摘　　要：汽油的挥发程度是油品管理与使用中需要关注的重要问题,它与油品质量息息相关,并直接影响汽车性能以及环境状况。当汽油挥发程度偏高时,在储存环节会造成油品的大量损失,同时带来不容忽视的安全隐患,可能引发火灾或爆炸等事故,同时在环保方面,其挥发物会加剧环境污染。在实际使用场景下,过高的挥发度会干扰发动机的正常启动,使燃烧效率大打折扣,进而导致汽车动力减弱、油耗增加等问题。本研究通过系统地收集汽油在不同挥发程度下各项检测数据,深入分析发现,汽油挥发会致使汽油馏程、蒸气压、烃类、氧含量等重要指标出现显著的变化。这些研究成果可为成品油销售公司在汽油的储存、运输以及销售等环节,提供科学依据,帮助优化管理流程,减少损耗并降低风险,实现更高效、更环保的运营模式。The degree of evaporation of gasoline is an important issue that needs to be paid attention to in the management and use of oil products,which is closely related to the quality of oil products and directly affects the performance of vehicles and the environment.When the evaporation degree of gasoline is too high,it will cause a lot of oil loss in storage and bring serious safety hazards that cannot be ignored,which may lead to accidents such as fire or explosion.At the same time,its volatile matter will aggravate environmental pollution.In actual use scenarios,excessive evaporation degree will interfere with the normal starting of the engine and seriously reduce the combustion efficiency,resulting in problems such as reduced vehicle power and increased fuel consumption.This study systematically collected various detection data of gasoline under different evaporation degrees and conducted in-depth analysis to find that the evaporation of gasoline will cause significant changes in important indicators such as gasoline distillation range,vapor pressure,hydrocarbons,and oxygen content.These research findings can provide scientific basis for finished oil sales companies in the storage,transportation,and sales of gasoline,helping to optimize management processes,reduce losses and risks,and achieve more efficient and environmentally friendly operation modes.
