Measurement of Particulate Emissions from GDI Engines
Overview
Measuring the number of particles is far more complicated than measuring the mass, since particles may be involved in mechanisms such as deposition, mutation, particle-to-gas conversion, etc. during the exhaust process, which could then lead to a dramatic change in their total number. Various number-based particulate measurement instruments are commercially available as research tools. However, valid measurement requires in-depth knowledge of numerous experimental variables with the central objective being that the results should be representative of real exhaust particulate emission. It is also desirable to resolve the composition and the morphology of the particulate emission, which could enable researchers to model the formation of particulate matter and to understand the impact on health.
