LPG conversions for Diesel vans?

3sheds

Guest
Hi,

I'm 3sheds and have just rejoined after letting my membership lapse for a few years.
I'm on gardening leave and will be retired by the end of July and am investigating an LPG conversion for my selfbuild Transit 330 both to increase mpg and also to run my cooking and heating off.

My van (late 2002) has a 2.4 125 ps intercooler turbo and what I'm after is increased mpg as even driving at 55 all day I can't get 30 mpg.

Has anyone out tried this on a diesel and if so I'd like to hear any in's and outs.

Cheers

Eric
 
Have you tried google or the search facility on this site. Discussed. A while ago.

Sorry cant help with personal experience.

Comments I've read about the autogas / diesel vary from fantastic to its a total rip off. I have a feeling that the newer diesel engines dont do so well with all the electronic sensors for oxygen, exhaust gas temp, etc. etc. I read of one very disgruntled Toyota Coaster owner who had blown up two engines with overheating.

There are some safety concerns with using the fuel tank as a supply to appliances. In theory as soon as the engine is turned off the fuel supply should be closed at the tank - which can prevent the use as appliance fuel!! I think the issue about closing the gas flow is to ensure that you dont get gas leaking into the manifold and potentially doing some serious damage when the engine is restarted. With duplicate solenoid valves it should not be difficult to overcome closing the gas supply to the engine - whether that complies with LPG/vehicle regs is another matter.
 
if you were to use the same tank you take vapor for cooking at the top and use a totally different take off from the bottom of tank for liquid . but why run lpg on a diesel .we have some council run trucks down here but i dont think its a viable thing really .also plymouth used to have lpg powered buses but dont hear much about them now. think converting diesel died a death.

Oops I was thinking it was keeping the diesel and adding propane to provide additional octane - more power/less consumption? rather than a complete LPG run diesel engine which I dont think is successful.

Many urban bus fleets run their diesel fleets on compressed natural gas which seems to work ok.
 
Before you go too far down the LPG conversion road you need to look at how many miles/kilometres you plan to do per year. You then need to work out the price of what ever fuel your vehicle uses. The the depreciation on the vehicle; remember, they don't last for ever. Do the maths, it can be alarming

These conversions are not cheap and although they look good value, the only people that I have known of for whom it is economically viable for are the commercial users
 
cng is very common in japan .i,v seen some lovelly buses built by nissan . the civillian bus makes a great camper. trouble is they dont run on petrol any more only gas . they do swap to lpg and there is a firm up in scotland importing them in small numbers .try googling sales@dj4x4direct.com if you are interested. but for most of us fill your gas bottles at the pump . use diesel it works at no great expense. cheers alan

Hi
have hacked about this subject some, does your van have a ems if so you would be better off getting it remapped rather than going for gas. bty diesel is only 112p mostly in europe.
