Abstract
A high sensitivity laser-induced incandescence system is proposed for the detailed characterization of environmental soot. Specifically, innovative approaches have been proposed to (1) reduce the lower detection limit of soot volume fraction and increase the overall measurement range by an order of magnitude from what is currently achievable, and (2) provide PM particle size and number density measurement capability. The proposed LII technique will be capable of real-time particulate matter measurements over any engine transient operation. It will also have orders of magnitude more sensitivity than the gravimetric technique. The wide dynamic range and lower detection limit of LII make this technique a potentially preferred standard instrument for particulate matter measurements. COMMERCIAL APPLICATIONS: The primary application for the LII system is for monitoring the soot particulate emissions from vehicles (diesel and gasoline). Artium believes that the LII instrument could be used for enforcing EPA regulations on particulate emissions. A version of the instrument can also be used for R&D purposes. Specifically, this instrument will help engine manufacturers develop low emission engines and development of products by emissions control equipment manufacturers. Regulators looking for better measurements to develop new emissions regulations will find the LII system to be attractive. It will provide them with real time analytical capabilities for exhaust gas particulates, particularly diesel soot emissions. It is also expected that the LII method can be developed into a field portable compact rugged system that can make roadside measurements of diesel exhaust, be used in test centers for monitoring vehicle emissions, or installed on stationary power plants and operated remotely.
