Improvement on Determination of Lead in Unleaded Gasoline by MIBK-Glacial Acetic Acid System;

A study on Burden of disease since the Application Unleaded gasoline in Shanghai;

ObjectiveTo explore the health effect of air pollution frommotor vehicle emission on school pupils after introduction of unleaded gasoline.

Study on exhaust valve seat for lead-free gasoline 462Q engines;

The forecasted and tested plumbum contents in TSP of the ambient air of the main traffic line after using lead-free gasoline show that after using lead-free gasoline, there is a great decline of plumbum content in TSP of the ambient air and a difference between the two results.

After making comparisons through experimentation,it is proven that the material has excellent high temperature strength,high wear resistance,good corrosion resistance and thus is suitable for use in lead-free gasoline engine.

This paper analyzed new emission standard for vehicles, technological innovation for enterprises and relevent policies and elaborated feasibility of which noncontaining lead gasoline policy is being carried out in our country.

It is discovered that when Pb-poor gasoline is replaced by naphtha or iso-octane as a reagent blank,background absorption will be lower and that the determining result will be higher in regard to positive deviation.
