LPG system confusion.

Post by **high_tower** » 17 Jun 2008, 13:40

Afternoon,

I've been looking at installing a LPG system to my 2.0l Aircooled. However i've only ever fitted lpg to a liquid cooled engine. just looking at how the systems people have fitted to their vans heats up the vaporizer part of the system.

I've read a few 'ideas' online and would like to know what way works best. I've read of a way of tapping the exhaust and circulating exhaust gases to heat the vaporiser.

What way is the most common/practical/safe??

a exhaust probe is the common way with the aircold T25 ,

some have tried with other methods, but ive never seen anyone using anything other than the probe method.

Is this an Administrative Error

the probe is inserted into the silencer, and heats up the gas which is piped through a brass block at the end of the probe, outside the exhaust sliencer, adding just enough heat to stop the icing..........

i have never seen any of the alternatives being used, only heard about them, or seen pictures - IoMSi had a go with heating water to heat the LPG some years ago on his "GreenMonster" van back on the IoM, but like i say, the exhaust probe seems to be the way to go........ perhaps someone with one will take you a picture, i dont have any pictures of them, although i have fitted several.......

a picture of a set up would be ideal.

cheers for the help

Sorry to sound like a pest. So are people dispensing completely with vaporisers? I've only known an LPG system to work efficiently with one.

Think this is why I've got myself confused and couldn't work out how the vaporiser is heated on air cooled lpg systems.

you are confused arn't you?
The exhaust probe heats the gas before it enters the vaporiser, just a enough to stop the icing, the vaporiser is exactly the same one used for watercooled.

ok i'm back on track now. I guess i'm going to have to see what the exhaust probe looks like so i know what i'm fabricating/purchasing.

cheers for the time

With the greatest of respect .... are you totally sure you should be doing this yourself ? I know of several who've successfully done this .... BUT they were already very competant mechanics ... to be totally honest the pay-back period is so short that I'd pay someone qualified to install this for you ... I believe Gasure's number is readily available

Remember you'll also need to persuade and pay an approved installer to certify your installation and then find an insurer who'll recognise that certificate.

i'm a competent mechanic and my cousin is a mechanic who will be helping me fit the system. I;ve fitted a lpg systemwith my cousin to a watercooled audi that he owns. But trying to find any good information about fitting it to an Aircooled engine has been like finding rocking horst shi*t.

i was just unclear of the method for heating the vaporizer since there is no water to do the job and i wasn't 100% sure as to how most systems were configured.

All the best.

BTW I'm not a Gasure salesman ... I promise

BUT Steve's one of the good guys and if in doubt eh ?
