美国液化天然气车辆燃料系统应用现状

CURRENT STATUS OF FUEL SYSTEM USED BY LNG-DRIVEN VEHICLES IN USA

面对我国大量引进LNG的现实,天然气汽车(LNGV)必将逐渐发展起来,前景可观。为此,介绍了美国液化天然气车辆燃料系统的工作原理和燃料罐产品的规格型号,在设计、制造和应用液化天然气车辆燃料系统过程中适用的规范和标准,以及美国在该系列产品方面所持有的技术专利等。综合分析液化天然气车辆燃料系统后认为,其技术仍有待于进一步完善与发展。

As LNG is imported largely in China, LNG vehicles will be developed gradually and have bright future. It is introduced the working principle of fuel system used by LNG-driven vehicles in USA, the product specifications and types of LNG fuel tanks, the codes and standards to design, manufacture and apply the fuel system used by LNG-driven vehicles, and the technical patents holt in the field. Also, after the fuel system used by LNG-driven vehicles is analyzed comprehensively, it is pointed out the technology of fuel system used by LNG-driven vehicles has to be improved and developed further more.
