The analysis of the watered engine oil sludge

BACKGROUND: Researches in the field of engine oils sludging take its origin from 1955. Scientists different countries were searching for reasons, defining consequences, building a chain cause-effect links. Researchers have found that sludge represents complex compounds with low aggregative stability, such as: additives inserted into basis during production, partially oxidised fuel fractions subjected to thermal destruction, products thermo-oxidative transformations oil hydrocarbons. A number factors stimulate transient processes stability. One these is presence water. Water may penetrate through ambient air, service (washing), and as result condensation operation at temperature mode. Strengthening intermolecular interactions compounds, water initiates sludging.
 AIMS: Verification hypothesis about binding effect on composite package additives, content which determined by their indicator elements.
 MATERIALS AND METHODS: The experiment was carried out under laboratory conditions. Production watered intentionally order obtain sludge. Mixes made proportions. formed separated mixes further research.
 search elements-indicators analytical sample method raster electron microscopy. Japanese-manufactured labware represented Jeol JCM-5700 electronic microscope, JED-2300 Analys Station software package. microscope device intended acquisition object images, increased several thousand times huge spatial resolution, definition chemical elements compounds.
 RESULTS: conclusions are formulated visual investigations microscopy studies.
 CONCLUSIONS: practical importance lies integrity approach state change influence water, regarding transition dissolved firm (amorphous) state. Possible consequences watering blocking pickup screens filtering elements, unfairly active corrosion wear surfaces related details.
