Effect of Stratified Charge Compression Ignition on Emission and Power Output- A Review

Abstract

Abstract The emissions from the vehicles causes for severe air pollution which resulted the development of stringent regulatory norms. Therefore there is a need of improvement in combustion phenomenon to decrease the NOx and PM, as they are directly dependent on combustion. To improve environmental conditions which are directly affecting human health, all automobile companies are endeavouring to satisfy strict emission standards. In this context stratified charge compression ignition (SCCI) engines seems promising and developing its application by incorporating the different types of combustion mode with the help of direct fuel injection and by ranging its capacity to full load condition. Alongside SCCI, a new concept of multi stage induction and Exhaust Gas Recirculation (EGR) can be incorporated in engine to reduce emissions, increase power output and efficiency. Various parameters have been considered to understand the combustion process for developing an engine to meet the requirements. The effect of different variables influencing the combustion process is highlighted.
