摘要/Abstract

摘要：

从生命周期视角，研究了液化天然气（liquefied natural gas，LNG）商用车与柴油商用车在材料制备、零部件加工制造、整车装配、使用、回收利用等整个生命周期各阶段的能源消耗差异，建立了LNG商用车与柴油商用车能耗差异评价模型，并利用该模型对某LNG搅拌车和柴油搅拌车的直接能耗差异和生命周期总能耗差异进行了实证研究。结果表明，LNG搅拌车具有节能优势。

Abstract:

According to the life cycle theory, energy consumption differences of the LNG and diesel commercial vehicles were comprehensively studied from material preparation, part manufacturing, vehicle assembly, use, recycling stage. An evaluation model of the differences between LNG and diesel commercial vehicles' life cycle energy consumption was established. And differences in the direct energy consumption and life cycle of the total energy consumption of the LNG mixer truck and diesel mixer truck were calculated by using the model. The results show that the LNG mixer truck has a certain life cycle energy-saving advantages.

Key words: liquefied natural gas (LNG), diesel, commercial vehicle, life cycle assessment, energy consumption
