Abstract: 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. The paper has gone through the effects of different types of biodiesel fuel from the literature on quantity of particulate matter (PM). It was found that both the existence of high concentration of the Oxegentaed atoms and the robust dual bonds between it and the Carbon in the biodiesel creates less percentage of soot, giving lower PM emissions amount for the biofuel combustion. However, rising the length of fatty acid chain impacts remarkable growth in microscopic particle mode and there is a growth in the number of microscopic particles, which is a real crisis for running engines with biofuels due to the smaller particles sized being more dangerous to human health.
