Pollutants Analysis And Control Exhaust Emissions From Gasoline Vehicles

It shows that the automobile emission is one of the main sources for the air pollution. It is much more than those generated by any other single human activity. We should pay attention to the automobile itself to control and manage the emission. Besides developing more advanced control technology in the design&manufacturing, building more burning working environment, innovating more purification technology, we should focus more on the emission control about running automobile on the road. In the car of gasoline vehicle emission pollutants amount is huge,is the main source of,so in the use of gasoline motor car exhaust pollutant is a problem to be solves,is the key to protect environment.The subject comes from life.With the help of vehicle environmental testing station practice and typical gasoline vehicle4S shop maintenance practices, The theoretical bases are the generation principle of gasoline car emission and electrical principle of motor. The analyzed target is the unqualified gasoline cars tested by Nanjing Environmental Protection Testing Station.This paper foused on the gasoling vehicle exhaust emission pollutants exceed the standard reason and control method of analyzing problems,mainly in the following research work:1.In the analysisi of the gasoline veicle exhaust emission pollutants harm,formationg mechanism and the common contro methods.Through the analysisi ofporeign advanced in the use of gasoline motor car exhaust emissions testing standards and testing meithods,combine our country national condition analysisi our country existing in gasoline vehicle standaids and detection meithods,find out our country and developed country the difference between.2.Through research,analysis of Nanjing city environmental protection monitoring station at the preseng stage of the gasoline car environmental testing performed by the testing standards,equipment requirements,detection method and detectiong process.3.Analysis of Nanjing city in the gasoline vehicle environmental protectiong detects unqualified situation,study the cause of these vehicles unqualified reasons,and by means of addressing these exceed the standard problem of vehicle repair.After a variety of pollutants exceed the standard,various reasons and control metheods are summarized.Finally the control examples for in use gasoline vehicle exhaust emission pollutants exceed the standard solutions and measures,achieved lower in use gasoline vehicle exhaust emission anount,to achieve environmental testing requirements.I hope it can give some help to those gasoline car owners and companies.
