Yudina V. Technologies of zinc- barium containing dithiophosphate and motor oil for augmented diesel engines

Dissertation for scientific degree candidate of technical science on specialty 05.17.07 - chemical technology of fuels and lubricating materials. - National aviation university, Kiev, 2012. Dissertation devoted for zinc barium complex dithiophosphate additive development as main ingredient for augmented diesel engine oil. On a base of literature review necessity of new dithiophosphate additive development was shown. Process flow sheet, technological schedule proposed and pilot batch of MASMA-1606 additive produced. New additive package with MASMA-1606 proposed which provide necessary level of physical-chemical properties and performance attributes for augmented diesel engine oil. Positive results of laboratory, motor bench-top and motor tests allowed obtaining permission to produce and use AZMOL GARANT M-4042BT oil in two- and four stroke augmented diesel engines. Keywords: complex zinc barium containing dithiophosphate, motor oil, augmented diesel, tribological properties, formulation, functional properties.
