Abstract

In this manuscript, the experimental setup was designed and fabricated for optimizing the parameters of a catalytic converter of INDICA V2 exhaust system. Three turbulence intensify devices, namely Swirl Venturi, Swirl Blades and Swirl Contour, were close-fitted before the catalytic converter. The heating element is embedded in its body and thermocouples are used for knowing the performance at various temperature. The experiments were carried out with and without devices also with and without heating of catalytic converter. The emission was characterized by various engine speed. The results showed that catalytic converter effectiveness and efficiency increases when close-fitted the devices before the catalytic converter with heating. Among these devices, Swirl Blades was more effective and it reduces the CO and HC emission by 33.86%, and by 30.56% respectively. Flow Simulation of these devices was carried out using finite volume method. The obtained simulation shows that transport coefficient of catalytic converter enhances using these devices because of high turbulence intensity at the inlet of the catalytic converter. This research concluded that the heating of the catalytic converter and using the Swirl Blades device before it reduces the air pollution significantly of diesel engine motor vehicle.
