摘　　要：分析了三种清洁排放汽车——压缩空气汽车、液氮汽车和LNG汽车的特点。提出一种利用气体动力循环的LNG双动力汽车系统,将开式朗肯循环与内燃机循环结合,优势互补。结果表明,LNG双动力汽车系统中的天然气开式朗肯循环输出功远高于液氮汽车。LNG双动力气车系统可用能较普通LNG汽车增加9.82%,且对环境没有污染,节能环保效果明显。The features of three clean emission vehicles, compressed-air-powered vehicle, liquid nitrogen vehicle and LNG vehicle, were analyzed. An LNG dual power vehicle system adopting air-powered cycle was proposed which combined an opening Rankine cycle with a combustion engine cycle. The results show that the power output of the natural gas opening Rankine cycle in the LNG dual power vehicle system was significantly greater than that of the liquid nitrogen vehicle. Compared with ordinary LNG vehicles, the available energy yielded in the LNG dual power vehicle system increased by 9.82%.
