Abstract

An emissions measurement system capable of providing an accurate, real-time estimate of particle number (PN)/particulate matter (PM) within exhaust is disclosed. The system is capable of accurately differentiating the size and composition of PM/PN by synchronizing dissimilarly configured sensors. The exhaust may be generated by an internal combustion engine, in which case the system may be sequentially connected to the exhaust from the internal combustion engine.
