EXPERIMENTAL INVESTIGATION OF DIESEL ENGINE USING GOBAR GAS BLENDS

Vehicular exhaust fouling of the environment has already become a serious problem in the western countries and is growing menace in the developing countries like India.They are exhausting huge quantities of harmful pollutants in urban areas. Since the 1973 international oil crisis and the related increase in the price of fossil fuels, all countries of the world have been developing increased effort to open up a new energy source. An alternative approach of getting gas fuels is through an anaerobic fermentation of wet placental mammal waste to provide Gobar Gas (50 to 70% of CH4 and remaining CO2).This gas particular significant for India because of its large scale and best population.Production of Gobar Gas from supposedly worthless organic waste which is easily available and as yet unused source of energy. Recent advances in the storage and transportation of Gobar Gas had it made it now profitably use it as a fuel for C.I.Engines. It can be either carried as liquefied gas or stored in a compressed gas cylinder.The primary advantages of these gaseous fuels are its ability to operate the engine on a lean mixture, thereby reducing exhaust hydrocarbon and CO2 concentration in the effluent of the engine. It gives less deposit and shows clean burning characteristics and as compared to petrol and diesel oil. The ignition temperature of Gobar Gas is higher than many other fuels.
