日前,汽车排出的有害物对环境的污染日趋严重,成为人们亟待解决的问题。车辆设计专家Peter Pellandine日前指出,燃油蒸汽发动机可用于公共汽车、拖拉机和卡车这类低速度车辆中,而且对环境的危害比起内燃机要小得多。目前世界上蒸汽汽年的最快速度为121英里/小时, A few days ago, the environmental pollution caused by harmful substances emitted by automobiles has become increasingly serious and has become a problem that people urgently need to solve. Peter Pellandine, a vehicle design expert, pointed out recently that fuel-powered steam engines can be used in low-speed vehicles such as buses, tractors and trucks, and that their environmental impact is much smaller than that of internal combustion engines. The fastest steam year in the world is 121 mph.
