This is total measurement system for PM(Particulate) from diesel engine.
Exhaust gases from diesel engine are controlled flow rate by CFV-CVS.
And gases are mixed with conditioned flesh air.
Diluted gases are captured PM filter of membrane by sampler via PM sampling probe
which installed at the end of tunnel.
After testing, the weight of PM are measured..
Systems of different specifications and methods are available. For details, please contact us.
The Micro-Dilution Tunnel is a PM measurement system by the dilution tunnel advanced to smaller size. High speed linear solenoid valve(responce:0.3sec) is controlled by instantaneous fuel flow and air flow. This device can be mixed separated emission gases and flesh air and can be weighed PM on the filter. This device can be applied steady mode to transient mode with high speed valve.
