LPG numpty follow up
Jon Ison - 4/2/09 at 10:06 PM

Took the plunge, just back from Chelmsford having collected our new van.

Renault Traffic petrol/LPG.

Impressed ? You bet I am, drives superb, cost a whopping £38 to fill the 80litre tank at motorway services so I guess will be less locally, the VW transporter cost £80 to fill with diesel, over £100 not so long ago.

Change over is seamless, performance more than adequate, noise levels in cab unbelivibly quiet after years of diesels, we never carry heavy loads just bulky so not worried on that score, well chuffed.

seems alright

but, erm, petrol? (granted you can't get LPG conversions on a diesel) i hope you have a lot of garages where you can buy LPG near you. nearest one to me is 30miles away

ah, never knew that. i though LPG would need a spark, unless it uses a little diesel too just to fire?

Have you ever ran any vans on what they were designed for?

I recently bought an lpg converted car and it is far cheaper to run than my previous diesel.

Mine costs £24 to fill up at motorway services!

Unless its a woefully underpowered petrol car or a fairly rubbish diesel at the same power levels diesel still takes a lot of beating for economy.

LPG is all good for bigger engined cars though.

In my own experience of course...

BTW LPG in diesels isn't the only fuel its used to enhance power and make for a cleaner burn so you use less diesel but you still use some! (?)

Yeah there's a general myth about not being able to convert a diesel engine to LPG. It's actually only that the savings aren't that great so it would take longer to recoup the initially conversion cost.

BTW - don't forget to get a different adapter if you want to fill up on the continent !

Sorry, foreigner question: what is LPG? Something to do with ladies' golf?

Not sure but the LPG on diesels is to enhance performance bit like NOS on a petrol....... Not an alternative fuel.

Mr Whippy - 5/2/09 at 08:05 AM

You simply reduce the amount of diesel being injected and add LPG in at the same time through the intake manifold. The diesel gets the ignition of the fuel going as LPG by its own will not ignite.

Jon,
where did you find the van? I run an LPG LWB hi top tranny at the moment and desperatly need o change it as the bodywork is falling of with metal worm!

Been looking for ages but cant find anything, (except one in Blackpool but the guy was asking about 33% more then it was worth!).

conversion kits can cost around £500 if done DIY, you could buy a normal petrol one and haggle on how expensive it is to run then just convert it yourself

kit linky 2

kit linky 3

We searched for month's trying to find a transit chassis cab to have a dropside body made. We NEVER found one tho.
Since purchased a diesel as was needed and found these guys. maybe they can help. http://www.arunautogas.co.uk/ford-transit-lpg-autogas-conversion.htm

Hope the renault dont suffer with tha same issues we have had with 2 vaux combos (also hope citreon also as awaiting a new berlingo). Factory converted altho this is aftermarket by millbrook, vauxhall stock NO parts at all for these systems, one van is 2 years old and spent 4 months + off the road the other is 1 year old and spent 3 months off the road.

AFAIK there are no actual LPG conversion kits available for diesels, i.e. ones that replace diesel as the fuel.

The only ones I have seen are for LPG fumigation, which keep the engine running on diesel, but adds some LPG to the inlet air to aid combustion.

iiyama - 5/2/09 at 10:31 AM

Finding a petrol engined Tranny is just as hard!

Reckon Ive got a better chance of finding a 3.14 diff with an ATB already fitted and fully reconed for a tenner!

Ivan - 5/2/09 at 12:13 PM

I recently read that some of the local group N racers here in SA run the turbo diesels with a combined diesel/LPG mix with great success making for a significant performance increase. Don't know how true it is though.

Leaving the smelly expensive fuel and added cost of service --- Diesels are fine when still under manufacturers warranty but the problem with diesels is when they do go wrong they are at least twice as expensive to fix -- injector pumps, cracked heads, injectors, turbos are not cheap to replace.
