DIESEL ENGINE CONDITION MONITORING TECHNIQUES

TECNICAS DE SEGUIMIENTO DEL ESTADO DE MOTORES DIESEL
PhD. Simón J. Fygueroa Salgado

Abstrac: Besides the known condition monitoring capacity as a highly reliable diesel engines predictive maintenance method its practical application in Colombia is already low due to the little knowledge about different apparatus and techniques used for thispurpose. Present work constitutes a short review about condition monitoring techniques used to diagnose diesel engines like non destructive, temperature, wear, vibrations and performance tests. Because engine operation level, size and load are very dissimilar this general study is made in order to provide the fundamentals to select the right technique for a specific application. Finally a group of conclusions are presented.

Resumen: A pesar de la reconocida capacidad que posee el seguimiento del estado (condition monitoring) como método altamente confiable para el mantenimiento predictivo de motores Diesel, su aplicación práctica en Colombia es todavía muy reducida, debido principalmente a falta de conocimiento de las diferentes aparatos y técnicas que se emplean con esta finalidad. En el presente trabajo se hace una somera revisión de las técnicas de seguimiento del estado que se pueden aplicar a los motores Diesel: No destructivas, temperatura, desgaste, vibraciones, y prestaciones. Se lleva a cabo un estudio general, debido a que los rangos de operación, tamaño y carga de los motores son muy distintos; de esta manera se tienen los fundamentos necesarios para seleccionar la técnica más adecuada para aplicar en una situación específica. Finalmente se presentan una serie de conclusiones.

Keywords: Predictive maintenance, diesel engines, condition monitoring, wear,performance.
