Modern Fluids for Internal Combustion Engines: An Overview 2 Days | Classroom Seminar I.D.# C0704 Lubricating fluids are the lifeblood of modern engines, performing numerous vital functions from reducing system friction, temperature, and fuel consumption to minimizing tailpipe emissions. This comprehensive seminar covers the latest developments in lubricating fluids technologies and explores the relationships between lubricating fluids and emissions, after- treatment devices, bio-fuels, and fuel economy. Fundamentals of crankcase lubrication, including the properties and performance requirements of global base stocks and lubricants will be covered. The seminar will further explore the need for lubricating systems to possess thermal and oxidative stability sufficient to withstand the rigors of low-heat-rejection, high performance diesel engines or other modern engines equipped with various emission control devices. Case studies will be utilized to demonstrate the existence of overlapping phenomena aimed at extending oil life and protecting key mechanical components. Learning Objectives By attending this seminar, you will be able to: • Describe how various classes of additives commonly used in crankcase lubricants impact: −− wear of bearings, pistons, and piston rings −− friction and fuel consumption
