One-dimensional thermodynamic model development for engine performance, combustion and emissions analysis using diesel and two paraffin fuels

A one-dimensional (1-D) thermodynamic model for engine performance, combustion and emissions using a regular diesel and two paraffin fuels (decane and dodecane) were developed using a GT-Suite simulation software. The engine performance, combustion and emission parameters for two paraffin fuels were analysed and compared with that of regular diesel. Thermal efficiency and specific fuel consumption were considered for engine performance analysis. Amongst the combustion parameters, in-cylinder pressure, rate of heat release, maximum temperature, start of combustion, ignition delay, 50% burned crank angle, 50% burned duration, and volumetric efficiency and excess air ratio were taken into consideration for analysis. Finally, specific oxides of nitrogen (NOx), and specific soot emissions were considered for emission analysis. Based on the engine performance, combustion and emissions analysis of all three fuels, it was found that decane and dodecane can be used as alternative fuels for diesel engine. © 2019 The Authors.
