    Hello Funsters,

    Sorry to ask this question as it might be daft, but is it possible to have a Fiat Ducato based motorhome (130 multijet engine) converted to run on LPG instead of Diesel?

    If so, how much is the approximate cost and is there any change in performance?

    Thanks for any help on this.

    Steve

    I don't subscribe to the 'Go LPG' websites conclusions regarding mixing LPG with diesel.

    They say it's not viable, but it's been done in the US with trucks for years.

    It's also available on UK trucks with many benefits such as smoother running, better economy and improved power and torque.

    It's proven technology and can't be dismissed out of hand in the way that website suggests.

    Three years ago we did extensive tests adding LPG to a diesel engine with limited success, yes we could achieve more power as tested on the rolling road at Blackburn College of technology.

    The black smoke from the exhaust was totally unacceptable at anything above mid range revs and no matter how we did the adjustments we never achieved a penny saving on fuel.

    LPG is injected as a secondary fuel....you still need diesel, unlike a petrol/LPG conversion which runs exclusively on LPG.

    I have been running a 200 tdi disco WITH lpg for 3 years now runs and pull like a dream. But the question was can you run it ON lpg the answer is NO but with lpg YES approx. 10%.

    One of our local councils converted their diesel dustcarts on LPG but changed them back after a short while, don't know why however.:Doh:

    Occasionally drove a Foden artic for Warburtons bakery a few years ago. I don't know exactly how the system worked but the LPG kicked in automatically at some stage and then proceeded to run like a pig.Luckily it had a manual override.

    That is easy to answer, 50% extra power without any expensive bolt on bits, ie bigger turbo, different cam, ported head and so on. But..... there is always a but if you don't know what you are doing you may see the inside of the engine on the outside:Sad:

    :BigGrin: I'm not saying that I would, even if it was possible, but simply exploring the options:- LPG, Chipping or remapping. Latter two put me off because of possible long term damage to engine, etc., as well as varied opinions of expected benefits claimed by suppliers.

    At the end of the day, I'm more than happy with the performance of my van with respect to acceleration and torque, but a little bit disappointed with the overall mpg (22-24) and wanted to see if there was a cost effective way to recoup initial outlay of any modification. For example, the chipping option would pay for itself after about two years use in my case.

    Well the whole page but this bit in particular.

    Overall Conclusion

    Above it has been shown that niether true conversion of a Diesel engine nor the mixing (Dual fuelling, Fumigation) of LPG with Diesel give economic benefits large enough to make either choice worthwhile for the average motorist. With current LPG and Diesel technology as it stands, it would be more economical to simply remove the Diesel engine and fit a Petrol equivalent, which answers our original question -

    'Can Diesel engines be converted to run on LPG?'

    The answer, to date, is a qualified 'No'.

    So this system is a hybrid then? Any information as to where I might find any more details?

    I don't know if you plan to use the Channel Tunnel anytime with your m/h but as you may be aware lpg powered vehicles are banned and I assume a hybrid diesel/lpg would also fall foul of their regulations.

    We are not talking economic benefits! just good old extra grunt when you need it. like towing then you turn it off. You can not get a diesel engine to round wholly on lpg have you got this yet? you can get them to run with lpg but the reason is to get more power that is all.
