چکیده انگلیسی
Filter efficiency with regard to the different particle sizes is evaluated by measuring particle size distributions before and after a diesel particulate filter. Results show that sub-10â¯nm particles are not sufficiently removed by the filter. Filter capture is almost complete for particles with sizes greater than 10â¯nm but the collection efficiency decreases to values of the order of 40-50% for sub-10â¯nm particles. This is of concern particularly when using fuels or operating conditions that produce a huge number of sub-10â¯nm particles not removed by the filter and hence emitted from the engine. The objective of the study is not to measure the filtration efficiency of a specific after-treatment system but to give a general warning on the capability of current particulate filters in removing sub-10â¯nm particles.
