摘要
面对汽车节能减排的压力和新能源汽车的挑战,基于内燃机的汽车动力系统已经储备了丰富的技术应对措施。短期可以通过优化燃烧、改善充气效率、提高热能管理、减摩、轻量化和降速等手段满足2020年汽车排放和油耗法规的要求,中期通过发动机的电气化实现电机和发动机混合驱动满足2025年和2030年的法规要求,长期采用氩气循环可以实现零排放和卓越的能源效率,前景超越燃料电池。
Plenty of technologies have been developed for automobile engine in coping with the stress of energy-saving and emission reduction and the challenges of new energy vehicles.In short term,the requirements of the regulations on fuel economy and emissions in 2020 can be fulfilled with optimization of combustion,improvement of charge efficiency and thermal management,friction reduction,lightweight and down-speeding.In mid-term from 2025 to 2030 which can be achieved with engine electrification,i.e.petrol-electric hybrid.In long term,zero emission and excellent thermal efficiency can be realized with Argon cycle engine,which has good prospects beyond fuel cells.
