Experimental investigation on performance of Campro engine when modify exhaust gas extractor / Mohd Mustaffa Hafiz Khalil

Automotive exhaust system is a device to carry out gases from an engine then discharge it to atmospheres. It is consist of exhaust gas extractor, exhaust pipe, catalytic converter, tail pipe and muffler. The main function of design the exhaust gas extractor is to decrease the flow resistance (also know as back pressure), and to increase the volumetric efficiency of an engine, resulting in a gain in power output. By using Satria Neo 1.6 Campro engine, the comparison of torque and horse power between standard exhaust gas extractor compared to 4-2-1 and 4-1 was obtained. Function of using 4-2-1 and 4-1 are to compare the reducing backpressure of the exhaust system and the increasing of torque and horse power with the standard exhaust gas extractor. This project is used Dynapack Chasis Dynamometer machine to generate the result of torque and horse power between standard exhaust system, 4-2-1 and 4-1. By using this Dynapack Chasis Dynamometer machine, the graph of torque and horse power of the engine are automatically plotted when finish the experiment. This machine also provides all the data needed from this investigation after finish the experiment.
