Emission Results
Just got a years MOT! (like waiting outside a maternity ward - but worse!)
Tester said how low the emissions were, looking at previous lots it seems consistent.
The CO was .224 , 3.500 allowed
The HC was 34 , 1200 allowed
Is this typical for a 2litre 8 valver?

Re: Emission Results
Yep, sounds like the motor is in good health. My 8 valver puts out very similar figures usually.

Am I a light sleeper or a heavy sleeper? Well that depends on how much I've had to drink...

Re: Emission Results
Are you absolutely sure you don't have a catalytic converter on yours?

Readings like that show you have a cat

My XE decatted could beat those readings.
A lot of other NE's and XE also have.
Just proves it's running real nice. Good stuff.

Re: Emission Results
These are the readings from my CD auto last year:
CO - 0.81%
HC - 91ppm
It had only done 37,000 miles at that point, it's on 40.500 now and it's MOT is due so I'll see what it gets next week.

Re: Emission Results

Re: Emission Results
It hasn't been tuned or upgraded at all has it because you seem to be getting extraordinary figures for fuel economy and now emissions.
Re: Emission Results
No, totally standard other than a 4 branch exhaust manifold which was recently fitted but previous mots show similar results with the original cast iron manifold.

Re: Emission Results
wish my c20ne was like that it has always struggled to get through the emissions and used to have a new cat each year but I have made a type approved one fit so it will have that on it for the next mot that should sort her out

Re: Emission Results
I just shows all engines are different.
Sure he hasn't stuck the probe up another exhaust
My impreza gets amazing results like that lol
