CNG conversion for the 6.2L?????

CNG cylinders

The thing about Compressed Natural Gas (CNG) is that even under 3000 psi, it remains a gas at normal temperatures. This is because it is mostly methane which is the lightest form of hydrocarbon. Propane is much more dense and liquifies under a tank pressure of only a couple hundred psi. Octane (gasoline) is many times more dense and is a liquid. A typical CNG cylinder might hold 18 gallons of water but pressurized to 3000 psi would supply the same fuel as 4 1/2 gallons of regular gasoline. Two cylinders stacked at the front of the box gains you 9 gallons (typical max setup). Even if you have to use a little gasoline every day, remember that the first 9 gallons is cheap Uncle Sam's fuel and that other crap is expensive Saudi or BP stuff. As for the fill-ups being variable, it matters what temperature it is when you fill up. Remember I said that it is always a gas. That means that 3000 psi at 70F is the same as 2000 psi at 0F. And since the CNG fuel gauge is a pressure gauge, it looks like you drive away with less fuel when its cold out because the station doesn't give you a full 3000 psi at 0F so you can't then park in a warm garage and have the 3600 psi relief valves start blowing overnight.

Ok I just got some new info on CNG for 6.2L. Here is the link hopefully people can see it due to the 2 raptors pictured on it but if not i'm going to copy the text to the post so you can at least read it.

PowerFuel CNG - EPA-Certified with Lowest Emissions



On March 5, 2012 PowerFuel CNG Systems received EPA certification for its pioneering CNG fuel option on the Ford 6.2 liter engine. Uncompromised Ford performance is now offered with integrated CNG on Super Duty F-250 and F-350 trucks.


Ford truck owners can now take advantage of CNG on a platform that is fully-integrated with the Ford OEM powertrain system, with a driving experience that is indistinguishable from gasoline performance.

In addition to uncompromised CNG performance, the PowerFuel system offers record-breaking overall vehicle emissions reductions for light duty trucks, as well as Greenhouse Gas (GhG) reductions that bring CNG emissions for this class of vehicles to a historic low.

The company is responsible for innovating the application of a Ford Powertrain Control Module (PCM) for CNG. The software and calibration were developed by a Ford Qualified Calibration Modifier (QCM) and implemented with full authorized access to Ford's powertrain controls. This degree of integration enables complete control of all sensors and actuators including those associated with the natural gas system, and the Ford patent-applied-for control architecture minimizes the wiring impact. Because of the OEM-system integration, CNG diagnostic capability at any Ford dealership is now also made possible for vehicles with the PowerFuel system.
[Truck]
Customers should order their trucks at their preferred dealership with the gaseous fuel prep option. Ford's 3-year or 36,000 mile bumper-to-bumper warranty applies, as does the Ford Powertrain warranty of 5 years or 60,000 miles. Furthermore, when a PowerFuel CNG prep truck is converted, the Ford basic engine warranty of 5 years or 60,000 miles is retained because the conversion meets Ford's Q185 standard for gaseous fuel conversions. As a Ford-certified Small Volume Manufacturer (SVM), PowerFuel warrants the emissions-related components for 8 years or 80,000 miles.

The system is EPA certified for either CNG-only or hybrid (bi-fuel) options for 2011 or 2012 model years.

With the PowerFuel system's EPA certification and its introduction of new standards of performance and reduced emissions, the company is ushering in a new era of CNG technology with Ford light-duty trucks at the forefront.

The raptor is on their main page so looks promising for sure!

Been there, done that...

Not saying CNG conversion is a good or bad idea, just sharing my experience...

I worked two years at a gas utility that ran dual fuel Suburbans and station wagons. They had four large high pressure tanks in back, with steel straps to keep them in place in case of a wreck. The large utility trucks trickle fed overnight, but the smaller vehicles I took used the quick fill. Every morning, the first thing we did before heading out for the day was to stop at the 7000PSI fill station (these were 7K PSI, as the gas company was experimenting with techniques to get longer run times). The pressure fitting was huge, and you had to remember to vent the line after filling, before pulling the ring on the quick disconnect. (One guy forgot one morning, and lost his private parts as it rocketed backward). The four tanks would last us most of the day, and around late afternoon the truck would start coughing, and we would flip a switch to revert back to gasoline. When running on CNG, the trucks had zero spare power, but it was good enough to keep up with traffic on paved roads. Sometimes on backroads, we would have to switch back to gasoline when more power was needed.

What year was this and what year were the suburbans?

 

[CNG Raptor]

I have had my '11 Raptor on CNG for about 22k, with no issues so far. My 24 GGE (gasoline gallon equiv.) tank takes up the same space as a toolbox (21"x60")
I can drive 250-300 miles on CNG before switching back to gasoline.

I have removed the fuel system in preparation of a Whipple supercharger with an upgraded CNG fuel system, as well as a more versatile alternative fuel controller. It will take 16 220# Bosch injectors to get enough fuel into the engine, and the same fuel controller will also drive a water/methanol system to keep temperatures down under boost.

It will be one hell of a truck once its done.

I will post some updates on project CNG Raptor v2.0 once i get things rolling.

So on one side of the frame is the gastank
What is the reason not to mount a cng or lpg tank on on the otherside
Out of sight. And out of the bed
Also put on inthe spare tire a tank and u can store the ~200liters as well

Because the tank is quite large. There are smaller ones that would fit, but would only hold enough fuel to go 50-60 miles.

So you're not able to combine 3 or more smaller tanks ??
The biggest tank on raptor is 36gallon gasoline aka 133liter

Ur tank was 20x50 aka ~4000cubic inch aka 65.000cc or 65 liters
So unless my math is wrong ( and it can as i do it without a calculator
U should be ae to get same / more space for cng/lpg

CNG Raptor....some more pics:

Wow that is like a plubbes nightmare under the hood
But something i need to look into more
As gas here is atm €1,80 a liter
And cng or lpg is something we serieusly need just to get away from taxes and ridicules gas prices

Do you have to pump any kind of oil into the CNG system?
