PERFORMANCE & EMISSION OPTIMIZATION OF SINGLE CYLINDER DIESEL ENGINE TO MEET BS-IV NORMS

Abstract

The growing cities, sharp increasing traffic, trajectory growth, rapid economic development and industrialization, and higher levels of energy consumption has resulted an increase of pollution load in the environment. It is also accepted that automobiles have emerged as a critical source of air pollution in the developing world. Realizing the gravity of the problem, steps are being taken to introduce better technologies, better fuel quality, shift to environment friendly fuels, and mass transit system for the control of environmental pollution in urban areas. Electronic diesel control, use of electronic FIE with increase in injection pressures and flexibility in injection control has changed the image of diesel engine. Engine optimization will lead to the better power with the better fuel economy which accomplish the urban living standard and care of the environment. Conventional fuel injection system was unable to fulfilment of this requirement, so it is necessity to modify fuel injection system along with vehicle after exhaust after treatment devices. Performance and Emission was optimized by using ETAS-INCA software. For the subject Bs-III engine, capacity is increased 50cc and certain modifications done. After proper optimization, with EGR ON the power value increased by 8.776% and torque value increased by 16.667% with respect to previous BS-III engine. Since the introduction of the new auxiliary system shows the gradual effect on the engine. According to the BS-IV norms the taper exhaust re-circulated by Oil Mist Separator (OMS) and to increase the performance the implementation of EGR Cooler is done. Also the BS-IV norms are achieved successfully in chassis dynamometer.
