摘要: 为了对液化天然气(LNG)汽车的经济性做一个全面的分析,探明LNG汽车相对于传统燃油汽车的经济效益,建立了LNG和柴油重型商用车全生命周期经济性差异评价的系统动力学模型,并运用该模型对某企业已生产销售的同级别LNG搅拌车和柴油搅拌车的经济性差异进行实证研究,量化评价了气油价格比、气油耗比、车辆行驶里程等因素变化时两款车的全生命周期经济性差异变化情况。研究结果表明,气油价格比、气油耗比的变化对LNG重型商用车与柴油车的经济效益差异影响明显,并且行驶里程越长,影响越显著。从生命周期角度来看,LNG重型商用车相比于传统柴油重型商用车于使用者而言具有更可观的经济效益。
Abstract: This paper creates a model based on system dynamic to assess the economic difference between Liquefied Natural Gas (LNG) heavy duty commercial vehicles and diesel engine heavy duty com-mercial vehicles. According to this model, a case study has been conducted, which selected the two types of agitating lorry in the same class from market. This research quantitatively evaluates the economic difference while some significant parameters (such as gas/diesel cost ratio, gas/diesel consumption ratio and mileage) are in dynamic situation. In conclusion, the results show the eco-nomic difference between LNG agitating lorry and diesel agitating lorry is much affected by the gas/diesel cost ratio and gas/diesel. Further, the economic effect is more significantly along with the mileage increase.
