CNG information !

Hi
Not strictly Froggie related but just as applicable to them.

Anyone here know anything about running cars on natural gas. The busses do it. Lots of cars OS are said to do it. I and lots of other city people have NG laid on at home and the price is right. Honda in the US made a model supplied with a home filling station at one stage. However there is no information about using CNG here. Could it be, we would rather sell it all overseas at bargain prices and import expensive petrol. More profit.

I believe there is a firm in Melbourne that is promoting it. They sell all the required bits. They even have a public refueling station. Seen them or heard anything about them. I saw a reference to a Falcon model that was factory fitted for CNG years ago, that's news to me.

Aussie Froggers are an enquiring and inventive lot, so I thought it was worth tapping that resource.

Molerpa is the person to speak to this.

He is a consultant on CNG systems/ conversions I believe.

Shoot him a pm.

I have no idea about that!

I think is not thaaaat much to be calling me a guru, or a consultant...


I just do barbacue... all over the world.

Well... not a guru, but if there is anything I can do to help you, just let me know. (In fact, we have a contact there which is OES o AOES... don't remember.. who used a few of our systems, but as they didn't care to much about sales, the company never sent me there...

AAAAAaaaaaaaaaaaaand... shadowpucci works with me... technically, should know the same (or even more... my dear paddawan)

Now come clean and tell the world what sort of pressure you run in those two cylinders in order to cram enough energy into car to make it viable???

There is no way i would want to be sitting in front of those two missiles.

Vapour pressure for LPG is around 1500kpa (?), and I'm guessing to store the same energy in the same space, the natural gas pressure is probably 8 times that.

Remember back when diesel was so much cheaper than petrol? The comparative cost to manufacture hasn't changed, but what the market is prepared to pay for it has. If the NG thing takes off (other than into orbit through a failed pressure storage system) then the price of NG will go up to what ever level the market will bear with no reference to the real cost of production.

Having said all that, it is still a very clean fuel. What we should be doing is pushing the community, government and industry into replacing coal fired power generation with gas fired units. If we don't have significant investment in the sector in Victoria in the next 10 years, we are going to be in trouble anyway. By then, our major power plants will be reaching the end of their design life. You can't build 1000MW of power generation overnight, the investment needs to start soon.

Off my soap box now, but would be interested in what pressure the vehicle systems run, and what volume of storage you require to manage a 500km range.

My 306 just did 830km on 55 litres of unleaded.

WoW !

Hi
Well that's a good 'picture' of the potential Molpera, Thanks. Do you work for a particular company that sells BBQs/CNG systems or suppiers or ?? Or a travel company(just envious)

Do the South African Porches fit gas to save money:joker:

Having played around pressure vessels a bit, racing 405, I would be happier with the HP tanks than a plastic petrol tank in an incident. Neither is a big risk in my opinion and I guess the stats back that up. Fuel tanks only 'blowup" in Hollywood, so minimise your risks and do not go there.

The CNG place in Melbourne is here; Note the offer of free fuel for a year !!!!

I was hoping for someone who had direct contact with them or the equipment in Australia.

CNG is much more safer than LPG, by a few things.

a- weight (always will vanish, reaching highest level)
b- tanks are submitted to several tests, cannot blow up unless is an illegal recipient. 200 bar is normal working pressure. In USA are using 250... at 290-320 have the Pressure Relief Device, and around 470 are exploding. Every 5 years an hydraulic test has to be done, at 1.5 times working pressure (300bar for the 200 normal pressure cases) and the deformation is measured. If not accomplish certain level, tank is destroyed.

I had all of my cars runing on CNG. Octane level is higher than petrol, (around 127 octanes) which allows you to increase Compression Ratio and install a turbocharger without plenty of problems that you might have on petrol... for example an old fox (jetta) 1990, 1.8 engine, 10:1 CR and 20psi turbocharger....
