Abstract |
A prototype beta gauge instrument was designed and built to measure the mass of particles in exhaust emissions from mobile sources. The sensitivity of the instrument is significantly improved over those that were commercially available. The instrument automatically samples exhaust emissions and computes emission rates in grams per kilometer. All types of mobile sources including catalyst-equipped vehicles and diesel powered vehicles can be sampled by this instrument. The instrument meets the requirements specified in the federal test procedure prescribed in the Federal Register, Part II, Volume 37, Number 221, November 15, 1972. |
