Title: Andrew G Horodysky: Innovator in Lubricating Oil Technology

Introduction:

Meet Andrew G Horodysky, an esteemed inventor in the field of lubricating oil technology. With a location in Cherry Hill, NJ (US), Horodysky has made significant contributions to the industry with his numerous patents and innovative ideas. This article explores his latest patents, highlights his career achievements, and sheds light on his collaborations with esteemed colleagues in the field.

Latest Patents:

One of Horodysky's recent patents, "Method for reducing one or more of deposits and friction of a lubricating oil," presents a groundbreaking technique for improving deposit control and reducing friction in engine lubrication. This method involves utilizing a specific additive combination that includes a borated hydroxyl saturated hydrocarbyl ester amide-amine mixture, zinc dialkyl dithiophosphate, and a metal salicylate detergent. Compared to traditional lubricating oils, this method displays enhanced deposit formation control and reduced friction.

Another noteworthy invention is his patent on "Lubricant air release rates," where Horodysky devised a composition that significantly enhances the air release rate of lubricating compositions. By incorporating vinyl aromatic-olefin block copolymers that form a micelle-like structure in the oil, the composition retains less than about 2.5% air after 1 minute at 50°C, as tested by ASTM D 3427.
