The effective density and fractal dimension of particles emitted from a light-duty diesel vehicle with a diesel oxidation catalyst
TL;DR: In this paper, a differential mobility analyzer (DMA) and a Couette CPMA were used to measure the effective density and fractal dimension of particles emitted from a light-duty diesel vehicle fitted with a diesel oxidation catalyst (DOC), which was found that at high engine loads, the DOC increased in temperature, sulphate levels in the particulate matter increased, and a transient nucleation mode was observed.
Journal ArticleDOI
New method for particle mass classification—the Couette centrifugal particle mass analyzer
Jason S. Olfert,Nick Collings +1 more
TL;DR: In this article, a new particle mass classifier, the Couette centrifugal particle mass analyzer (CPMA), is described and compared to the existing aerosol particle mass (APM) analyzer.
Journal ArticleDOI
Unipolar diffusion charging of aerosol particles in the transition regime
TL;DR: In this article, a Hewitt-type corona charger was designed for the purpose of the investigation and tested in a Tandem-DMA experimental configuration with particles produced by a combustion aerosol generator (CAG), while the apparatus allowed for the investigation of the effect of pre-existing charge of the aerosols.
Journal ArticleDOI
The fast-response flame ionization detector
TL;DR: The fast-response flame ionization detector has become a widely used instrument for time-resolved hydrocarbon measurement in internal combustion engines as mentioned in this paper, and the characteristics of and working experience with the instrument are reviewed.
