LNG汽车高原特性研究

Research on Dynamic Property of LNG Vehicle in Highland

从能源短缺危机逐步加剧的背景出发，本着优化当地资源结构，推动LNG汽车的广泛应用，结合高原地区气候特点，全面分析了LNG汽车高原特性的研究现状，深入研究了LNG汽车在海拔3000m以上其功率、转矩和爬坡度等高原特性，并通过增压器及传动系优化，使其高原动力性和经济性得到极大改善，基本实现了破解LNG汽车高原动力性不足及经济性较差的难题，为进一步系统研究高原地区LNG汽车的相关问题提供理论支撑。

From the background of the energy shortage, based on optimization of local resource structure, and wide applica- tion of LNG car, the union plateau climate characteristics, this paper comprehensive analyzed the present research situation of the plateau characteristics of the LNG ear , systematic studied the plateau dynamic performance of the LNG car about the power, torque and climbing capacity at an elevation of 3 000 metres, and took measures to optimize the supercharger matc- hing and the transmission system, made its plateau dynamic performance and fuel economy got a great improvements, really cracked the problem about the plateau dynamic deficiency and the poor economy of the LNG car, in order to provide theo- retical supports to further system research on the related problems of the LNG car in the plateau area.
