General Calculation on Measuring of Engine Exhaust Emission

Exhaust emission from engines is significant source to pollute air.In order to control and reduce engine exhaust emission,it is necessary to get an appropriate tool to measure emission.The article discussed some relative researches with the purpose of popularizing the engine emission measure tool,which include the comparison of hardware equipments and test tolerances.Based on the contrast experimentation,it also studied the relativity of different results from different emission tester.All research results are integrated into a software tool as reference for engineers.
