Since last decade automotive exhaust emissions is damaging environment and thereby showing negative impact on health of human beings. It is a big challenge for a catalytic converter to archive tighter norms and standards of pollution control. Technologies developed so far includes improvement in engine design alternative fuels usage additives for fuel exhaust treatment fuel pretreatment , EGR,PCV etc. Among of these one of the most affordable techniques is exhaust treatment by using catalytic converter. It is the best way for abating harmful pollutants like CO, HC, and NO etc. from automotive exhaust. The catalyst in the catalytic converter also plays an important role in reducing emissions. Also the use of non-noble metals like stainless steel as catalyst in the converter has significant results .This paper is dedicated to practical experience of latest technologies development in this view and overcoming of limitations of catalytic converter.
