Thread: Isuzu emissions standards?

The Tdi has a label on the side of the engine saying that it complies with ADR 30/00 which first came in on the 1/7/76
http://www.google.com.au/url'sa=t&rc...tTIbew&cad=rja

So that would easily include the 4BD1T

Also;

• The first emission standards (apart from smoke standards) for heavy diesel fueled vehicles became effective in 1995 for all new models and in 1996 for all existing models. These emission standards were introduced via ADR70/00 (adopting ECE R49, US & Japanese HDV standards). The requirements of the 1995/96 standards were:
  
  • Required: Euro 1 for both light-duty and heavy-duty vehicles. Euro 2 and 3 were also accepted though not included in the regulation.
  • Acceptable alternatives: US EPA ’91 or ’94 (EPA ’98 was also accepted though not included in the regulation); 1993 Japanese exhaust emission standards for “light duty and medium duty vehicles” and 1994 Japanese exhaust emission standards for “passenger cars and heavy duty vehicles”.

Emission Standards: Australia: On-Road Vehicles and Engines


I think the 4BD1T is Euro II ??


According to this current doc, the industrial version is 'Tier 2'

The problem Rick is the Euro emissions standards for light vehicles are based on g/km whereas heavy vehicles are g/kWh. I am not sure which the 130 comes under???

If the engine was the same year or newer as the original engine, then I don't think transport would look too closely, however the last 4BD1Ts were mid 90's. Basically when Euro1 came in for HV's in Australia.

I think that's where companies such as KLR state they can't fit the 4BD1 to a post '95 Defender, even though the engine may well meet ADR70 (which was active from Jan. '96)

Interestingly, under ADR70 these OS standards are acceptable;


6.2 Alternative Standards (Clause 6).

6.2.1 The USA Code of Federal Regulations, Part
86, Sub-parts A and B - "Control of Air Pollution
from New Motor Vehicles and New Motor Vehicle
Engines: Certification and Test Procedures" for 1991

and "diesel heavy duty engines and vehicles", or for
1994 model year diesel heavy duty engines and
vehicles"

6.2.2 The Council of the European Communities,
Council Directive 911542/EEC of 1 October 1991,
amending 'Directive 88177/EEC on the approximation
of the laws of the Member States relating to measures
to be taken against the emissions of gaseous and
particulate pollutants from diesel engines for use in
vehicles", as per the limit values in line A of the tables
in section 6.2.1 and 8.3. 1.1 of Annex I to the
Directive.

In January 2002 ADR 70/00 is superseded by ADR 79 for cars =< 3500kg GVM and ADR 80 for cars > 3500kg GVM (all Defenders fall under ADR 79 from 2002)

you have to meet the emission standards for the year of the chassis that your transplanting the engine into. (euro I for a 1997 landrover diesel anything)

in stock form the 4bd1 is euro 1 compliant and can be tweaked to meet euro II Euro III or better needs aftercare treatment for the exhaust to the tune of a 3 way cat and DPF including ADblue or equivelent if you need to crack euro 4+ reliably.

Euro 5 is achievable in theory but I wouldnt want to try it.

Any proof of that Dave???

And despite your earlier assertions that emissions compliance testing is cheap, ring these guys for a quote and see what they say:
Emissions and Driveability | Testing & Calibration

Thanks for the responses guys.

Dave, it was a post of yours in another thread which prompted me to consider the 4BD1. Is there a compliance plate fixed/ stamped to the 4BD1 or document ( suitable for proof of standard)? This would make the legalities of the swap a doddle to prove to the relevant body.
I have no desire in attempting to prove emissions through testing. It is too hard, expensive from Alice.

Info from the Chinese knock offs suggest Euro 2. Yet I think I may have to acquire specifically one of those engines for the documentation to be accepted by the relevant body.

Further now I note I have stuffed up with the year model. I actually have build date of 10/95 and compliance date of 4/96. Compliance plate states built to standards of 1989. Sorry was looking at rego papers for the info in the first post.
So in theory if a 4BD1 from a vehicle built to standards from 1989 should be ok?

Rick my TDi has no plates on it maybe covered by muck.

Can someone advise the standards on the compliance plate from an Isuzu County?

Cheers

You could always have a look at these docuents between Isuzu Japan and Jaguar Rover Australia then later with British Aerospace, the remanufacturer contact for the perentie rebuild line.

Isuzu 4BD1 complete engine

Last time I had to do an emissions testing it was $50. turn up, start engine, drive onto rolling road then they stick the sniffer in the exhaust the partical trap on the end and away you go with your emissions cert for the vehicle. There was a call out rig sat there at the roadworthy place for about a week. from memory it also provided the required test details for the brake and handbrake performance (fun to watch on a series when it was raining one wheel would skip backwards the other would roll forwards and you would fail your handbrake test)

fortunately till you hit euro III the emissions is basically taken care of by direct injection ,good injectors and fuel EURO III is when you need to start playing with electronics to hit the standards required but you can still cheat your way there by after care with a good 3 way cat and DPF.

EURO 4 complaince means you're going to need the ADblue type stuff on the exhaust.

The engine should come with a plate on it advising what standard its been setup for sometimes its attached to the pump others to the rocker cover
on this one the plate would be attached to the raised part on the rocker cover or stamped on directly. I doubt you'll find this info on a pre 90 version of the engine.

you'll often find that it will quote a jap standard for its setup, just find out what that spec means and bring a print out with you come compliancing time.
