National standards for auto emissions testing because test equipment investment, the high cost of testing failed to spread. This paper presents a new test method and this method is developed based on vehicle- vehicle emissions testing system. Test system in the car to national standards under actual working conditions regulate road, a microcontroller real-time sampling exhaust pollutant parameters via serial communication transmitted to a PC , processed by the PC instantaneous emissions calculated using numerical integration way to get the whole process of total pollutant emissions from vehicles . Through experiment and analysis of the data , the test system has good stability.
