Thread: Diesel Gas Canberra

I spoke with the Sequent II guys - they're in Orange NSW from memory & they didnt know of anyone coming onboard to do installs in Brisbane. I am keen to hear feedback from those of you who get it done in the future. I would consider it for the power boost.

Yesterday I was chatting with a chap here who does duramax conversions into 4WDs. A 6.5ltr supercharged chevy into a patrol / disco = $35000 & then they go & get a gas conversion!!?? Who'd figure they were worried about economy. Ha. Makes me laugh.

Ok, there are a couple of differences between Diesel Gas vs ULP.

With ULP at 5% to 10% it speeds up the burn and gives a more complete burn but it also thins the diesel so you tend to change the spray pattern and can possibly lean out the mixture and burn the tips of your injectors espesially on direct injection diesels.

With LPG fumigation, it does a similar thing in increasing the speed of combustion thus increasing the amount of fuel burned in the process but without damaging the injectors, injector pump or the engine from predetonation.

It doesnt do much harm to run 5% PULP a couple of times a year to clean everything up a bit but a good fuel treatment is better.

As I posted in the other LPG/Diesel thread, I have been told by 3 well respected LR specialists that LPG fumigation can blow head gaskets but I am of the thinking that they would have been dealing with it in its early stages and things are probably much better now.

Gerry - let me know how you go with adding ULP to your fuel tank... You might wanna film it for posterity!

Adam, I'm not saying I actually do it!, I'm just airing my concerns about these DieselGas systems, for example:


What would be the difference between adding gas and adding ULP; cost aside?.

How does the Gas produce lower EGT's as claimed, and still give more power?.

Another point is storage of the Gas, is it allowable to have tanks inside the vehicle?.

Also, filling LPG tanks has always been a PITA, especially when they are small and separate, or has this changed?.

I bet no one is touching the warranty issue!........to be expected.......


Like I said, if it is as good as these guys claim, all diesel transport machinery should be fitted immediately without delay, we have heaps of cheap LPG in this country, it should be utilised!.

This technology is not new, I wonder why major transport companies haven't taken it up?, with all the benefits you'd think the waiting list would be years!.

Imagine the savings that could be made on diesel locomotives, trucks, buses, let alone the reduction in greenhouse gases, are councils, trucking firms, etc fitting this system to their vehicles?, if not, why not, the subsidy is for everyone.......I urge caution, but have an open mind........

I touched on a couple of issues with using ULP with diesel in my previous post and there are some really good tech articals about it on here somewhere so if your interested do a search.

As far as why dont commertial opperators use it, there are a couple of bus companies in Melb using it and quite happy but the warrenty issue is a major reason why more commertial operators wouldnt be using it.

As far as LPG tanks in a vehical goes, no problem having the tank in the interior, it just has to be a. fitted by a qualified/certified LPG fitter and b. Has to be securely bolted to the floor of the vehical c. vented to the outside of the vehical.

They have been fitting LPG tanks in the cabins of cars since the early 80's and it's not much different now.

As far as filling goes, they now have whats called an AFL valve fitted to all gas systems since 1986 which will only allow to fill to 80% with no bleeding of the system nessesary.

I think that pretty much covers it.

edit : just to add, there are also a couple of trucking companies and bus companies down here that are trying out natural gas systems as well, I know of 1bus company over near ringwood and 1 in Geelong as well as a trucking company out of Keilor aswell.

Ah yeah, fair one Gerry. I know some say you can put a splash of ULP in to clean things up - I would rather get it done properly in my D2 though, just too much money to be spent if it stuffs up.

I would think that a decent chip would give a similar result with a lot less risk (and cost). I know that gas has been used in the US for years in buses and trucks - different to a car though.

Not sure what systems he will be using..

Give them a call on 02 6241 8777 and see what he intends doing..

I've just sold my TD5 Disco..but was considering getting it done..

cheers,

The Canberra Motor Works is the last organisation I would let near my car based on my past experience. Plus take twice as much money with you as you will think you need - they know how to empty your wallet.

IMHO as soon as someone mentions 'rebate' all the best things happen. Like the price doubles, claims are made that Power jumps 50% mileage is phenominal etc etc etc.

Look at rainwater tanks here is Brisbane. Before the plumbing rules changes they were selling 100s a day at $1500 for a 3000ltr tank. Now a couple a day & you can get a 5000ltr tank for 900 & a 10000ltr tank for 1500.

The govt would be better of rebating flash tunes & asking for emmisions tests every 2 yrs for those that took up the rebate. That would get fuel burning better & reduce exhaust gases.

Maybe they could start with there various belching bus fleets nationally.

As is said above IMHO.
