520			_aThe acoustic measurements of tractor engine valve train plays a crucial role in understanding the operational behavior and performance of these essential components. Valves and their associated systems are critical for the proper functioning of an engine, and any deviations from optimal conditions can result in reduced efficiency, increased fuel consumption, and potential engine damage. Therefore, accurate and reliable acoustic measurements provide valuable insights into the valve train dynamics and aid in identifying potential issues early on. This research aims to investigate the measurement of acoustic emission in an engine valve train using the Norsonic Acoustic Array 848a. The acoustic array is a powerful tool for capturing and visualizing sound sources, allowing for detailed analysis of the valve train performance. This study presents the methodology employed, including data collection, analysis, and interpretation. Calculations and observations are discussed, leading to valuable insights into the condition of the valve train components. The results contribute to a better understanding of the acoustic emission in engine valve trains and provide recommendations for maintenance and improvement. This abstract presents an overview of the acoustic measurements conducted on tractor engine valve trains. The primary objectives of such measurements are to analyze the sound characteristics generated during valve train operation, assess the performance of individual components, and detect any irregularities or abnormalities. To achieve these goals, various acoustic measurement techniques are employed, including sound pressure level (SPL) measurements, sound intensity analysis, and vibration measurements. SPL measurements involve capturing the sound emitted by the valve train during its operation using microphones strategically placed near the engine components. These measurements allow the determination of the sound power levels and frequency spectra associated with the valve train, providing valuable information about its operating conditions. Additionally, sound intensity analysis allows for the identification of specific sound sources and their spatial distribution within the valve train assembly.
