Review on production, characterisation and utilisation of solid fuels in diesel engines

Energy and environment play important role in sustainable development of the world. A continuous research is going on to harness energy from various sources of energy and also reduce the greenhouse gases (GHG) that cause global warning. Despite there is a more focus on utilisation of liquid and gaseous fuels for internal combustion (IC) engine applications, there has also been a continuous interest on utilisation of solid fuels for the same. This paper presents the review of research works pertaining to characterisation and utilisation of different solid fuels such as coal, charcoal, carbon nanotube blended with biofuel, nanoadditive blended fuels, carbon black based fuels and biomass based solid fuels used in compression ignition (CI) engine applications.
