Modern Fluids for Internal Combustion Engines: An Overview 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
    • corrosion
    • piston cleanliness
    • swelling of seals
    • hydraulic media in fuel systems, such as hydraulically-actuated electronically-controlled unit injector system (HEUI).
  • Recognize the limitations and technical trends in new base stocks and additive technologies
  • Compare performance characteristics of lubricants designed for passenger cars manufactured in N. America, Europe or Japan
  • Identify key lubricant requirements for protecting heavy duty diesel engines
  • Select and optimize fluids for various light duty and heavy duty after-treatment applications
  • Recognize differences between API, ACEA, and ILSAC lubricant categories

Who Should Attend
This seminar is designed for engineers, scientists, investigators and consultants involved in designing or optimizing mobile or stationary powertrains. Individuals interested in understanding the role of crankcase fluids in extending useful life of the overall systems, minimizing emissions and reducing fuel consumption will find the seminar beneficial.

Attendees should have a background in science or technology and some technical familiarity with performance of engines and emissions. No previous exposure to organic chemistry is required.
