Right then.

Because of the -40c or so you get from liquid to gas phase change when it is released from the tank, the evaporator is warmed by the cars coolant. If the coolant isn't warm enough you get the evaporator icing up solid. and potentially, depending on the mixture, freezing the coolant too (not very likely I know). The frozen evaporator can bugger up the internal workings and seals.

I'm not having a go at you

I'm not sure it's as big a problem as it's made out to be then, because it certainly never presented any problems on the pick-ups. Maybe they had some sort of heating device built in to them, but they were certainly LPG-only.

I'm guessing some kind of electric preheat of somekind. Anyone know how LPG only fork trucks work?

i'll go for bumble bee from transformers in new shape chevvy camaro form thanks :)

Almost certainly.

Could you not inject the gas in still liquid form a la nitrous systems? That'd avoid evaporator problems entirely.

Always bearing in mind that the amount of heat required is a direct product of the amount of gas required. I know that's obvious, but sometimes people forget that.

So, my little Golf at 30mpg on Gas gives the vapouriser an easier life than a V8 at 9mpg. With lashings of antifreeze, I reckon I'm safe to run on gas

Ultimate demo of the principle of gas turning to liquid and the heat absorbed in doing so.

That'll be liquid phase injection which I am advised the more modern Pauxhalls do.

I love the Kiwi beer cooler.

They do, but apparently it doesn't work to well. I think that is why a lot of people who tried LPG will have tried it through a fleet vehicle with it working badly. Hence some of the daft opinions presented by the troll types.

Having said that, once "warm" pretty much any sequential system, and some single point systems will start on gas for the rest of the day. It tends to be first start that needs sorting.

The guy I bought a few of my 360 bits from is an LPG engineer and has a well sorted 340 that runs on LPG only. If you're really interested I can ask him a few questions.

Would definatley be interesting to know. I would have another LPG car again, when running properly on it, the rangie ran better, and more economically on gas than on petrol, and that was a piece of shagged out nastyness with the ultimate pikie cobbled together messiness jokingly described as an install.

Superb :-)

Liberty GT wagon. And I think I'll be getting one in about 6 months.

You are right. I'm changing my mind to a Veyron.
