Abstract

Journal of Vibration and Control, Ahead of Print.
Valve clearance is critical for diesel engine reliability, where abnormal valve clearance faults (AVCF) severely compromise performance. Traditional vibration-based diagnosis methods predominantly rely on data-driven approaches, which suffer from ...
