  1. Conversor catalítico
  2. Conversor de gases
  3. Equipamento de controle de emissões

Let’s explore each of these informal terms in more detail:

Conversor Catalítico

The expression conversor catalítico is often used colloquially to refer to a catalytic converter. It combines the words “conversor” (converter) and “catalítico” (catalytic), creating a straightforward and easy-to-understand term. For example:
