The two experiments were done on stationary car at 800rpm, 1500rpm and running car on oscilloscope and chassis dynamometer at the speeds of 20km/h, 60km/h. In this experiment, the relativity between waveform, exhaust emissions and fuel consumption through two experimental methods were measured in case of cars with failures in MAP sensor, O sensor, spark plugs. The following results are obtained by analyzing the data relativity between two experimental methods, such as stationary and running tests. A simple stationary test under the maintenance of a decrepit gasoline vehicle would be realistic possibility to predict the fuel consumption and the exhaust emission comparable to results of running test with a chassis dynamometer.
