Abstracts: There are still key issues that negatively impact on environment. This Project will address the technology behind the catalytic converter as well as the issues and possible solutions that the technology still faces. Car engines produce harmful gases (such as like CO , NO and NO2); and chemical reactions that take place within the catalytic converter change these gases into harmless ones. The converter has failed to address the presence of ‘COLD-START EMISSIONS’ The specifics of the structure of this converter will be essentially the same: a honeycomb structure coated with aluminum oxide and a mixture of catalyst like CeO2 & Porcelain, combined with the mentioned thermal-management and cold-start emissions technology, but the improvements in the effectiveness of the product will be substantial. This future catalytic converter will incorporate phase change material (PCM) as well as vacuum insulation. The improved catalytic converter will retain heat so that there is no such thing as cold-start emissions. In fact, a true “cold” start would be highly unlikely to occur on a regular basis due to the converter’s heat retention systems. As well as being environmentally friendly, the automobile industry will benefit from this new catalytic converter. Automobile manufacturers will no longer be responsible for so much environmental damage due to the advanced converter and the problem of cold-start emissions will be solved. Such as to try a something beneficial to helpful to environment as put it CO2 absorber pipe in the end of the converter which is absorb CO2 and may be 80% effective system and made this device Eco-Friendly. For absorb this gas use Zeolite material inside the pipes which is made the environment clean. Catalytic converter designed and through CFD (ANSYS 14.0 software - MAGNITUDE) analysis with limited back pressure flow analysis. In CFD analysis, various models with different wire mesh grid size combinations were simulated using the appropriate boundary conditions and fluid properties specified to the system with suitable assumptions. The back pressure variations in various models and the flow of the gas in the substrate were discussed in.
