ABSTRACT This research focuses on reducing the toxic emissions from the exhaust by installing a turbulence enhancement unit just before the three-way catalytic converter. This unit creates turbulence in the gases flowing through the combustion chamber when fitted with the Tata Indica V2 diesel engine (1405cc). Turbulence leads to the rising in the contact area of the exhaust gases going to the catalytic converter for the reactions to take place. Experimentally, it was found that swirl venturi gives the best results in the overall emission test. Although the overall best device is swirl venturi, swirl blades also give better results on higher rpm of the engine. This paper shows the detailed research on the emission test performed.
