This paper will demonstrate the benefits of a small-team approach to the design of a high-profile, special-purpose vehicle intended to showcase the technology and abilities of a complete supplier network. Using traditional and latest technology methodologies, the project will be delivered on time and within budget to the complete satisfaction to all participants. The paper provides a brief review and history of the industry within the context of the topic and then gives a background to the aXcess Australia concept as it was applied to the Low Emission Vehicle. There is a confirmation that a mixture of techniques, both traditional and modern, can coexist and in fact provide better outcomes within a restricted budget and timeframe.

Boosted Engine Systems components are those that supply and control the combustion air to the engine. The Boosted Engine Systems strategy is to optimize the air supply system to provide best efficiency for the actual intended duty cycle. This process involves measuring and analyzing the engine/vehicle duty cycle, and then optimizing the design of the system for best efficiency during that mode of operation. This approach can improve fuel efficiency, reduce emissions, reduce system weight and cost, and reduce the number of components in the system. Suggestions are made for optimum component design to meet system needs.

Engine Cooling and Air Conditioning tests were performed using a sports utility vehicle with a V-6 engine. The original vehicle was equipped with an engine driven fan. This vehicle was modified by adding electric motor driven fans, air path sealing and advanced heat exchangers in a predetermined test configuration. Engine cooling performance and air conditioning performance were evaluated at each step. Identical grade load and idle tests were conducted with this vehicle at each step. The V-6 sports utility vehicle was selected due to its use of an engine driven fan. The grade load of 8.7% was selected due to off road use by the consumers. The results of the testing showed that engine cooling performance and air conditioning performance were improved by using electric motor driven fans, air path sealing and advanced heat exchangers.

AN INTERDISCIPLINARY TEAM from Purdue University is developing a comprehensive set of educational materials for agricultural safety and health for OSHA, of the U. S. Department of Labor. The team from the Purdue school of Agriculture, school of Veterinary Medicine, and the school of Humanities, Social Science and Education are working for a year and a half to gather and catalog all existing safety materials, and to produce new ones to meet nationwide needs. The project was begun on July 1, 1974 and is scheduled to be completed by December 31, 1975. The project team includes John B. Liljedahl, professor of agricultural engineering, project leader; Avery H. Gray, assistant department head, 4-H and Youth; William H. Hamilton, agricultural education; David H. Loewer, Extension agricultural engineer; David L. Matthew, Extension Entomologist; Vernon B. Mayrose, Extension animal scientist; Ken Weinland, Extension veterinarian; Bruce A. McKenzie, Extension agricultural engineer; James L.

DATA from several fatigue-test programs are examined in this paper for corroboration of basic factors which have been proposed for predicting more accurately the fatigue strength of full-scale steel members. Important among these factors are hardness, service loading, range of stress, and sharpness of the stress gradient at the critical zone. Although the type of steel is often regarded as a primary factor, its hardness may be more basic, as it correlates better with endurance limit than other physical tests. Test results show that this hardness-strength relationship is useful in evaluating the effect of surface treatments on strength improvement in soft and medium-hardness steels.
