A Review on Lubrication and Wear in IC Engine Using Acoustic Emission

The lubricant contamination against of engine component wear, leading to loss of engine performance and life, The dynamic lubricant oil films separating moving component surfaces cause a major portion of engine wear. The lubrication in the engine was successfully monitored based on the acoustic emission technique generated by captured using an AE wide band transducer that was bonded outside the engine block and located at the lower part of the bottom dead centre (BDC). The acoustic emission technique can assist the owner of the engine in determining the engine oil's condition before replacing it. In engine monitoring of the proper lubrication oil supply the cylinder is essential in achieving better efficiency for the engine in term of power, flue, and consumption. The AE analysis is an effective technique for on-line assessment of engine friction and wear, which provides to support the development of new engine fuels and new lubricants. The proper machine condition monitoring procedures. Need to attain high levels of asset availability, reliability and the cost of maintenance
