Abstract :

This paper includes comparison of the performance and emission results obtained by running the IDI CI engine with and without the turbocharger on diesel fuel. A turbocharger can significantly improve an engine horsepower without significantly increasing its weight. The engine was run at constant rated speed (1000 rpm) and various performance, combustion and emission characteristics were measured at different engine load (25% to 100%) using a loading panel to apply load. A proper test setup was prepared by connecting the engine with Smoke–Meter and 5 Gas–Analyzer. The performance and emission data of the engine was noted at different loads. The performance characteristics (i.e., ake specific fuel consumption and thermal efficiency) were calculated using mathematical relations. The emission characteristics (i.e., smoke opacity, HC, NOx, O2, CO2 and CO) were measured with the help of Smoke meter and 5–Gas Analyzer set–up. The obtained data was plotted on graphs and then compared with each other to give a picture that how a turbocharger fitted to the engine may affect its performance.
