Diesel Emission Rate Caculation (soot amount)

Su Solberg

Hey every one.
I have problem in caculating the soot content in (gram of soot)/(1 liter of exhaust gas).

Euor 4 emission standard of PM emission for HD diesel Engine is 0.02 g/kwh (from wikipedia)

So, If I have an engine rated 200kw, the PM is also 0.02g/kwh, Exhaust flow is 1000CFM
then the soot content in the exhaust flow is (in g/liter):

The amount of soot generated in one hour:
0.02g/kwh * 200kw
=4 g/ hour
=0.0666 g/ min

1000CFM = 28316.8 liter/min

so the PM emission rate is:
(0.0666g/min) / (28316.8liter/min)
= 0.0023mg/ Liter
------------------------------------------------------------
Is the above caculation correct??
Thanks for your help in advance.
