What engine revs for sva emissions?
Ive just had a my car gas analysed at an mot station and they were: CO .0003, PPM 5 and the lambda just made below 1.03 at 3500 to 4500 rpm. What
engine revs are used for sva emissions . Do you think this would pass sva?
Cheers Des

dont hold me to this but i though it was 3/4 of your max revs, such as if your engine does 8000rpm they test at 6000 but i might be wrong/confusing
this with motorsport...
cant say for sure...

The 3/4 max revs is for the noise test . Mot test levels are around 3,000 rpm

as mentioned , the rpm for emissions is any where from 2500 rpm to 3000 , the max for lambda is 1.03 so a little close there but once the revs are
between those limits then the reading should come down , ave reading is 1.00 on lambda.

Just to confirm
BET / CAT Test
Fast idle (2500-3000rpm)
CO<=0.3%
HC<=200ppm
Lambda 0.97-1.03
Idle Test (450-1500rpm)
CO<=0.5%
(From Mar '04 SVA manual)
Noise is at 3/4 max power as already said
