diesel lpg conversions

[dobbo]

Hi the other day whilst at the 4x4 show I saw a company advertising LPG conversions on Diesels costs ranging from 3 - 6 thousand dollars. According to the salesman there is a vast improvement in fuel economy and up to 30% increase in torque. He had three vehicles on display a Defender TDi, A patrol 4.2 and a current model f150 v8 diesel. Now these vehicles have one thing in common all of their engines are fairly basic low tech mechanical diesels. It may have been just a coinsidence but the first thing I thought of was what is wrong with this fuel running in a high tech electronically controlled diesel engine such as a TD5, TD6 ,TDv6 or a mitsubishi DID. I know busses have been running these set ups for years but have not heard much about them of recent years. Does anyone know how they are still going, any drawbacks , advantages , experiences perhaps.

Make a search in the forums (or the old ones www.our4wd.com) for "dieselgas"... plenty of information to be found from those...

They were happy to do the TD5's. Only reason I havn't done it yet is the $$$.

Hi Dobbo
They only inject a small amount of LPG into the intake manifold.
It works so well as the LPG acts as a catylst that enables the diesel engine to burn 100% of the diesel injected.
Most diesels can only burn 75% to 85% of the fuel injected depending on atmospheric conditions.
The computer wouldnt even know the LPG is there and would go about its job as per usual.
The main problem is if you abuse all that new found power you are pushing the motor/drivetrain well beyond its design parameters and something will break.
A TD5 with a chip/larger intercooler/ chip upgrade and LPG fumigation,a flyer no doubt.But also a hand grenade if you thrash it too much,how much is the million dollar question????

I think the worst thing you would get with a TD5, is sending the auto box into 'limp home' mode if it thinks it's getting too much torque. If your manual, no problem. When it comes to fitting it to a vehicle like a Pajero DiD, the question is 'what the hell are you doing in one of those anyway?'

LPG to a diesel is like NOS to a petrol engine. to much and kabang.

lpg injected diesels have been around since world war 2 where they were used because of the shortage of fuel. the technolagy died off in the fifties before making a minor come back in the early eighties. lpg and nos injection is completly different nos is a sudden shot of gas into a petrol engine to make it go faster and lpg/diesel is a constantly measured supply of gas and fuel into an engine to make the fuel burn more efficently hence you get better fuel economy. and if you want to see a diesel engine go bang wash your finer filter in petrol and it will blow the head through your bonnet, i've seen it happen on a rodeo.
