Diesel Emission Rate Caculation (soot amount)

  1. Feb 20, 2009 #1
    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.
