Performance and Brake Specific Fuel Cost of Constant Speed Diesel Engine for Acetylene As Alternative Fuel

Abstract

Historical growth for development of power to fulfil the demands, together provides a challenge for depletion of fossil fuels. The internal combustion engines have a major share used to develop power. To fulfil the increasing demands, many researchers worked on diesel engine with biodiesel blends derived from edible and non-edible oils as an alternative fuel. Some researcher’s experimented gaseous fuels along with diesel also in which diesel will be primary fuel and gaseous fuels like acetylene will be secondary fuel. Increased rates of pollutants again required more focus in modification of engine sub-assemblies. The present study carried out to find the cost effectiveness while the constant speed diesel engine supplied 2 liter per minute flow rate of acetylene at different compression ratios. It realized that the brake specific fuel consumption and required cost to operate the engine, in case of duel fuel mode operation will be less for the compression ratio of 17. It was also noted that for idling or low load the operation of engine will be costly with duel fuel mode of operation and for maximum load the cost of operation will be barely same as the operation on only diesel. The results from performance analysis states that in duel fuel mode of operation by decreasing compression ratio to 17, no change in power out with decreased sound pressure. Also from emission analysis decreased CO2, HC emission found than only diesel operation.
