Research on Engine Fault Detection System Based on Exhaust Emission
Vehicle exhaust composition contains running state information of the vehicle. Real-time detecting emissions ingredients of the vehicle can realize engine fault diagnosis. Based on the engine exhaust emission abnormal reason analysis, the design scheme of the hardware and software of the system was established. By using the neural network and virtual instrument technology, the software of the engine fault detection system based on emissions was developed. This system is not only to test the gas concentration that contained in automobile exhaust such as CO, HC, CO2, NOx, O2 in different working condition, but also to diagnosis the working performance and working state of the engine.
