exhaust EMISSION Oz and Nippon rules

[steptoe]

I had an interesting chat with a guy financing equipment requiring ADR emission approval.

He was attempting to get his own LPG equipment designs approved. Approval requires the vehicles to be used as test subjects have less than 23,000 km on the clock.

What he allegedly discovers is the reason that all these Japanese import cars and engines we been getting for decades now, that no longer pass Japans tough emission laws that apparently continue to get stricter every few years - we all seem to acknowledge this as the reason given so we have no hesitation in buying either the cars or engines.

The gist of the allegations is that it is no different with cars on our roads - their emissions control systems do not retain the same standard of control through the life of the car likely to degradation of many components involved. Two such things I have encountered is the EGR bleed off solenoids get stuck or as the manual refers sticked to open or sticked to close - either way no longer working as designed. Another is the cat converter suffering some different ways of self destruct.

What an engineer faces to get approval on LPG is that the LPG system (or any new fuel application other than the car was approved with)must meet the criteria on these test cars is that due to failure or improper function of the engines emission controls for petrol will also impact on the LPG side therefore may not meet the standards.

While allegedly finding that a cars petrol emissions control may no longer comply working on petrol the governing bodies may not be required to care by law, they are required to care of the LPG sytems emissions to a very tough standard.

What the conversation seemed to suggest was that it is regarded that cars on petrol over 23000km may no longer satisfy emission requirments here in Oz and nobody has to check to see if they comply with the exception for when an engine or car is modified and then subjected to emissions test, then the trying times start.

I am wondering just how many of cars on our roads would pass the emissions testing required on their release or ADR approval date

long winded but I guess you will understand.....

What the EPA doesn't go to any length to tell you is that they can't easily test early emissions ADR compliance .

Also a rego inspection (in NSW anyway) is no longer a compliance inspection , it's now just a basic safety inspection .

The EPA can be really nasty and insist on emissions inspections on later vehicles , innocent victims can be dobbed in and the car has to be tested .

Cars with full engine management systems - the self learing variety - keep pretty close to legal and their OBD systems throw codes/dash lights if they can't .

We have been lucky so far that smog tests are not manditory at the yearly inspection , in the US if you fail smog you don't get registered till it's fixed .
Here it's legal because the compliance plate says it is .

Lastly it's pretty pointless going for type approval with a worn engine , if the rings and valves don't seal properly it'll fail for sure . The test engine needs to be fresh and to OEM standards - meaning round parallel bores and good rings/valve seats/valve stems/guides .
