What system is it

[garryseries3]

Hi all
Yes I know what it says on the box, bought this second hand unit off Ebay a few weeks ago for my isuzu 120. I would like to clarify which unit it is as would like to know is it able to be registered in Victoria legally and who to get to fit it off in Victoria. I believe I can get the rebate which is now a $1000, is this correct and is it a good unit if it works which I am assurred it does? Here is an image[IMG][/IMG]

Also there a couple of bits in the loom that I ponder what is it they do.
[IMG][/IMG]I would think this is the gas feed into the inlet, is it a fumigate type or direct and does it matter?
[IMG][/IMG] Whats this bit do with the three lobes?

Also these ones, what are their purposes?
[IMG][/IMG]The shiny probe I am sure is for EGT the plug in the image has written on it not used.

This lgp unit came from a 300tTdi Disco but my isuzu is not turboed (Yet) so do I have an issue using it till then? Also does anyone have images of there underbonnet setups for these units in Defenders.

regards
Garry

Nice score - from reading the website, it's a self contained electronic gas fumigation system with a variety of sensors that stand alone. Unlike older diesel + gas systems that rely on turbo pressure to switch on ( google bully dog propane ), this one apparently has a stepper motor to adjust the gas flow, like what you find on LPG systems that piggyback onto EFI. So,after installing the various sensors (MAF MAP etc .. just like EFI) and a laptop to program it with, you should be good to go. Otherwise it's just another gas installation and all that goes with it.

Well that is a relief if it is the one that read the sensors and inject the right amount of gas. Is the stepper motot the three lobed bit?

It's a Diesel Gas Technologies Sequent II LPG Fumigation system. It is a microprocessor controlled system.

See this from the New Inventors New Inventors: GasTek

The probe is an EGT probe.

DGT are here in western Sydney (02) 4732-3700 (oe 4721-3675 - may answer as KLR Automotive), or from Modern Motors, Dungog, NSW, both are LR specialsts

Hi Thanks foer that Ron but it seem that after talking to Matt they longer have anyone outside of Penrith and Newcastle doing their fit off as there has been some major issues with quality control and fitters taking the money and not caring. So I need to find a fitter that will fit it off down here. Seeing it took over 12 months to get up to Sydney recently I not going back real soon. So if anyone knows someone that will fill it of I can proberly send the ECU off to Matt to be set up for my landy.

I forgot to say what the bits were.

First pic is the converter and microprocessor.

The second pic is the injector. Not sure about the third pic. The 4th pic is a pressure sensor (manifold vacuum/gas pressure I assume if it like the one in my petrol V8 install).

Last pic is the EGT sensor probe. I think you'll need to drill and tap a hole in the exhaust manifold for the probe.

I used to assemble and package the kits for DGT at one stage.

If I see a set up, do you want me to take pics. Finding one in a Isuzu LR might be harder.

You might find that DGT have the laser-cut stainless steel brackets required for installation of the injector. Brackets were vehicle specific. Ditto for the gas tank brackets for chassis mounting of the tank. Do you have those?

I'm going there today. Do you want me to ask?

Hi Ron
Thankyou for clarifing the components, we have spoken in the pass about this set up when I initally was considering what unit to go with for my vehicle. It is good to know that I got this system, as then and as now it seems the best on the market. Pity about DGT only being NSW, the Vic fitter was a reason I did not move forward and have it done here in VIctoria, it seems my perception about the quality of the work were proberly correct. I fully understand Matt and the guys reasons for limiting the authorised fitters of their systems, just a pity as it is limiting.
That said Matt seemed very considerate in helping us out once fitted up. My understanding is that the boys at DGT have isuzu landys with this system fitted up on their vehicles, I am not sure if they are in Defenders or Discoveries but photos of where they placed components in the engine bay would be great. I am reasonably good at doing modifications so will considerer fitting the loom, ECU and the other components and getting a LPG fitter to complete the task. I have been recomended to a LPG fitter by a mechanic friend that is very good with one off modifications so I hope he is willing to do it. I have already fitted a 75L scuba tank under the tray but will leave the plumbing up to the LPG fitter.IMG][/IMG]

A laser-cut stainless steel brackets required for installation of the injector sound like a good piece to have who ever has a isuzu Landy at DGT may have adapted another one to suit or have one specifically for an isuzu. It would be good to know where to fit the adaptor or what it looks like so as to have one fabricated and how critial its place in the induction system is.
I have a 3" exhaust system that came with the the LGP system. Matt said that seeing that I do not have a turbo fitted that it will require a drive to Penrith or possibly Aulbury to set the ECU parameters for the motor(a 10 min job). If it was turboed he could set the ECU up if I mailed it up to him as he has preprogramed specification for it. For now I think I will get the system fitted off and deal with that issue when I get to it.

I had lunch with Matt yesterday and he mentioned the Albury option — Brad was there this week. Both Matt and Brad have 4BD1-T powered Rangie classics.

I'm not sure what bracketry is required but I'll ask next week when I go there to get my car inspected for rego. All the imjector and converter mounting bracketry was designed by Brad and laser cut to suit particular cars. Very little none of it was generic. Most of the tank mounting hardware is generic but still made to Brad's designs.

I'm pretty sure you need a threaded bush for the EGT. The manifold is tapped for the bush and the EGT nut screwed on. It's been quite a while since I was making up kits for shipping.

Thankyou Ron for inquiring yesterday and if you ask about the bracketry for my 120" ute that would be great to find out.




The engine bay is fairly tidy and clean as in this image.



I have replaced the bonnet and doors while getting them resprayed Shire Blue its original colour.

My interest in the gas system is more about running a more efficient cleaner engine as I am a environmental professional and it seemed a tad hypocritical driving the isuzu 120. The turbo is another can of worms at this point and to be honest the amount of torque the motor has compared to the 130 Tdi I had is almost ample for my needs, in fact since I have had it I have incured several speeding fines. After 12 years in the Tdi I have just not gotten used to my new Landy breaking the speed limit. I have a VNT turbo to put on and there is a thread here that deals with fitting this to an isuzu but there are some modifications required to deal with the boost compensator that I have not the time to deal with. But I think first I would like to guage the increase in power without a turbo and if it meets my needs then I will leave it alone or take the next step to turbo the motor.

I fitted off twin tanks and a full gas carby system to my HQ one tonner years ago so have some familarity with requirements for LPG. I am confident the tank setup is legal the way it is secured to the chassis.
