Automotive Engine and Hardware Overview

OverviewThis presentation will cover basic engine components, critical tribological contacts and the frictional losses at these contacts.  An overview of materials used for these components will be provided.  The basic concepts of boundary, mixed and hydrodynamic lubrication regimes and their relationship to minimum oil film thickness will be provided, along with strategies for reducing friction in these interfaces.

Instructor: Dr. Edward P. Becker, Friction & Wear Solutions, LLC

Biography: Ed Becker is a Past President and Fellow of STLE.  He holds a Ph.D. in Mechanical Engineering from the University of Michigan and retired from General Motors after 30 years of service, mostly in the Powertrain division working on a variety of GM engines and transmissions.  Ed then established Friction & Wear Solutions, LLC, which provides advice on materials to solve tribological problems.  He is a licensed Professional Engineer in Michigan.

Automatic Transmission and Vehicle Drivetrain Overview

Overview: Automatic Transmission Fluids provide a variety of functions in modern automobiles, including torque transfer, cooling, hydraulic power, and component proteciton.  The basic componets of ATFs will be discussed, including base oils and additive packages, to meet differing OEM requirements.  Recent work related to the development of a “universal” ATF for service fill will be presented.

Instructor: Dr. Chintan Ved, Ford Motor Company

Biography: Chintan Ved has been with the Ford Motor Company in Dearborn, Michigan for over 14 years, most recently serving as a Technical Expert - Powertrain Lubricants.  He holds an MPD in Product Development from the University of Detroit—Mercy, an MS in Chemical Engineering from Cleveland State University and BS, Chemical Engineering from the University of Pune, India.  He is a member of SAE, AIChe and STLE.

Engine Oils and Transmission Fluids

Overview: Modern engine oils are highly engineered fluids critical for the proper performance and protection of internal combustion engines.  This class will provide an overview of the engineering of modern engine oil formulations, highlighting the different base oils and additives used, and the engine oil development process. This class will also highlight the importance of using engine oils that meet the viscosity grade and specification required by the engine manufacturer.

Engine and Vehicle Bearings

Overview: An overview of the types of bearings used in motor vehicles, and the tribological challenges and solutions for each.

Instructor: Dr. Ryan D. Evans, The Timken Company

Biography: Ryan D. Evans is currently the Manager of Engineering Fundamentals at the Timken Company.  He has been with Timken for more than 10 years, holding various positions in Timken’s R&D organization and making technical contributions in the areas of surface engineering, thin film coatings, lubrication, tribology testing, and wear.  He has a Ph.D. in Chemical Engineering from Case Western Reserve University.  Ryan has been an active volunteer for STLE, serving on the Surface Engineering and Rolling Element Bearings Technical Committees, the Awards Committee, and currently he is a member of the Annual Meeting Program Committee (AMPC).  He was the recipient of the STLE Walter Hodson Award in 2007 and the Surface Engineering Technical Committee Best Paper Award in 2009.

Piston and Piston Ring Friction and Lubrication

Overview: The piston ring is one of the most tribologically intensive and functionally important parts of the reciprocating engines and compressors. Piston rings account for 50-60 % of friction loss between the piston and bore. The three main functions of piston rings in reciprocating engines/compressors are: Sealing the working chamber from the crankcase; Supporting heat transfer from the piston to the cylinder wall, and Regulating oil consumption. Piston rings are also being used increasingly as seals for rotating shafts in some rotary compressors and transmissions, for example. There are a number of system parameters that affect performance of the piston rings. These include piston design, cylinder bore geometry, lubricants, and cylinder bore finish, operating speed, rings design and other.
The purpose of the seminar is to focus predominantly on the issue of conformability of the piston rings, which is defined by rings’ design and cylinder bore distortions. The conformability is one of the major mechanisms affecting piston rings’ performance.

Instructor: Dr. Val Dunaevsky, VVD Engineering

Biography: Dr. Valery (“Val”) Dunaevsky is a recognized expert in surface metrology, tribology and contact mechanics. He is the acclaimed author of many technical papers and patents. He is a leading face in the field of piston rings mechanics. Dr. Dunaevsky is the author of the 2D conformability analysis of piston rings that has been utilized by many motor builders. He was the first one who understood the necessity of a 3D conformability analysis. Piston rings conformability is one of the major factors affecting oil consumption and cylinder kit efficiency. Under Dunaevsky leadership the advanced conformability methodology is being developed. 

Surface Texture Measurement/Analysis for Automotive Applications

Overview: Friction , wear, fluid leakage, adhesion, appearance and other phenomena may be affected by the surface texture comprising critical components.  This class will include material on instrument setup including spatial filtering selection (i.e. cutoffs), 2D parameter (e.g. Ra) and the newer 3D parameter selection (e.g. Sa). Characteristics of surface texture as related to friction, wear, sealing and NVH will be presented.

Instructor: Dr. Donald K. Cohen, Michigan Metrology, LLC

Biography: Dr. Cohen has undergraduate and graduate degrees in Physics and Optical Sciences from the University of Michigan-Dearborn and the University of Arizona respectively. Early in his career, Dr. Cohen worked with IBM on optical disk drive development. He later joined WYKO Corporation as product manager and eventually Vice President, developing 3D surface texture metrology instrumentation. In 1994, Dr. Cohen established Michigan Metrology to help engineers and scientists solve problems related to leaks, squeaks, friction, wear, appearance, adhesion and other issues, using 3D MicroTexture measurement and analysis.  Dr. Cohen has been Chairman of the STLE-Detroit section and has been active with the ASME B46.1 national committee on surface texture since 1988 where he currently serves as Chairman.

The Future of Automotive Propulsion

Overview: The worldwide demand for automotive transportation remains strong even as the price of conventional fuels fluctuates.  The General Motors Company is committed to providing safe and affordable vehicles which run on whatever fuel is available in a particular market.  To assist in extending the current supply of fossil fuels, automakers (including GM) are expanding the use of fuel-saving technologies such as variable valve actuation, cylinder deactivation, additional forward-speed transmissions, and hybrid powertrains.  In addition, vehicles which run on Compressed Natural Gas (CNG) and alcohol-gasoline blends (such as E85) are commercially available.  GM has also demonstrated a hydrogen fueled, internal combustion engine vehicle and is aggressively pursuing fuel cells for automotive transportation in the future.
