摘要
汽油辛烷值是衡量汽油在气缸内抗爆震燃烧能力的一种数字指标,可用辛烷值测定仪快速测量。汽油辛烷值测量结果的准确可靠,既可最大限度实现汽油的动力经济性能,也可提升驾驶安全性。本文探讨了用车用汽油辛烷值标准物质对基于介电常数法的车用汽油辛烷值测定仪进行校准,并对校准结果进行不确定度评定,为仪器测量结果可靠性提供前提保障。
Gasoline octane number is a digital index to measure the anti knock combustion ability of gasoline in the cylinder,which can be quickly measured by octane number tester.The accuracy and reliability of gasoline octane number measurement results can not only maximize the power and economic performance of gasoline,but also improve driving safety.This paper discusses the calibration of vehicle gasoline octane number tester based on dielectric constant method by vehicle gasoline octane number reference material,and evaluates the uncertainty of calibration results,so as to provide a prerequisite guarantee for the reliability of instrument measurement results.
