天然气汽车发展现状及趋势
摘要 在能源结构优化、环境污染控制、气候变化约束的驱动下,天然气汽车具有较高的发展潜力.天然气汽车动力源主要有4种形式:压缩天然气(CNG)单一燃料发动机(燃料是天然气或天然气掺氢)、CNG汽油两用燃料发动机、CNG柴油双燃料发动机、液化天然气(LNG)发动机.天然气汽车主要应用于我国交通运输行业营运车辆,主要以CNG汽车、CNG/汽油两用燃料汽车的形式在出租车中应用;以CNG汽车形式在公交车中应用;以LNG汽车形式在重卡中应用.天然气汽车未来应该大力发展LNG重卡;保持CNG公交客车比例,并推动气电混合动力公交的发展;将两用燃料出租车逐步替换为CNG汽车.发展天然气汽车对我国能源结构优化、交通运输节能减排具有重要意义.
Abstract:
Optimization of energy structure, control of environment pollution, and constraint of climate change drive the development of CNG automobiles. There are four engine modes: CNG engine fueled with CNG or mixture of CNG and H2, CNG/gasoline bi-fuel engine, CNG/diesel dual fuel engine, and LNG engine. Natural gas automobiles are mainly applied in transportation sector, with CNG automobiles, CNG/gasoline bi-fuel automobiles for taxis, with CNG automobiles for buses, and with LNG automobiles for heavy duty trucks. In the future, LNG heavy duty trucks should be developed; CNG buses and CNG electric hybrid buses should be developed; bi-fuel taxis should be substituted with CNG taxis. Natural gas automobiles play a significant role in optimization of energy structure and energy saving and emission reduction of transportation sector.
