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.
Claims24
An emissions measurement system comprising:
- an emissions sample inlet;
- at least three sensors connected to the emissions sample inlet, wherein the sensors are sequentially connected in a linear arrangement and wherein each of the at least three sensors is configured to perform a different measurement of a sample;
- and
- an emissions sample outlet connected to the at least three sensors.
A method of measuring emissions comprising:
- linearly transporting an emissions sample through at least three sensors, wherein each of the sensors is configured to perform a different measurement of the emissions sample;
- and
- calculating either a particle number (PN) or particulate matter (PM) measurement for the emissions sample using data from the sensors.
