The diesel engine is one of the most widely employed units for power generation and it alone consumes a large amount of entire petroleum. On the other hand, it is the major contributor of particulate matter (PM) emission into the outdoor environment. Particulate matter (PM) is the amalgamation of different particles with liquid droplets and can be generated directly from the source or can be formed through atmospheric chemistry. Particulate matter (PM) generation is harmful to human health in numerous ways discussed in this paper. There is no threshold limit for particulate matter (PM) exposure for human beings. However different organizations such as US EPA and ASHRAE have set limits for acceptable concentration of particulate matter (PM) exposure.
