Summary, etc. This study presents the use of acoustic emission (AE) analysis in combination with signal<br/>processing and LabVIEW software for monitoring 4 different types of oils in different conditions.<br/>AE signals were collected using a free filed microphone 4188 with good frequency range placed<br/>near the valve train, and the signals were conditioned using a signal conditioner to amplify the<br/>signal. The amplified signals were then processed using Fast Fourier Transform (FFT) analysis<br/>with National Instruments DAQ cards and LabVIEW software to extract features related to valve<br/>train behavior i.e. engine sound, frictional torque etc. The results showed that AE analysis using<br/>LabVIEW and signal processing techniques can effectively detect and characterize valve train<br/>behavior under various operating conditions. Then investigates the effect of different engine oils<br/>on the behavior of engine valve trains using acoustic emission (AE) analysis and FFT analysis<br/>with LabVIEW software. Four different types of engine oils of the same grades were tested on a<br/>single-cylinder four-stroke engine with four valves. AE signals were collected using a microphone<br/>and amplified using a signal conditioner, and then analyzed using FFT analysis with National<br/>Instruments DAQ cards and LabVIEW software to extract peak values related to valve train<br/>behavior. The results show that the different types of engine oils have a significant effect on the<br/>peak values of the AE signals, which is indicative of valve train behavior and from this behavior<br/>the frictional torque can be find out[1]. The study demonstrates the potential of AE analysis and<br/>FFT analysis with LabVIEW software as a valuable tool for evaluating the performance of engine<br/>oils on engine valve train behavior.<br/>
