What is a flex-fuel module?
Flexible fuel vehicles (FFVs) have an internal combustion engine and are capable of operating on gasoline and any blend of gasoline and ethanol up to 83%. The engine control module (ECM) is also calibrated to accommodate the higher oxygen content of ethanol. Learn more about flex fuel vehicles.
Is there a difference between E85 and flex-fuel?
While E85 gas costs less than regular gasoline at the pump, the decrease in miles per gallon makes it more expensive when driving. Despite the lower miles per gallon, flex-fuel vehicles often put out more torque and more horsepower when running on E85 instead of regular gasoline.
What’s the difference between a flex-fuel engine?
The main differences between the two lie with the engine and fuel system. The internal combustion engine of a flex-fuel vehicle is designed to run on more than one type of fuel — usually gasoline plus ethanol or methanol fuel, all of which are stored in the same tank [source: Chapman].
Can flex fuel cars use regular gas?
The benefit of a modern flex-fuel vehicle, though, is that you can use any combination of gasoline and ethanol, whether it’s 100 percent unleaded gas or 85 percent ethanol. Your vehicle’s sensors will detect the blend and make the necessary changes.
What do you need to know about flex fuel sensor?
Flex-Fuel Sensor – FUEL-IT! Two options to choose from: *Note: An ethanol analyzer must be used in conjunction with the ethanol sensor to read your ethanol content. *Ethanol sensor readings are based on the gasoline content of your fuel. Fuel that has been contaminated can generate a false ethanol reading.
Is the flex fuel vehicle the same as bi fuel?
Flex fuel vehicles, as duel fuel vehicles, have an internal combustion engine capable of functioning with a mixture of fuels. Flex fuel vehicles are therefore not the same as bi-fuel vehicles, which have separate tanks for each different fuel type they use.
How does a flex fuel car engine work?
Get answers to frequent questions about flex fuel cars, how a flex fuel engine works, and the pros and cons of flex fuel vehicles. Flex fuel vehicles, as duel fuel vehicles, have an internal combustion engine capable of functioning with a mixture of fuels.
What are the advantages and disadvantages of flex fuel vehicles?
Although the advantages and disadvantages of flex fuel vehicles will be debated for some time to come, one of the most popular fuels for these vehicles, ethanol, is finding favor with many in power positions. More ethanol refining plants are requesting permission to develop additional facilities.
How does a flex fuel control sensor work?
Following the wiring guide that comes with the sensor, we wire up +12V, signal and sensor ground to the ECU wiring harness. Because flex fuel sensors are a frequency based input, this sensor needs to be wired into a digital pulsed input or DPIs on the ECU.
How does flex fuel control work in Haltech?
The simplest way of achieving this is to go into the MAIN SET UP window and click on the FUEL tab, here we can select the fuel type – select “Flex Fuel”. This tells the ECU to look at the flex fuel sensor and automatically calculate the additional fuel required to provide the engine to meet the target air/fuel ratio.
What’s the difference between flex fuel and regular gas?
The main differences between the two lie with the engine and fuel system. Before discussing them, let’s take a quick look at what fuels a flex-fuel vehicle. Flex-fuels can run on regular gas, various ethanol blends and other types of fuel [source: Bionomic Fuels ].
Why is ethanol used in flex fuel control?
It’s no secret ethanol based fuels are becoming more and more popular with performance enthusiasts and for good reason. Ethanol has a high octane rating, it’s affordable, it’s renewable and it’s clean-burning.
