An emissions measurement system capable of providing an accurate, real-time measurement of an emissions sample is disclosed. 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. The emissions measurement system can include a laser light opacity sensor, a light scattering sensor, and a particle ionization sensor.

Device and method for measuring emissions with a linear arrangement of sensors

An apparatus and method for generating a controlled, predictable, reproducible and variable-size distribution of particulate matter (PM), particle number (PN) and/or facsimile/simulation, derived from vaporizing and condensing a specialized liquid, utilizing a vapor delivery device; a filter capability so as to remove a significant amount of ambient PM/PN as a secondary calibration process for the identification of fine and ultra-fine particles (e.g., 0.3 micrometers and smaller) as well as a computer-controlled ability to perform a pre-determined series of calibration routines, housed in a container.

Particulate calibration and generation simulator for particle measurement and number

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.
