Characteristic Analysis of Pollutant Emission from Diesel Locomotive Engine

As the air pollution caused by diesel vehicles goes worse, so non-road vehicles exhaust gas standards are more strict in an foreign countries. There is growing evidence that diesel vehicles could play the important role in determining health effects. Most of the particle number emitted by diesel engines is in the nanopaticle range, D$\_$p/ < 50nm, while most of the mass is in the accumulation mode, 50nm < D$\_$p/ < 1000nm range. The aim of this work was to investigate pollutants in the exhaust of railroad diesel rolling stock under load tests.
