Need help with cat for emissions.
DANMAN - 5/3/12 at 12:00 AM

Hi guys.

I will have to do an emissions test shortly and was wondering what the standards are in the UK and what cats people are using. It is a 99' 918 fireblade engine. Over here in Oz the emission standards I need to pass are:

Max THC (or HC) 0.26g/km
Max NOx 0.63g/km
Max CO 2.1g/km

Any help is greatly appreciated.

Cheers,

Dan.

@Fast idle 2500rpm -3000rpm
Oil temp 60 degrees C

CO less than 0.3%
HC less than 200ppm
Lambda 0.97 to 1.03

@Idle
CO less than 0.5%

No testing of NOx

Cheers

Thanks Davie.

I don't think there is a conversion for ppm to g/km. Has anyone out there had their measurements done in g/km?

Dan.
