“…Internal combustion engines use the exhaust stroke to expel the spent gases, via the exhaust system, where the harmful emissions are then passed through a muffler-type looking device which is the catalytic converter [12,21]. Components of the spent gases consist of unburned hydrocarbons, NO, and CO [21]. As mentioned above, the main purpose of the catalytic converter is to reduce the original harmful emissions to the most acceptable levels, by the means of catalyst controlled chemical reactions.…”

“…Um dos dispositivos mais antigos desenvolvidos para essa finalidade e utilizado até os dias atuais pela indústria automobilística mundial é o catalisador, também denominado como conversor catalítico, elemento utilizado pelas montadoras de veículos brasileiras desde o início da década de 90 para atendimento à fase L2 do Programa de Controle de Emissões Veiculares (Proconve), representando uma das alternativas mais eficazes ao controle das emissões de HC, CO e NOx 29 . Os conversores catalíticos são construídos em formato de colmeia que pode ser revestida com os metais nobres platina, paládio, rádio e molibdênio, cuja função é favorecer a conversão de gases poluentes nocivos ao meio ambiente em gases não poluentes 30 . Logo, os catalisadores são instalados após o sistema de escape dos veículos de forma que os gases provenientes do coletor de escape dos motores fluem por dentro da colmeia.…”
