Engine Emissions Particle Measurement
St. Paul , Minnesota
There have been recent changes in regulations for engine emissions. The mass emission limits have be lowered to the point where filter measurements are reaching their limits of resolution. To achieve lower emission levels it is useful to get more information about the emissions to better understand the combustion process and to get real time measurements to determine when emission peaks occur. In this talk a number of instruments will be described that can be used for engine emission measurements. They include instruments for counting particles, measuring size distributions and measuring real time mass.
