IC engine have proved to be promising technological advancement in the field of the transportation. With the invention of automobiles there is continuous development and revolution was seen in the transportation sector. IC engine uses the hydrocarbon fuels for combustion and develops the required propulsion power for the automobiles. Along with the advantages of the IC engine there are also some of the effects which are observed on the environment due to the emissions generated by the combustion of the hydrocarbons. This effect was observed and came into light during the early nineties and it made the researchers in the field to find the ways to reduce the pollution generated due to combustion of the hydrocarbon fuels. Passenger vehicles are powered by the gasoline whereas heavy transportation vehicle are powered by the Diesel fuel due to space availability for the larger size engine accommodation and high power requirement. It is found that efficiency of the Diesel engine is less than the gasoline engine and it emits some of the more harmful pollutants due to dynamic driving cycle. So many different ways were implemented to reduce pollution and one of the methods in research is the use of the alternative fuels, fuels blend and most recent research is addition of the Nano-Additives in the fuels to improve the combustion efficiency and reduce the emissions. This paper summarizes the recent progress and research on performance, combustion and emission characteristics of CI engine by using the Plastic oils and other alternative fuels doped with nano additives.
