How Do Flexible Fuel Cars Work Using Ethanol?

Flex-fuel is an alternate fuel that combines regular petrol with either methanol or ethanol. This fuel combination is stored in exactly the same tank of fuel and is employed by the engine as a blended fuel. This 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 can 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 can be adjusted to feature more petrol to prevent cold starting problems in cold areas.

Unlike CNG cars, flex-fuel requires minimal modifications to the fuel system and engine to effectively utilize the fuel. This means flex-fuel compatibility must be factory-engineered and can't be fitted in the after-market. The changes to the fuel system and engine are meant to make the engines resistant to ethanol, which may be corrosive to engines. For consumers, this implies very little change in the way they drive, which could help mass adoption of the fuel at a rapid rate.

What Is Flex Fuel?
Flex Fuel, also called E85, is just a fuel mixture made of gasoline and between 51-83 percent ethanol. E85 can only just be found in Flex Fuel vehicles which have been specifically designed to use this sort of fuel.

What Is Ethanol?
Ethanol is undrinkable clear grain alcohol harvested from starchy and sugary plants such as for example corn, sugarcane, sorghum, barley, and others. In the U.S., a majority of ethanol originates from corn fermentation. Ethanol is known as a renewable fuel since it is made from biomass, or plant matter, as opposed to fossil fuels.

A Flex Fuel Vehicle (FFV) is a vehicle that's been specifically made to drive using E85 fuel. FFVs are much like common gasoline vehicles, apart from a few altered parts, and many FFVs can optionally run using regular gasoline making them easier to reside with day in and day out.

As an example, the Ford F-150 is available 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 dime coating inside diameter of the lines. There is also higher volume fuel pumps and fuel delivery modules with aluminum rotors compared to composite rotors.
