Por que o carro liga com a rotação alta? Quando você dá a partida a frio, o computador do carro (ECU) injeta mais combustível e eleva a rotação (RPM) de propósito. O objetivo principal é fazer o catalisador aquecer o mais rápido possível. O catalisador só consegue filtrar os gases poluentes de forma eficiente quando atinge sua temperatura ideal de trabalho (entre \bm{300^\circ\text{C}} e \bm{800^\circ\text{C}}). Assim que ele esquenta, a rotação do motor cai para o normal. 🇺🇸 English Why does
