The present reserves of liquid petroleum fuels indicate that it may not last for longer period. It has become necessary to search for an alternative fuel which can be used in the present engines. Coal, having large reserves and being abundantly available in India comes to be the first choice. This paper considers steps necessary for making ability of normal engines to accept coal fuels. The program for development of the coal fueled engine has a initial stage of feasibility validation. Some specific areas were selected for investigations of this stage. The investigations were proceeded in sequence of study of the literature and systems, solid fuels and preparation specially suitable for conditions in India. The fuel feed system was developed for the above engine. The initial assessment of combustion process of the coal fuels in the engine was performed with the help of analytical and experimental method. The different systems to be used for coal-fueled engines were analysed on the basis of the literature, theoretical and experimental results. The study demonstrates the possibility of operation of these engines in Indian conditions.
