Failed emissions inspection!
|
Gary McEachern
Hello SubaVolks
I took my van to be inspected today and failed the mass enhanced emissions test! Boy was I surprised because the suby engine runs and smells so much nicer than the VW engine. The test was run as if the engine was the VW waterboxer. The emissions are read with the van driven at speed on a dynamometer. HC was 2.37 with a limit of 8.25 CO was 51.38 with a limit of 94.36 CO2 was 753.49 NOx was 10.45 with a limit of 9.27! I'm running the original VW exhaust components (cat and muffler). I suspect the Cat is bad. I haven't hooked up the test light to read out the ECU error codes yet. I plan to do this later today or tomorrow. Can anyone tell me what typical readings should be for this engine using the VW exhaust? Any suggestions will be greatly appreciated.

Don't *know* but here's my observations...
Gary McEachern wrote: "The test was run as if the engine was the VW waterboxer." It ain't. AFAIK the Test should have been run for the engine that you have. HC was 2.37 with a limit of 8.25High NOx usually indicates an lean mixture. (Burning too hot.) You might return to the smog station and ask for the specs for the engine that's in your rig. If your readings are w/i the range of the specs, have it retested. Else??? Jim |

It appears you are running a bit to the lean side. You might try a new O2 sensor if you already haven't replaced it. The cat doesn't remove nox. Maybe you have one cylinder running lean. Check the plugs, they may show the lean cylinder. Try some gasohol if you have any over your way, or some injector cleaner that will clean out the injector system.

Check for over-advanced ignition timing and/or a lean condition.

Thanks for the information. How could the ignition timing on a suby EJ22 engine become over advanced? Since there is no distributor isn't the timing electronically controlled with no provision for adjustment? Gary ----Original Message Follows---- From: "Justin B.

Good point! Anyone out there know what "normal" emissions readings are for the Suby 2.2L engine? Is 10.45% high or could it be normal for this engine.

The cat can also have a big impact on nox. I have been looking over the bosch fuel injection book and the subaru shop manual. They both point out a good mixture and 3 way cat help to reduce nox as well as hc and co. I somehow thought if the mixture was ok the hc would be ok even without a cat, but I was wrong. I have no idea what the readings should be. We don't have testing here except in metro areas. So I am unable to help you much with numbers. Darrell ----- Original Message -----

kits is the fact that the original Subaru engine has two catalytic converters. The NOx has always been a problem. Our CARB exemption is not valid without our catalytic converter, you would not have been allowed to run the test in California and it would have failed by a very large margin.

of the oil pan. We have about 10 here already that we are committed to do. I will post a message when we are ready to accept more cores for conversion. There are 3 "prototypes" out there - Ron Bloomquist in one of them. They are looking good, we just have to get a system going so they are not so time consuming, we are doing them "in house" as the local welding shop took 5 hours and did not do the job right. (Sigh).
