“…Tribometer can apply up to 60 N normal load to the samples at 0‐ to 50‐mm stroke length, record friction forces up to 60 N with a ± 0.1 N resolution between 1‐ and 10‐Hz frequency. In this work, 25 N normal load, 0.1‐m/s sliding speed with 5‐mm stroke, and 400‐m total sliding distance were chosen to achieve contact pressure of the cam tappet/valve train system, and also boundary lubrication condition . About 0.5 cc lubricating oil (approximately 1 drop) was dropped on the steel surface, and samples were heated to 100°C, and then tests were started.…”

“…Boric acid (H 3 BO 3 ) was synthesized from commercial Borax (Na 2 B 4 O 7 .10H 2 ) powder with the following chemical reaction: and 400-m total sliding distance were chosen to achieve contact pressure of the cam tappet/valve train system, and also boundary lubrication condition. 27 About 0.5 cc lubricating oil (approximately 1 drop) was dropped on the steel surface, and samples were heated to 100°C, and then tests were started. To provide stable temperature during the tests, heating was controlled by thermocouple-proportional-integral-derivative of the heating module (see Figure 2A).…”

Zinc dithiophosphate (ZDDP)‐free environmental friendly lubricating oil research studies have gained importance due to the governmental regulations over the last decade. In this study, low concentration boric acid‐base oil and ZDDP‐base oil mixtures were investigated with a ball on flat reciprocating tribometer to evaluate their tribological performances. The tribological performances of 1, 3, and 5% additive and base oil mixtures were evaluated at boundary lubrication condition in three main contexts including wear rates, surface tribochemistry, and friction. Results showed that there was no significant difference between boric acid and ZDDP friction coefficients. However, boric acid showed poor wear resistance when compared with ZDDP and it cannot be an alternative additive alone to ZDDPs.

“…Most of the energy produced by the explosion of the air-fuel mixture is converted into heat, which has to be extracted through the walls of the chambers to the proper block and to the refrigerating fluids. Heat extraction has to be efficient otherwise the engine block may be subjected to excessive thermal loads that will modify the mechanical properties of the alloy from which the block is made, leading to its catastrophic failure [1,2]. Engine blocks in automobiles have been migrating from cast iron to aluminium alloys [3,4] to reduce their weight, improve fuel consumption and comply with environmental regulations imposed by governments in different countries.…”

“…Engine blocks in automobiles have been migrating from cast iron to aluminium alloys [3,4] to reduce their weight, improve fuel consumption and comply with environmental regulations imposed by governments in different countries. Unfortunately, conventional aluminium alloys do not exhibit the resisting capabilities required for sustaining the wear caused by the reciprocating movement of the pistons, so most engine blocks are manufactured with sleeves or liners made from wear resistant alloys, which will result in the increase of around 6 kg in a V8 engine when grey iron liners are used [2,5].…”

is director of the Master of Engineering in Engine Systems program at the University of Wisconsin Madison. She worked in the aerospace industry designing jet aircraft engines before joining Ford Motor Company. At Ford, she trained power-train designers and engineers in CAD and CAE and produced web-based trainings on topics such as reliability and experimentaldesign. She also worked in the Office of the Technical Fellow, exploring new technologies to automate the product development process and shorten product development time. Anderson received her PhD from the University of Oklahoma in aerospace engineering. She also has an MBA degree from the University of Dallas and is a six-sigma black belt. Using On-Line Education to Meet the Needs of Working Engineering ProfessionalsWorking engineering professionals and their employers understand the value of, and the need for continuing education; be it training courses, certificate programs, or advanced degrees. These consumers are looking for an efficient means to gain the required skills and knowledge to move their career, company, or project forward. These consumers demand well-written and wellpresented material that matches their current need for knowledge. Often, the best approach to meeting these needs is a team consisting of university faculty members, highly respected industry professionals, and individuals trained in instructional design. The purpose of this paper is to show the method that was used to develop a successful on-line education program. Introduction-For most engineers it is a tough decision whether to continue on for a Master's degree after graduating with a B.S., and for many because of family and financial responsibilities there is no choice but to take a full time position in industry. These working engineers see an increasing need for education beyond a B.S. but cannot afford to leave their jobs, move their families and attend university full time.A distance degree program where the students can work on their degree part time while working, traveling, and holding family responsibilities fills the need of many working professional engineers. Group projects, live web-conferences, threaded discussions, and yearly one-week residencies provide students networking opportunities, and give the benefit of increased student interactions.This paper outlines the method used to develop and implement the Master of Engineering degree, Engine Systems (MEES) program, a successful on-line degree program at the University of Wisconsin Madison.Background-
