Study On The Impact Of Upgrading Of Vehicle Gasoline On Pollution Emission

On January 1,2019.Nationwide sales of national V-standard car gasoline are banned.According to a spokesperson for the National Standards Committee,the continuous upgrading of automotive gasoline improves the power of fuel and has a positive significance for environmental protection.In this study,46 national V vehicle gasoline samples and 172 national VIA vehicle gasoline samples were tested by various instruments and methods such as a mid-infrared gasoline and diesel detector.All samples were tested for benzene content,olefin content,and aromatic content,Oxygen content,sulfur content,distillation range,standard density,research octane number and other data.In addition,the average value of the above-mentioned indicators of automotive gasoline in two stages and the segmented data comparison of the measured values are analyzed to analyze what real changes have been made when automotive gasoline meets national standards,and what role it plays in the development of environmental protection.By comparison,after the automotive gasoline was upgraded,the measured average value and measured value segmentation of some indicators have changed.In general,92# car gasoline and 95# car gasoline are upgraded the rules are roughly the same.the vaporization temperature in the distillation range is reduced by 10%.The vapor resistance of the engine is too low.The temperature of the distillation point of each stage of automotive gasoline is more concentrated,which relieves the difference in the distillation point of different batches of gasoline The damage problem;the number of samples with 90% evaporation temperature in the high temperature range in the distillation range is greatly reduced,and the lower standard density of automobile gasoline in the stage VIA stage indicates that the incomplete combustion components and gums in automobile gasoline are reduced after the upgrade Problems;reduced the use of antiknock agents and reduced the pollution of manganese and other compounds;92# car gasoline and 95# car gasoline showed a halve in benzene content after upgrading,greatly reducing the direct volatilization of gasoline and The release of incompletely burned benzene is harmful to the human body.In general,the increase from the fifth stage gasoline to the sixth stage gasoline has important positive significance for reducing air pollution and protecting the ecological environment.
