基于传统动力源的重型商用车减碳技术

在全球能源危机和温室效应加剧的大环境下,中国向世界承诺减碳目标：2030年前力争实现碳达峰,2060年前力争实现碳中和。作为节能减排的重点,重型商用车的减碳成效是“双碳”征程中的关键。重点介绍基于传统动力源的重型商用车减碳技术,包括内燃机燃烧、低摩擦、智能变速、轻量化、混合动力等技术在内的动力总成领域,以及包括天然气、含氧燃料、氢氨燃料在内的先进燃料领域。通过不同领域的技术发展以及优势互补,更加高效、低碳、清洁的内燃机仍将在重型商用车领域持续发挥重要作用。

Carbon Reduction Technologies for Heavy-Duty Commercial Vehicles Using Conventional Power Sources

Considering the global energy crisis and the greenhouse effect, China has committed to have peak carbon emissions by 2030 and achieve carbon neutrality by 2060. And reducing the carbon emissions from heavy-duty commercial vehicles is crucial to reaching the "double carbon" goals. The paper reviews the carbon reduction technologies for heavy commercial vehicles using conventional power sources, including engine combustion, the intelligent transmission, and the low friction, lightweight and hybrid powertrains.The advanced fuels are discussed as well such as natural gas, oxygenated fuel, hydrogen fuel and ammonia fuel. With technological development and by combining the advantages of different fields, the more efficient,low-carbon and clean internal combustion engines will continue to reduce carbon emissions from heavy-duty commercial vehicles.
