The study of analysis technology of automotive exhaust

This topic is raised in the current that the vehicle exhaust pollution has been increasing higher and higher standards of automobile exhaust testing, with the aim of eliminating environmental interference and improves the accuracy of the exhaust gas. The system overcomes the shortcomings of the existing automobile exhaust gas analyzer, using the compensation method to judge the exhaust gas .the system uses different formula to calculate for the different parameters after obtained the data from the sensor, and will eventually provide a correct and accurate results when it compensated the signal affected by the environment by different methods.
