Dose anyone here with an Isuzu powered landy have the diesel gas hooked up? How much did it cost? And it it worth it?

Just for ****s and giggles I ran some lpg into the intake of my Isuzu while it was cold and idling.

I've heard many reports that the LPG quietens engines down at idle. Yes it did, but only because it raised the idle speed by 50rpm or so. A light touch on the throttle linkage makes it run exactly the same.

But the interesting part. If I ran just a little more lpg in then the engine started labouring heavily. It was detonating which was advancing the timing to the point where it ran rough.
This on a cold diesel running at idle with no boost.

I think you'd need a hole in your head (an extra hole most people don't have) to run diesel gas on any diesel.
More power, sure. But what's the cost?

not meanig to be rude, but i imagine the guys that produce the diesal gas systems would do more than just stick a gas hose into the inlet. my guess is there would be some tuning required. As in any modification whether it is diesel or petrol, n/a or turboed any mods like this without tuning afterwards could be disasterous. only thing is i don't know what amount of tuning there is available on the isuzu's, so i'll leave my comments a that.

with the recent bout of infighting i was loath to post, but decided to after all, like i said, not intending to be rude

The fact is, LPG detonates in a diesel engine. This is caused by the high compression ratio of a diesel engine and cannot be altered by tuning of any description.
The only tuning that can stop that is to stop using LPG.

The BS meter is currently off the scale with some of the marketing claims being made about this. A little experimentation can show the problems clearly.
A little research will show the downsides outweigh the upsides, which is why no diesel engine maker condones the practise.

Yea guys...........constructive comments please.

I'm hearing what your saying about the detionation and such, but it's a little more complex than that, otherwise I'd rig it up myself.

I'm after actual accounts of people that have had it installed, I suppose it dosn't even have to be an Isuzu power pack, it would just be more relevent thats all.

Hey mate, I've decided to get it however it is for a tdi Engine. I recently saw someone with a tdi disco which had it on so I chased them down to ask how it was going etc... and this guy was very pleased with extra power. He said He probably gets a bit of fuel savings but he felt it was more about smoothness and drive-ability which were both improved. He had it for about 35,000 kms so far and said he'd probably stay with the tdi engine when this oen goes because with the gas it was ice to drive.

There was a bloke at the pentith LR show last year running his isuzu on LPG (no turbo), and he loved it (he had OUTBACK LINK written across the front). He said it was smoother and had more power.

What were you driving when you chased him down?

Just for performance comparison.

Cheers
Simon

there is a $2000 government rebate for the gas system. all up it would cost about $1500 once you have got the rebate! it is worth every cent of it though especially with the new system dieselgas technologies has! and there is alot more required then shoving a hose down your tank! if you have any questions about the gas feel free to ask me!

You have LPG on a 4BD1?

You have LPG on a diesel?

What setup?

What sort of power increase and economy increase?
