摘　　要：汽油机动车目前仍然是民用机动车的主要组成部分,由于汽油质量问题导致的机动车尾气排放污染,已经引起人们的广泛关注。汽油辛烷值标准物质的研制,对加强汽油质量安全监管、促进大气污染防治和保障人民群众身体健康方面具有重要作用。随着我国车用汽油国家标准的更新,我国现有的汽油辛烷值有证标准物质历经发展,逐渐满足人们对汽油品质提升的需求。通过对国内车用汽油标号及抗爆性技术要求进行较为全面的总结归纳,对影响汽油辛烷值的组分、添加剂等物质及其环境影响进行阐述,旨在分析我国在汽油辛烷值标准物质研制方面的现状、趋势和发展方向。Gasoline motor vehicles are still the main component of civil motor vehicles, and the pollution of motor vehicle exhaust emissions caused by gasoline quality problems has caused widespread concern. The development of the gasoline octane number certified reference materials(CRMs) plays an essential role in strengthening the quality supervision of gasoline, promoting the prevention and control of atmospheric pollution, and ensuring people’s health. With the renewal of the National Standard of Gasoline for Motor Vehicles, the existing gasoline octane number CRMs have been developed to meet people’s demand for an improvement of gasoline quality. Based on a comprehensive summary of gasoline grades and knock resistance technical standards, the components, additives and other ingredients that affect the octane number of gasoline and their environmental impact are described, aiming at analyzing the status quo, trend and future direction of the certified reference materials.
