Energy policy reviews state that automobiles contribute 25% of the total Carbon dioxide (CO2) emission. The current trend in emission control techniques of automobile exhaust is to reduce CO2 emission. We know that CO2 is a greenhouse gas and it leads to global warming. Conversion of CO2 into carbon and oxygen is an energy-consuming process compared to the catalytic converters. The best way to reduce CO2 is to capture it from the source, store it and use it for industrial applications. To physically capture the CO2 from the engine exhaust, adsorbents like molecular sieves are utilized. In comparison to other CO2 separation methods, adsorption technique consumes less work and energy. Moreover, the sieves can be regenerated, reused and recycled once it is completely saturated. In this research work, zeolite X13 was chosen as a molecular sieve to adsorb CO2 from the exhaust. A chamber was designed to store the zeolite and it is attached to the exhaust manifold. The selected engine was a single-cylinder Briggs and Stratton petrol engine. The experiments were conducted in two…
