The present book is a result of experimental work carried out on a spark- ignition engine fueled with Bio-gas. The biogas was obtained by the anaerobic digestion of Gobar(Cow-Dung). The investigations are made to determine the difference in the performance of the engine due the the purification of raw bio-gas. It is a good work carried out by the author which can further be studied by using various other biogas cleaning methods.
