This study explains the properties of lubrication oils unused & after
use. The total number of samples used in this study were 14 samples 8
oils (gasoline ) and 6oils (diesel ) were conducted by specialized work-
shops with certain devices . The samples were taken directly from engines
and followed by regular registration for kilometers. These samples were
tested before and after the use to define certain physicochemical properties,
viscosity, density, basicity and acidity, color, ash content and anti-oxidant,
erosion properties. The concentration of certain metals (Fe-Pb-Ni-Cu) in the
oil was also determined using standard atomic absorption spectra
photometer method. However in concentration of metals (Ca-Mg-Zn-P)
were measured by X—ray fluoresces method. . The study covers the effect
of environment and climate on engine the study shows the mixing of oil with
oxidation and corrosion, erosion and dust all, leads to change in the
properties of oil either decrease or increase the property under discussion.
Found that there was a decrease in the total base number in the used oils due
to presence oh the acids resulting from oxidation .There were a decrease in
additives due to consumption. Some oils show increase in viscosity and this
may be due to contamination by solid materials. There was an increase in
concentration of iron, lead, copper, and this may be due to friction and rust. |
