Measurement of the Diesel Exhaust Particle Reduction Effect and Particle Size Distribution in a Transient Cycle Mode with an Installed Diesel Particulate Filter (DPF) 2002-01-1005
Exhaust emissions and particulate matter (PM) from an engine with a conventional continuous regeneration diesel particulate filter (DPF) were measured to evaluate DPF performance under the Japan 13-mode cycle, European Stationary Cycle and various transient cycles: U.S. transient cycle, Japan Automobile Research Institute cycle, and World-wide Heavy Duty Cycle. The emission tendencies with and without DPF under these conditions were clarified. According to these experiments, accumulated PM in the DPF under the driving modes mentioned above has influence on measurement errors. It is necessary to estimate the amount of accumulated PM in the DPF to evaluate the PM reduction rate correctly. This study also measured particle size distribution of diesel exhaust particulates (DEP) downstream of the DPF using an electrical low-pressure impactor (ELPI). As a result, we determined that most of the particles not trapped by the DPF are less than 110nm.
