Relationships between Characteristics of Emission Gases and Engine Load Condition of Diesel Locomotive Engine

The air pollution by the diesel locomotives has become serious environmental concern because the emission gases are exhausted without any further treatment. Recently, the public interest on the air pollutants emission reduction technology is increasing due to the establishment of 'Metropolitan Air Quality Preservative Law' and the regulation of local governments on the urban air quality. In this study, we measured the concentration of particulate matters and gaseous pollutants by using a scanning mobility particle sizer, a dust spectrometer, and a stack sampler upon various engine load condition. The results show that the amount of emitted air pollutants increased upon the increase of engine power. The development of new technology to reduce the air pollutants emission is urgently required.
