我国汽车动力流体传动与余热利用的研究与发展

Study and Development of Vehicle Fluid-transmission and Recovery of Waste Heat in China

概要地介绍了我国汽车动力流体传动技术暨液力混合动力公交车、液压自由活塞发动机和气动汽车的最新研究成果.针对现有液压储能装置能量密度过小的缺点,提出了采用汽—液两相储能介质、高比强度复合材料、内燃机余热利用等改进措施.以此为基础,探讨了汽车四种典型路况的驱动方案.

The paper briefly introduces the recent study results of vehicle fluid transmission in china the hydraulic hybrid city bus, hydraulic free piston engines and pneumatic vehicles. In order to solve the problem that the energy density of hydraulic accumulator is too small, the paper proposes that vapor-liquid two-phase medium of energy storage and high specific strength material should be adopted for the accumulator. Based on what mentioned above, the vehicle fluid transmission plans fit for four kinds of road conditions which include roads of cities, roads between cities and countries, road of high speed, and roads of mountainous regions.
