Particle measurements were performed in the exhaust of five light-duty vehicles (Euro-3) at +23, -7, and -20^oC ambient temperatures. The characterization included measurements of particle number, active surface area, number size distribution, and mass size distribution. We investigated two port-injection spark-ignition (PISI) vehicles, a direct-injection spark-ignition (DISI) vehicle, a compressed ignition (CI) vehicle with diesel particle filter (DPF), and a CI vehicle without DPF. To minimize sampling effects, particles were directly sampled from the tailpipe with a novel porous tube diluter at controlled sampling parameters. The diluted exhaust was split into two branches to measure either all or only non-volatile particles. Effect of ambient temperature was investigated on particle emission for cold and warmed-up engine. For the gasoline vehicles and the CI vehicle with DPF, the main portion of particle emission was found in the first minutes of the driving cycle at cold engine start. The particle emission of the CI vehicle without DPF was hardly affected by cold engine start. For the PISI vehicles, particle number emissions were superproportionally increased in the diameter size range from 0.1 to 0.3@mm during cold start at low ambient temperature. Based on the particle mass size distribution, the DPF removed smaller particles (dp<0.5@mm) more efficiently than larger particles (dp>0.5@mm). No significant effect of ambient temperature was observed when the engine was warmed up. Peak emission of volatile nanoparticles only took place at specific conditions and was poorly repeatable. Nucleation of particles was predominately observed during or after strong acceleration at high speed and during regeneration of the DPF.
In its performance tests, PACCAR Parts found that the FSX diesel particulate filter cleaning machine got filters 9 percent cleaner than the next best performing machine. A two-stage HEPA filtration system called SootSucker 2 captures ash from each DPF, eliminating the problem of dust settling back on the filters.Filter Breakdown
Dave Moore, CUMTD's Director of Maintenance, explains how the diesel particulate filters easily attach to buses currently in our fleet. Danna Brewster from Engine Control Systems (manufacturer of filters) looks on.
