Spotted this article on Reuters.  With the prices of natural gas plummeting in the US due to fracking, it is starting to become viable to install a home fuelling unit to fuel your car from your home's gas supply!   

The cars in the article are purpose built to run on gas, but can you convert a car to CNG (Compressed Natural Gas) in the same way as LPG?  I've seen trucks here that have been converted to CNG.

Looks like it's early days, but interesting nonetheless!!

Could be a great thing.

Only problem I could see with it is that everytime you want to fill up the tank you need a corgi registered gas fitter to do it for you

Also would it need a pilot light to get it going

Perfectly viable some of the staff buses at Gatwick ran on CNG, using vaguely modified diesel engines iirc

Given that lpg can also be used with diesel in diesel engines, I can't see why a spark ignition engine couldn't run on cng guess it would be a simple matter of tweaking the fuel/air mixture and spark timing as required...

Probably no real difference compared to lpg...

[cnj]

one of the large haulage/warehouse operations near us is using cng in some of their new trucks, not sure how many though !

[tigers_gonads]

The Stag 300 lpg ecu's that we use already on the v6's have a setting for cng iirc.
Problem is, without compressing the fuel, your going to need one hell of a big tank to get any sort of useful range which is going to eat into the available space in the car and make it a lot heavier 

Would be nice if you could find a way to compress it into a tank on your property then transfer it to the car when needed

That's exactly what the refuelling units in the article do, only there is no need for a tank as it compresses the gas and transfers directly into the car.

I must learn to read all the article one day

In your garage? Would Jaime's your insurers let you do that?

With the prices of natural gas plummeting in the US

Never going to happen in the UK

[albitz]

Agreed.When Nuclear power stations were first being built we were told it would be so cheap,that it wouldn't be worth the time/expense etc to meter the electricity and send out bills.

[Rods2]

If it happens in the UK then it will bring road pricing that much closer. 

The A14 is being converted for smart messaging and variable speed limits to smooth traffic flow using cables buried in the road. If it is successful then the Government are looking at installing it in a very short time limit all over the UK. Now why would they go to all the expense and do that, or did they just forget to tell us it will be used for very unpopular road pricing. 

[Shackeng]

In the latest issue of 'Air & Space', they have a light a/c flying on CNG!

Wouldn,t trust the cowboy living next to me if he had the gumption to get involved with this.

Induction loops have been used for decades!

M25, M4, M42 - I don't tend to go up north a lot, so these are the ones I know of which use induction loops to monitor traffic density and reduce speeds as and when necessary (or not necessary as it seems).

[05omegav6]

Vosa make pretty good use of the M25 one between junctions 8 and 9
