Performance Investigation of Dual Fuel Engine: A Technical Review

The concerns about the diesel engine’s emissions and the reduced availability of fuel oil, led to the adoption of alternative fuels on diesel engines have been found to be an attractive solution. The application of natural gas is a veiy promising and veiy attractive because of its abundant availability in nature, low cost and clean burning quality for use as an alternative fuel on compression ignition engine. The purpose of this study is to explain the working principle of dual fuel engines. In this technical study, will be discussed performance of dual fuel engine and compared with diesel engine. Based on the literature, it has been found that engine power and engine torque decrease in dual fuel mode but power loss can be reduced or recovered by changing some operating parameters. Brake Thermal Efficiency (BTE) in dual fuel mode is lower at low and medium loads while under high engine load conditions, equal to or slightly higher when compared to normal diesel mode.
