Contact the SAE Learning Center at http://mylearn.sae.org to register for the class.

Learning objectives

By attending this seminar, you will be able to:

  • Describe the function of each ring and its interaction with other components within the cylinder kit to provide oil consumption and blow-by control
  • Identify available computer models and instrumentation that is available to predict and measure the function of each of the components in the cylinder kit on oil consumption and blow-by control
  • Compare the base systems and facing material systems and the trade-offs associated with each of the material systems, i.e., wear rate, scuff resistance, etc.

Who should attend

If you are an engineer associated with engine design and development and interested in understanding the function and design considerations within the cylinder kit system, you would benefit from attending.

Prerequisites

Participants should have an undergraduate engineering degree and some exposure to piston ring design and materials.

Topical Outline

  • Background
    • Evolution of piston ring designs/materials -- diesel engines
    • Evolution of piston ring designs/materials -- gasoline engines
  • Outline of nomenclature and ring design methodology, including referencing to various published standards i.e. -- SAE, DIN, ISO
  • Systems parameters and their interaction with piston rings to cause variations in performance
    • Cylinder bore geometry
    • Cylinder bore finish
    • Piston design
    • Power density
    • Operating speed
    • Engine Lubricants
  • Typical procedures and equipment employed to measure dimension properties of piston rings
  • Developed models aiding cylinder kit design
  • Determining the effect of design parameters on oil consumption, ring function, cylinder bore distortion, friction and wear rates -- unique test set-up procedures and their utilization

Instructor:  Harold McCormick

Harold McCormick is currently President of C-Engineering, Inc., an engineering firm specializing in providing analysis instrumentation gauging and other consulting services for engine and lubricant manufacturers.  He was formerly Director of Engineering, Ramsey Plant TRW-Valve Division, with ongoing responsibililty for research and product engineering.  He has also completed 57 graduate hours in Applied Mechanics and Metallurgy at St. Louis University. His experience has involved directing substantial work to develop models/test procedures and test fixtures that can be to predict wear in severe wear applications such as piston rings, engine exhaust and valve seats as well as severe dry sliding wear applications.  He holds more than 40 U.S. patents and has authored or co-authored numerous technical papers for the SAE International as well as other automotive engineering organizations.  Mr. McCormick holds a B.S. in Mechanical Engineering from University of Missouri - Rolla and a M.B.A from St. Louis University.
