The environmental pollution is one of the major strategic factors for decision-makers both in industry as well as in government. It has been established beyond doubt that the tailpipe emission shows significant effect on environment. It is clear that the vehicles form the predominant source of regulated and unregulated pollution. The environmental degradation all over the world has led to research, which resulted in the development of low emission vehicle and ultra low emission vehicle. In this work, performance of Low Mass Electrically Heated Metal Catalyst (LMEHMC) on the emission from SI engine has been experimentally investigated. Behaviors of chromium and copper oxides under various conditions were studied. It is found that the HC and CO emissions were reduced considerably when LMEHMC used with existing catalytic converter.
