Examining the Impact of Diesel Fuel Density Variation on the Performance of Compression Ignition Engines Using the LOTUS Simulation Program

The densities of diesel fuel ratings indicate various crucial factors within the fuel, such as its composition, energy content, and combustion characteristics. The efficacy of diesel engines was evaluated in this study via simulations and experimental comparisons. The study aimed to assess the impact of varying densities of diesel fuel on the performance of diesel engines. The experimental investigation utilized the cutting-edge CI engine, which featured four strokes, a multi-cylinder design, and a fuel system employing indirect infusion with a constant compression ratio. In contrast, the theoretical component utilized version 6.01a of the engineering software "Lotus Engine Simulation" for modelling the identical engine. While maintaining the operating conditions constant, varying loads were applied. It was observed that an increase in the density of fuel diesel led to enhancements in every aspect of engine performance. Furthermore, the simulation outcomes demonstrated high concurrence with the experimental data, with errors not surpassing 3%.
