Abstract
Internal combustion engines consume rich mixture during engine start-up to warm up the catalytic convertor, which is most efficient while operating at 600–800 °C temperature range. The overall life of the catalytic convertor is highly dependent on operating temperature, since noble metals are used for construction. Though modern vehicles are equipped with advanced technology to warm up the catalyst, it does not have a dedicated heat management system for the catalyst. With latest statutory pollution test requirements, the eventual lifespan of a vehicle equipped with factory-fitted catalytic convertor remains uncertain. Hence, a dedicated thermal management system is necessary for the catalytic convertor, which should be economical and compatible with existing vehicles for retro-fitment. This paper focuses on the quest of reducing automotive emissions through technological advancement. A potential solution for emission reduction is proposed by employing more stringent control on the catalyst’s operating temperature, also improving its life.
