Abstract :
The lubricant contamination of diesel engines component wear, leading to loss of engine performance and
life. Lubricant analyses are used to predict possible worst condition of equipment, which may lead to premature
failures. The content of microelement in the crank case oil can be used to find the damaged 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 the
engine. Among these microelements Silicon and Soot play a 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. Another two sets of old 3406 C DITA and 3306 B DITA Cat Engine
with CAT DEO 15W40 oil has also been used for this analysis. In this study, the behavior of both silicon and soot
materials for the increased wear and tear are analyzed. Experimental results revealed that, controlling both Silicon
and Soot will improve the life of other components of the engine in an appreciable level.
