At how many Pa is CNG stored? --CAJ 18:06, 27 April 2006 (UTC)

[edit] Efficiency compared to MCFC and electric mobility

An ICE has a low efficiency in a car. Since compressed natural gas cars have only a short range, they are mostly used in city traffic, where the ICE has an even worse efficiency.

When the gas is instead used in a Molten-carbonate fuel cell with Steam turbine behind to produce electricity with 64% efficiency, a Plug-in hybrid or Battery electric vehicle could drive 4 times more km with the same gas than an ICE car. --Pege.founder 06:34, 2 August 2006 (UTC)

[edit] SuperGirl uses CNG as a weapon?

Unity_(Superman:_The_Animated_Series)

The female of the alien Unity was killed when Supergirl threw a can of compressed flammable gas, possibly Compressed_natural_gas, at it, which embedded into the creature, she then ignited the gas canister with her heat vision, which exploded in a giant fireball, blasting the creature apart.


I think you should discuss this “super girl” subject elsewhere. This is not appropriate to this article.Ragingmaster 17:20, 18 October 2007 (UTC)

[edit] CNG is less power than gasoline?

Is it true that CNG is weaker than gasoline. It's quite a common rumor; I'm not sure if it's true. By weaker I mean: slower acceleration, less towing power, etc. If this is true, why is CNG used in transit? —Preceding unsigned comment added by Zybez (talk • contribs) 02:16, August 29, 2007 (UTC)


TOOL!!! who ever wrote this —Preceding unsigned comment added by 64.180.146.23 (talk) 03:03, 12 October 2007 (UTC)


It is much cheaper then all other kinds of common fuel, and it is environmentally superior, emitting considerably less pollution to the atmosphere. And yes, it really is “weaker” then other kinds of fuel (5% less power to de vehicle), but this is more a matter of technology than of the fuel itself. I believe that, with time, the engines will adapt better to this kind of energy. Ragingmaster 17:02, 18 October 2007 (UTC)


In the same engine, CNG will indeed produce less power. This is due to the fact that an internal combustion engine's power is determined, in a large part, by how much air it can get into the process (engine capacity). Natural Gas requires more oxygen per unit energy produced than gasoline, therefore, in the exact same engine, it would produce less power running CNG. However, in an engine designed for CNG, this can be made up for with more aggresive timing and higher compression, due to the high octane rating of CNG (130+).

[edit] Natural Gas automobile

I have read the articles on previous pages, however what I want to know is: I have a LPG converted panelvan, can I use the same set-up with CNG eg gas tank and carburator/injecters and refuel from my house mains gas supply with an appropriate compressor? —Preceding unsigned comment added by 210.9.221.28 (talk) 11:37, 4 May 2008 (UTC)

The short answer is no. Your LPG storage tank could not be used to hold CNG, as it is nowhere near rated for the high pressures CNG requires. CNG Cylinders are the most expensive part of a CNG conversion, as they are rated for storage of 3600#. Also, much of the regulation components would need to be replaced, as they are designed for dealing with the liquid stored LPG. CraziFuzzy (talk) 09:22, 7 June 2008 (UTC)

[edit] America?

This article covers Canada, Europe, South America, and Asia, but not the United States. I am not knowledgable about this topic, but perhaps someone who is could add such a section. —Preceding unsigned comment added by 217.85.118.228 (talk) 08:01, 6 June 2008 (UTC)

  • Started United States section. Feel free to elaborate, as I just started with a summary of current situation. CraziFuzzy (talk) 08:34, 8 June 2008 (UTC)
