纯天然气发动机试验台的开发与研究

Development and Research of pure gas engine test stand

天然气汽车作为新型代用燃料汽车,因其节能环保和经济安全被重点推广使用。随着天然气汽车的大范围应用,汽车修理人员无法快速、准确地判断故障所在这一问题逐渐暴露,尤其是电控技术的大量应用,天然气发动机的故障诊断变得愈加困难。因此,研究纯天然气发动机试验台已经成为一件十分紧迫的事情。文章以上柴、南内纯天然气发动机为研究对象,介绍了纯天然气发动机试验台的结构,重点分析了试验台在使用时的技术参数和性能特点,为纯天然气发动机检测提供了重要理论依据。

Natural gas vehicles as a new alternative fuel vehicles, because of energy saving and environmental protection, economic security is focused on promoting the use. With the wide range of applications of natural gas vehicles, auto repair personnel can＇t quickly and accurately determine the fault lies the problem gradually exposed, particularly large number of applications electronic control technology, natural gas engine fault diagnosis becomes more difficult. Therefore, the study of pure natural gas engine test stand has become a very urgent matter. Shang Chai,Nan Nei pure natural gas engine for the study, describes the structure of the pure gas engine test stand, focuses on the test bench in the use of technical parameters and performance characteristics. It provides an important theoretical basis for pure gas engine testing.
