Combustion and Performance Analysis of a Dual-fuel Diesel Engine Using Producer Gas

Abstract

The researchers around the globe are trying to overcome energy crisis by developing suitable alternative energy source. In this work, combustion and performance analysis of a diesel engine was studied running in dual-fuel mode using producer gas. The experiment shows lower engine performance like brake thermal efficiency, increased brake specific fuel consumption and exhaust gas temperature in dual-fuel run as compared to diesel alone run. Combustion characteristics like cylinder pressure, mass fraction burned, mean combustion temperature and net heat release were also found to be deteriorated in presence of producer gas. The peak value of cylinder pressure and net heat release were noticed slightly away from the top dead center. The experimentation indicates that combustion improving techniques should be employed to enhance the performance of the dual-fuel engine to run with producer gas.
