How Do Flexible Fuel Cars Work Using Ethanol?
Flex-fuel is definitely an alternate fuel that combines regular petrol with either methanol or ethanol. This fuel combination is stored in the exact same tank of fuel and is utilized by the engine as a blended fuel. This really is on the other hand to CNG fuel systems which store petrol and CNG in separate tanks and are utilized separately by the engine. The ratio of ethanol to petrol may be adjusted to be any combination from full petrol to full ethanol to everything in between. The absolute most commonly used flex-fuels use 85% ethanol and 15% petrol but this ratio could be adjusted to feature more petrol in order to avoid cold starting problems in cold areas.

Unlike CNG cars, flex-fuel requires minimal modifications to the fuel system and engine to effectively use the fuel. What this means is flex-fuel compatibility needs to be factory-engineered and can't be fitted in the after-market. The changes to the fuel system and engine are meant to help make the engines resistant to ethanol, which can be corrosive to engines. For consumers, what this means is very little change in how they drive, which can help mass adoption of the fuel at a rapid rate.
What Is Flex Fuel?
Flex Fuel, also referred to as E85, is a fuel mixture made from gasoline and between 51-83 percent ethanol. E85 can only just be utilized in Flex Fuel vehicles that have been specifically designed to make use of this type of fuel.
What Is Ethanol?
Ethanol is undrinkable clear grain alcohol harvested from starchy and sugary plants such as for instance corn, sugarcane, sorghum, barley, and others. In the U.S., most ethanol arises from corn fermentation. Ethanol is recognized as a renewable fuel as it is manufactured out of biomass, or plant matter, as opposed to fossil fuels.
A Flex Fuel Vehicle (FFV) is really a vehicle that has been specifically made to operate a vehicle using E85 fuel. FFVs are much like common gasoline vehicles, apart from a few altered parts, and many FFVs can optionally run on regular gasoline making them easier to call home with day in and day out.
As an example, the Ford F-150 can be obtained with Flex Fuel powertrains, the 3.3-liter and 5.0-liter engines. To allow for E85, Flex Fuel F150s have unique fuel lines with a nickel coating inside diameter of the lines. They likewise have higher volume fuel pumps and fuel delivery modules with aluminum rotors compared to composite rotors.
