Effects on Emission Using Caco3 Based Catalytic Converter on Four Stroke Single Cylinder Petrol Engine

Petrol engines are widely used automobile application for private and commercial transportation use because of its good fuel efficiency and durability. But, petrol engine emissions are extremely harmful to human health and to the environment and are at targets for its reduction, especially in city & urban area because most of the petrol engines are used in human populated areas. There are many reports of oxidation catalysts in the exhaust system of petrol engines, which had proven significant reductions in HC, PM and CO with oxidation catalysts. However, its advantages depend upon engine loads / exhaust temperatures and periodical cleaning of converter cell. Normally these converters have 5-6 years of life and the performance deteriorates with impurities deposition on basic metal surface. Calcium carbonate is naturally available good resource for its chemical reactivity and performance for exhaust gas treatment.
