Dismantling:

SAMPLING OF EXHAUST EMISSIONS
After the engine is installed in the equipment and placed in service, the sampling of
exhaust emissions can be performed in a way that prevents diluting the exhaust sample
with ambient air as follows:
• Remove the exhaust mesh insert, if so fitted, as described in chapter 5.3.5.
• The sampling probe for measuring the emissions can be put into the exhaust silencer
outlet. There are no additional pipes or clamps needed for measuring the undiluted
exhaust sample.
