| Abstract: | This paper discussed a method to measure the engine speed by analyzing the engine cylinder vibration signal.By sampling the vibration signal produced by the burning gas in engine cylinder,then using the software of LabWindows/CVI to process the signal through frequency spectrum analysis and low-pass filter,combining the vibration source and the relationship between engine vibration and engine speed,we can get the speed of the engine.After experiment,this engine speed measurement system shows a high precisio... |
