehicles, it remains to be seen how the industry will respond to this proposal.
Final Thoughts on Flex-Fuel Engines
The debate about the pros and cons of flex-fuel and flex-fuel vehicles will not fade anytime soon. However, there seems to be a trend to use ethanol as an economical and clean fuel source.
More ethanol refineries are opening, even if you are not ready to switch to flex-fuel vehicles, this is what you need to focus on in the future. Technology is constantly changing, so it is impossible to predict which vehicles have flex-fuel consumption and what progress will occur in the next few years.
You may have driven a flex-fuel car without your knowledge. flex-fuel vehicles are usually no different from other vehicles, but you can find some tips. Insert the fuel injector.
Other vehicles have labels on their doors indicating that they accept Flex-fuel engines. If you own a flex-fuel car, you can now switch to alternative fuel sources without the hassle and cost of buying a new car.
