Thread: D-gas versus Dieselgas

I found it highly unlikely that the government would pay us to fit something illegal. After 5 seconds of research I came up with this


See below.

"The emission standards were introduced via two new series of ADRs, which apply to vehicles depending on their gross vehicle mass (GVM):

* ADR79/00, ADR79/01, and ADR79/02 for light-duty vehicles at or below 3.5 t GVM (replacing ADR37/01)
* ADR80/00, ADR80/01, ADR80/02, and ADR80/03 for heavy-duty vehicles above 3.5 t GVM (replacing ADR70/00)

The new ADRs apply to new vehicles fueled with petrol, diesel, as well as with LPG or natural gas, with an implementation schedule from 2002/3 to 2010/11. The requirements are summarized in Table 1 (the requirements and dates for heavy LPG and NG vehicles are the same as for diesel).

The two year date combinations shown in the table refer to the dates applicable to new model vehicles and all model vehicles, respectively. For example, in the case of 02/03, this means that from 1 January 2002 any new model first produced with a date of manufacture after 1 January 2002 must comply with the ADR, and from 1 January 2003 all new vehicles (regardless of the first production date for that particular model) must comply."



SO it only applied from 2003 vehicles onwards.

Yes, that extract applies to new vehicles.

Anything there about offering a commercial conversion that will alter emissions?
It does'nt surprise me that one Gov't dept has no idea what another does.

Just to put the situation in perspective -

1. Most states now have legislation to prevent insurers from evading payment of claims where the insured's transgression has nothing to do with the claim - and unless the claim is related to the modification (e.g. gas leak resulted in fire), and even then they would have nothing to stand on if they had been notified of the fitting. Although they might try to recover from the fitter's insurer. It is difficult to see how a failure to comply with emissions standards could result in a claim, and most gas system suppliers claim improved emissions results anyway.

2. The number of gas fumigation vehicles which may be technically non-compliant would be miniscule compared to the number that have had the fuelling modified without the new chip being submitted for compliance testing. And in most of these cases emissions would have been increased - but any insurance implications would certainly not come from the fact that the new fuelling scheme has not been submitted for compliance testing.

Certainly in most if not all states and territories the days of insurers rejecting claims for irrelevant reasons are long gone - occasionally they will try it, but it is pure bluff.

Just a quick heads up,My defender has been driven hard,I'm trying to get it to knock or have a drama but it hasn't even looked like having a problem with a 40thou gas jet,anyway I has returned after 1600k's 135ltrs of diesel and 40 ltrs gas in a mix of town,open road driving.That amount includes playing with the set-up and test driving etc and me giving it a hard time.The engine pulls stronger from any gear,very noticeable in third and fourth,in fourth it is limited by the gearing and I past a three trailer road train on friday in fifth from 80 up to 120 and it pulled past no drama's.It is early days and a tune is happening in a week or two but I'm likeing the gas more and more.I'll post up the dyno sheet and give it a few more tanks and post up the results. Pat

You would have to be happy with return 8.4 litres per 100k, although the LPG @29% is a bit on the high side according to the installer I used.

It's early days.It has spent a fair time at idle which would help the diesel side but it will get a tune on both shortly. Pat

Hi Pat,

Have you had the dyno bit done yet? Very interested to learn of your results.

Cheers,

Paul

Mate done already.See my thread Dyno results D/gas. Pat
