Nas duas \u00faltimas d\u00e9cadas, a ind\u00fastria automotiva vem equilibrando dois objetivos conflitantes: reduzir as emiss\u00f5es e melhorar a efici\u00eancia do consumo de combust\u00edvel. At\u00e9 agora, as emiss\u00f5es foram a prioridade, mas com os motores diesel de hoje mais limpos do que nunca, toda a ind\u00fastria est\u00e1 mudando o foco para o consumo de combust\u00edvel.<\/p>\n

 <\/p>\n

Desde o in\u00edcio da d\u00e9cada de 1990, as normas e regulamenta\u00e7\u00f5es de emiss\u00e3o, como o Euro e o US10, viram as emiss\u00f5es de NOx (\u00d3xidos de Nitrog\u00eanio) diminu\u00edrem mais de 95%. No entanto, estas redu\u00e7\u00f5es tamb\u00e9m tiveram um efeito negativo sobre a efici\u00eancia do motor devido \u00e0 conta entre emiss\u00e3o de NOx e consumo de combust\u00edvel.<\/p>\n

 <\/p>\n

A maioria dos OEMs (fabricantes de equipamentos originais) conseguiram obter ganhos de efici\u00eancia em outras \u00e1reas para compensar isso, de modo que o consumo geral de combust\u00edvel n\u00e3o aumentou. No entanto, isso significou que o ritmo de redu\u00e7\u00e3o do consumo de combust\u00edvel diminuiu nos \u00faltimos anos. At\u00e9 agora. Com as emiss\u00f5es t\u00e3o baixas, as autoridades governamentais e reguladores em todo o mundo est\u00e3o deslocando a sua aten\u00e7\u00e3o sobre as emiss\u00f5es de CO2 e efici\u00eancia de combust\u00edvel.<\/p>\n

 <\/p>\n

Por exemplo, nos EUA, foram introduzidas as normas de emiss\u00f5es de fase dois para ve\u00edculos pesados. Segundo os novos regulamentos, todos os caminh\u00f5es constru\u00eddos a partir de 2021 precisar\u00e3o emitir pelo menos 24% menos CO2 do que os modelos 2018. Legisla\u00e7\u00e3o semelhante tamb\u00e9m est\u00e1 sendo colocada em pr\u00e1tica na UE, Jap\u00e3o e China. A Comiss\u00e3o Europeia desenvolveu a VECTO, uma ferramenta de simula\u00e7\u00e3o por computador para medir as emiss\u00f5es de CO2, que permitir\u00e1 certificar, monitorar e comparar o consumo de combust\u00edvel de diferentes modelos de caminh\u00f5es.<\/p>\n

 <\/p>\n

Mas como isso afetar\u00e1 o desenvolvimento do caminh\u00e3o? O programa SuperTruck I do Departamento de Energia dos EUA pode oferecer um vislumbre do poss\u00edvel futuro de caminh\u00f5es pesados. O programa re\u00fane parceiros industriais e fabricantes, para desenvolver e conceber novos conceitos com o objetivo de aumentar a efici\u00eancia do transporte de mercadorias em 50%. Algumas das melhorias incluem o uso de materiais leves, superf\u00edcies aerodin\u00e2micas altamente projetadas, pneus de baixa resist\u00eancia \u00e0 rolagem, uso de equipamentos de otimiza\u00e7\u00e3o de in\u00e9rcia e sistemas de recupera\u00e7\u00e3o de calor residual.
