Diagnostic of Localized Engine Faults Using Vibration Monitoring 2009-01-1610

Despite considerable advances in predictive maintenance concepts are still largely reserved for only the most critical system components and have not found their place in mainstream machinery health management. Even though there are a number of condition monitoring and analysis techniques, researchers are in search of a simple and easy way to monitoring the condition of an engine, which is an omnipresent and an important power unit in any vehicle or machinery. Vibrations have been the most recent easy to measure condition monitoring. However, this paper will provide the details of diagnostic technologies that can be applied on a single cylinder diesel engine components, and span a continuum of sophistication and rely upon the availability vibration measurement equipments. The vibration measurements are used as monitoring parameters, while single-processing indices are used for diagnosis procedure. Furthermore, the results serve as a motivation to encourage further research in those challenges areas of data collection and management, validation and verification, implementation and assessment that are critical to a successful penetration of these technologies in the industrial and manufacturing sectors of our economy.
Intervals, is often guided by sub-contractors or operation experience. With the technique one tries to prevent components, sub-systems or systems to degrade to the degree of breakdown. This is done by reparations, service or component exchange in present intervals.
