Forum Opinion: CNG Conversion

[dwtaylorpdx]

Wonder if a nitrous oxide fill station would be adequate.. ??

Nitrous oxide is in liquid form and is at much lower pressure than CNG.

Nitrous oxide is similar to LPG. It is a liquid once compressed.

1 meter cube of natural gas is roughly 1 lilter of gasoline.

10 liter scooba tank, compressed to 200 bars takes 2000 liters or 2 meter cubes or 2 liters worth of fuel.


Now, most ecomodders comsume very little fuel. 3.3 liters per 100 km (the 70 mpg challenge in the other thread) is not too uncommon.

If you have a 50 km commute you would need 1.65 liters of fuel or 1.65 m^3 of natural gas.

That can be stored in a couple of air mattresses if you decide to go not low pressure but ambient pressure NG. It would take up the whole of the back seats and the trunk... but over here it will be 1/4 the price.


I shall try to give it a go when / if I find time. (in a diesel, fumigated to the intake as supplemental fuel)

One more Fiat Strada converted to CNG. Engine is roughly the same fitted to the entry-level Fiat 500.

Notice the CNG tanks under the rear section of the load compartment

Another Fiat Strada with under-body CNG tanks.
