Todos os veículos com motores de combustão interna estão equipados com um conversor catalítico. Esta parte foi concebida para reduzir o impacto dos gases de escape sobre o ambiente. O tipo e funcionalidade do dispositivo depende da marca, modelo e ano de fabrico do automóvel. Mas o seu princípio de funcionamento é semelhante, e as próprias peças tornam-se inutilizáveis após um certo período de utilização.

Se o diagnóstico tiver demonstrado que a peça não pode ser reparada, há sempre uma oportunidade de a vender com lucro. AutoCatalystMarket Brasil vende velhos conversores catalíticos. Contacte o seu representante para uma estimativa do custo do seu conversor catalítico.

Como funciona o conversor catalítico?

O elemento principal do catalisador é um favo de mel cerâmico revestido com uma fina camada de metais caros. O lítio, platina e ródio são utilizados para revestir os favos de mel. O conversor catalítico limpo os gases de escape por pré-oxidação.

Para realizar este processo, existe um sensor em frente ao conversor catalítico que detecta o nível de oxigénio nos gases de escape. Devido aos valores registados, o sistema ajusta o funcionamento do motor de modo a que haja oxigénio suficiente no escape para neutralizar os elementos nocivos no conversor catalítico.

Um segundo sensor (sonda lambda) também é instalado na maioria dos veículos e mede o nível de oxigénio na saída do conversor catalítico. Monitoriza a forma como decorreu o processo de limpeza de emissões.

Substituir ou apagar?

Quando um catalisador se avaria, os proprietários de automóveis são confrontados com a questão: substituir a peça gasta ou simplesmente cortá-la? E esta questão não é irrazoável, uma vez que a peça custa muito dinheiro.

Consequências da remoção do conversor catalítico:

• mais substâncias nocivas serão libertadas para o ambiente;
• o nível de ruído do motor irá aumentar;
• tornar-se-á impossível passar num teste técnico porque o desempenho ambiental do motor não estará à altura das normas;
• se a garantia da máquina ou do motor ainda não tiver expirado, o documento tornar-se-á inválido.

Estes factores podem fazer os proprietários de carros mais caros pensar duas vezes. Mas o custo da peça em carros baratos e mais antigos faz com que os seus proprietários se recusem a substituir o conversor catalítico. A sua remoção parece ser uma solução mais viável.

Embora esta opção seja adequada para motores Euro-2, a remoção do conversor catalítico em modelos mais recentes pode ter consequências indesejáveis. O sistema de escape de alguns veículos é mesmo composto por vários conversores catalíticos. Isto aumenta ainda mais o custo da sua substituição.

Os conversores catalíticos modernos estão normalmente equipados com sensores de oxigénio. A sua ausência irá afetar o funcionamento do motor ou impedi-lo de arrancar de todo. Por conseguinte, ao remover o catalisador, é aconselhável utilizar os serviços de especialistas. Cortar este elemento por si só pode danificar o veículo. Além disso, a sua remoção pode exigir a instalação de uma sonda lambda como para-choques.
