Abstract

In the maintenance of diesel engines wear parts and lubricant analysis are used to predict possible worst condition of equipments which may lead to premature failures Content of micro element in the crank case oil can be used to find the worst condition of the equipment Periodical lubricant analysis can reveal the microelements in the crank case oil Copper Iron Chromium Lead Aluminum and Silicon are the micro metallic particles normally come to the oil from wear and tear of engine Among these micro elements Silicon and Soot play vital role in wear and tear of the engine Four engines are used for this study Two brand new 12 Cylinder V-Type CATERPILLAR Engines of 5AG 2301 3412 DITA model coupled with 500 KVA power generator sets parallel operated engines based on power demand SAE 15W40 Unique oil CAT Fluid CI 4 has been used It was operated from 05 hrs to 1200 hour meter reading 80 variable load condition Another two sets of old 3406 C DITA 3306 B DITA Cat Engine with CAT DEO 15W40 oil has also been used for this analysis In this study how both silicon and soot materials accelerate the wear and tear is analyzed
