Diesel LPG Conversions

[smo]

Has anyone here with a DIESEL had an LPG converions fitted to their engine.

Normal sort fo quesitons, how much, where from, and most of all what is it like?

(I'm more interested in proper LPG systems than a propane bottle strapped in the back!)

They dont seem to do the sort of conversion i'm after - as i have a TD5 i'm after an avanced system that integrates seemlessly, its more for a cleaner burn and better economy than performance that i want it which could save me about 40-45% in overall running costs as well as potentially cheaper road tax :)

aint gonna happen

the LPG squirt does give a better fuel consumption but only because it helps with the burning of the fuel to more of an extent than just diesel,

its nothing like an LPG setup on a petrol which a fair amount of people are missinformed thinking that it is,

LPG squirt on a diesel gives a more economical burn & also reduces the black smoke output but if you have a TD5 & are after more fuel economy get it chipped & drive like a normal person

LPG on Diesel can give better economy - more power/efficiency should mean that you can stay in a higher gear for longer etc.

You won't - you'll just go faster.

But 40% cheaper? Nah......buy a micra!

Oh yes it is, i know of several big companies that offer it, with evidence to back up their claims.

I just wondered if anyone around here had done it.

I also know that chipping doesnt increase economy in reality - and thats from experience with my last TD5 :D

I wont go faster, the car does over 90...i know i've done it but even on motorways i drive it at 55-60 because thats where its most efficient and quietest due to the gearing.

Yes 40% cheaper, (work out a 30% reduction in consumption coupled with fuel thats about 60% cheaper)

As for the Micra - go wash your mouth out!  :P

[waveydavey]

Keep us informed if you do it; I've looked at it a couple of times and am very interested.

aaah, i think you mean the conversions that convert a big diesel engine into what basically amounts to a petrol engine
they drill and tap the heads to take spark plugs and somehow fit a dizzy, and run it purely on LPG, with the possibility of switching back to diesel

its apparently not possible on a smaller engine, due to the lack of space
this is all info i've picked up from a drunken conversation in a pub, so it could be miles from the truth......

No, no conversion into a "petrol" - merely a system which is (ECU) controlled and mixes LPG with diesel to produce a 100% (or near enough) burn of the fuel, lowering emissions and increasing economy.

There are 2 methods, on is squirt in as much "gas" (lpg, propane, LNG) as possible and you get more power, or do it more scientifically and itll mix the right quantity for the throttle position etc and you get much much more economy and also a bit more power.

ok
tinleytech do kits to convert diesels to LPG:

Yes 40% cheaper, (work out a 30% reduction in consumption coupled with fuel thats about 60% cheaper)

But you're buying the LPG on top of the diesel that you would have got anyway.
I've had a look around and they claiming anywhere between 15% & 35% saving on the fuel. But as you're using about 75% diesel to 25% LPG, and with the cost of the conversion being the same as a full LPG kit on a petrol, then it will take a long time before you start showing any significant savings.

They seem to be agreed that it adds power and reduces emmisions but if the main reason for the conversion is to reduce the running costs then, with the current systems available, it looks like you need to keep the vehicle for more than 5 years or do very high mileage to see any real difference.

LPG is less than half the price of diesel, soon to be 1/3 the price! So using this instead is instant saving, facor in the increased mpg (approx 10-15mpg when done properly) and its a big saving, also reduced road tax due to reduced emissions- could well be worth it even after a few months.

I do a lot of miles, and have no intention of getting rid of my baby unless i become rich and buy a D3 or RR sport.

Ian

The only prob i see with this is that the compression on a diesel is a hell of a lot higher than a petrol

Also, with costs on conversions, the only ones which will really make it worth while are fleet vehicles running 24/7 on lpg/derv

still the main options that would suite general use would either be petrol/lpg engine or bio diesel

[smo]

Bio diesel is more expensive than normal diesel, and rare in the UK. If you mean SVO (veggie oil) then you meet a massive tax bill and all sorts of certification problems, quality issues and other oil related problems which negate the benefits before you start most of the time.

or go electric  :lol:

[tomarse]

Is this a cross post from A.F.L? (theres a similar thread there too!)

Hi Smo, have you tried speaking to car-gas who are in fenton/longton (http://www.car-gas.co.uk/). Fairly local for you too.
I believe they did one and there was an article in one of the landy mags about it.

They know their stuff and their landies too (They own a few between them)

[smo]

Whats A.F.L??

[mark.yellow.series.3]

remove the floor pan and pedal it flintstone stylee :lol:

[Doobreydog]

Have done plenty of research into this in past and will try to find the links etc to back up what Im saying...Have run a van for a number of years on home made bio-diesel and apart from the tax :lol: cost me nothing...at one time the company I worked for actually paid me to dispose of their old fryer oil :D

Unless you do massive milage 25k+ per year even in LR then the cost of the diesel to lpg conversion is prohibitive.

If you already have diesel and want to keep the low down torque either bio-diesel or home made biodiesel (you still have to pay the tax  :roll: ) and after tax does not work out any cheaper. Most diesel engines will perform well with non or very little conversion.

Cheapest way to go is converting petrol to lpg and get it done professionally it will pay off in the long run.

Currently getting 200miles for under £20 which in money terms is equivalent to 45+mpg and I dont go slow.

Hope this helps...

Firstly the TD5 wont run on biodiesel of more than 5% and certainly wont run on SVO/WVO (so LR say and i aint trying it as i dont know of anyone who has)

As i do 18K a year, and plan on keepig the vehicle for many years the conversion cost of £1500 is recouped in the first year, and then i make  anice saving every year after that.

[LOFTY]

My 130 DC i use for towing, has a powershot system i bought from the States, its fully adjustable, and you notice the differance. Towing up hills where i would normally drop to say 3rd gear, will cruise in forth, it makes it smoother to drive, well if a Land cruiser engine could get any smoother.

But the LC engine has a mechanical pump, so after intercooling and pump tweeking, theres n o easy way of getting more power, so i fitted the Powershot system, only took a few hours, and fully switchable from the cab.

dont put Vo or bio fuel in a td5 as the pumps die very quickly
