Cinversion of petrol engine to CNG (compressed natural gas )

[Zafar]

I am having morris minor 1000, 1965 model. Still in running condition.
In Pakistan we have plenty of CNG filling stations. Is possible to convert the engine from petrol/CNG by placing an appropriate CNG kit.

Thanks & Regatds

if it helps its known as LPG in this country.

I would be interested in doing this too, but dont know how!

i have seen a car at a that was lpg and they converted it back,madness lpg does burn a bit hotter but it burns cleanly and does not produce the carbon,so the oil stays clean for ages,less oil changes.it is an expensive conversion,it will take a lot of miles to recoup the costs,but the lpg is half the cost of petrol,its an intresting one.i dont know all the tech stuff,this is based on what people have told me.

LPG is not CNG!! LPG = Liquified petroleum gas (propane/butane mix). CNG = Compressed methane. It doesn't go liquid (at normal temp) - just stored as a compressed gas. So bulk density is not great. ie - Big tank needed and frequent refills.
If CNG is common in Pakistan - I'm sure there will be plenty of local companies who can do the conversion for you!

A friend had a CNG Vauxhall Combi van but the tank wasn't certified to the pressures of the local filling sations - mainly for lorries.
I spoke to a local LPG specialist I know and he said easy to convert to reconvert LPG. Obviously all the CNG components would need removing and LPG items installing but the were basically the same - just different specs.
With that in mind I'd say if you can convert a Minor to LPG then CNG is also viable.

BTW when my mate bought the CNG van he also looked at a pump (approx £1000) that allowed you to fill up with gas at home but it'd take virtually all night.

You can have an LPG tank at home - but you would need to rent it - and have a transfer pump (they are quick - just a few minutes - same as at any Filling Station) - the gas may be slightly cheaper but you MUST pay fuel duty on it! Or be locked up for life!

You can have an LPG tank at home -

Which requires council permission as a friend found out when he wanted to change from solid fuel to LPG powered central heating.

Indeed it likely will! Quite a fire risk - as well as obvious visual nasty. I know of one that is buried in the house garden - only the fill pipe and draw-off pipe sticking up!
