柴油中颗粒粒径,体积分数检测方案(烟气分析仪)

During the last decade particulate matter emission regulation have mandated lower emissions. Future regulations (e.g. EURO 5) will require even lower vehicle emissions. A large reduction in total particulate mass will also create new problems in accurate measurement. Further the calibration of engine maps to interface with soot trap optimisation will require transient data which is certainly beyond current gravimetric procedures. Laser-Induced Incandescence is a technique capable of measuring accurately and near instantaneously particulate matter mass and soot primary particle diameter. LII offers as well the ability to operate in raw exhausts where hydrocarbon loading and vapours often affect other instruments. This poster presents the self-calibrated LII technique invented by the National Research Council, Canada and currently under development in collaboration with Cranfield University. We present measurements taken at Millbrook Proving Ground Emission Test Chamber on a Vauxhall Frontera® and a Dennis Dart® bus following the Euro 4 cycle procedure and the Millbrook London Bus Transport Cycle Procedure. This poster includes also a demonstration of real-time raw exhaust measurement between the exhaust and the particulate trap of a London Bus and a comparison with instruments available within the test facility.
