“Walking on Automotive Waste? - Plastic Recycling Opportunities for Waste Automotive Materials in the Footwear Industry Sector”

1998-02-23
981162
This paper demonstrates the possibilities of using Automotive waste plastic material from “end of life” vehicles (ELVs), in the Footwear Industry to manufacture shoe components. The study establishes the sustainability of the flow of ELVs, from the European Car Parc and identifies and estimates the quantity of plastic materials potentially available for recycling from ELVs. Four potential materials, Acrylonitrile/butadiene/styrene (ABS), Polypropylene (PP), Polypropylene/ethylene/propylene/diene (PP/EPDM) and Polyamide (PA), were identified and three materials (PP, PP/EPDM and ABS) were reprocessed from ELV components and evaluated by the Footwear Industry. As a result, ABS was recommended as an economically, suitable replacement for HIPS, the current material used for manufacturing shoe heel components.

“U” Bolt Torque Influence over Leaf Springs

2014-05-07
2014-36-0024
”U” bolts are fixing elements and they are used to clamp an elastic joint. From the past, they still looking as an old design and unfortunately, suspension engineers are not specialists in fasteners and elastic joints. That is why we will show important assumptions and concepts to design and specifications this clamp element “U” bolt and its influence over leaf-springs. Currently, “U” bolt is used to clamp an elastic or elastic-plastic joint of heavy duty suspension, formed by leaf-spring, axle, spring pad, “U” bolt plate. This kind of suspension is typically used to trucks, buses and trailers. We are wondering, which one important assumption that an engineer must be careful when designs a new suspension changing from old designs to an updated technology. We provide a theoretical analysis and a FEA analysis to compare torque efficacy x leaf-spring reactions and what are effects this relationship can cause in a suspension.

“Triple-Safe” Air Brake System: Service, Emergency, Parking

1971-02-01
710211
The term triple safe is used to identify an air brake system with three separate circuits, two of which are service brake systems of virtually equal effectiveness; the third is a spring parking brake system. The paper reviews the spring parking brake chamber capability and describes a triple-safe air brake system and chambers that have similar service and emergency capacities, and parking capabilities, to meet future requirements of trucks and buses.

“The Creation, Development and Implementation of a Lean Systems Course at Oakland University, Rochester, MI”

2005-04-11
2005-01-1798
Countless articles and publications3,4,5 have documented and proven the efficacy, benefits and value of operating within a lean system. Furthermore, there exists common agreement amongst leading organizations successfully implementing a lean system that in order to do so it must take into consideration the entire enterprise, that is, from supplier to customer and everything in between6. One of the core issues this paper addresses is when the optimal time is to train and educate the people who currently have, or will have, influence over the ‘enterprise’.

“TFC/IW in 1982”

1982-02-01
820301
TFC/IW, total fuel consumption divided by inertia weight is reported with other engineering variables for recent EPA data for industry passenger cars and truck. TFC/IW is used in comparisons between gasoline and diesel engines, 49 States and California, passenger cars and trucks. The California fuel economy penalty due to more stringent emissions standards is discussed. The relationship between TFC/IW and ton miles per gallon is shown. Special attention is focused on 4 cylinder gasoline powered vehicles in 49 States passenger car fleet. The use of TFC/IW to answer the question, ‘What Changed?’ when comparing the fuel economies of two fleets is described.

“Spacematic” Monitoring System

1998-09-15
982138
Pneumatic, manually operated, drilling machines are used to produce a significant proportion of all holes drilled during wing manufacture. Drilling machine design and the manual drilling process has not changed significantly in decades. By employing miniature, low power, electronics and interfacing techniques, a monitoring system has been developed. This system enables improved process control of the manual drilling operation. Machine calibration management, measurement of drill performance, jig drilling error control and asset management are some of the benefits attainable. This project will hopefully encourage others to discover the potential for improving historically established processes, by employing modern technological developments.

“STATE OF THE ART” REPORT ON WINTERIZATION OF CONSTRUCTION EQUIPMENT

1964-01-01
640064
As increasing populations set demands for the abundant natural resources of the colder regions, the complex industrial machines of American Industry are expected to build the new railroads, roads, cities, mines, power sources, airports and factories, and operate these activities year round. This paper reviews the basic problems of “winterization” and the design practices, materials and components used with varying effectiveness in “winterizing” construction and associated equipment for use in moderate and extreme cold geographical areas. Several new charts are included which offer design temperature data for the northern United States, Canada, Alaska, Greenland, as well as average January isotherms around the earth. The authors are members of CIMTC Subcommittee XV, “Environment”.

“SHIFT-MATE” A Fuel Efficiency Monitor

1985-12-01
852340
The SHIFT-MATE is a dashboard mounted computer based device that cues a truck driver to shift more efficiently. Through electronic circuitry, key vehicle parameters are monitored, computed, then via graphic display, instructs the driver when to shift for improved fuel economy. The theory of operation is described in the text.

“Return to Nascar” Dodge NCTS History

2002-12-02
2002-01-3353
Dodge wanted to promote the new Dodge Ram 1500 pick-up truck and regain a presence in NASCAR and was looking for a venue that would accommodate this presence. NASCAR launched the NASCAR Craftsman Truck Series (NCTS) in 1995 and Dodge joined the series. This paper will cover the history of Dodge Motorsports Engineering presence in this series. The engineering objective was to develop an organization that would meet the corporate goals. The initial problem was that Dodge hadn't participated in a NASCAR series since 1978 and had no recent experience. The conclusion was that Dodge Motorsports Engineering could be competitive in NASCAR series racing.

“Remanufacturing”: The Sustainable Service Solution for Past Model Automotive Electronics Support

2008-10-20
2008-21-0029
In this paper, remanufacturing will be explored as a feasible option to maintaining the serviceability of electronic modules fitted to vehicles entering their service life from year four (after warranty) and beyond. Understanding the makeup of each module (content, design, and complexity) determines the feasibility of remanufacturing along with its cost effectiveness. Problems exist storing components for many years and engaging in periodic manufacturing is not cost competitive for high content modules. Thus, if reverse capability is not an option, then remanufacturing is a viable solution that, for certain modules, is a cost effective and an environmentally responsible (sustainable) solution to the service parts dilemma.

“Real-Time Estimation of Soot for a Wall Flow DPF Regeneration Management and an Efficient DOE for Model Calibration.”

2021-09-22
2021-26-0333
Estimation of soot deposited on a wall flow type DPF, is a vital information to ensure safe and efficient DPF management. Accuracy in determining mass of soot present inside the DPF ensures a correct regeneration management strategy in-terms of fuel efficiency and DPF safety considering soot overloading and too frequent regenerations. It also ensures an efficient detection of anomalies in the PM filtration mandated by the BSVI/EURO VI legislation as a part of On-board diagnostics. Classical approach of determining soot present inside DPF involves monitoring increase in pressure drop. Real time usage of such a model is limited by the inaccuracy of measuring pressure drop at low exhaust flows. Hence, contemporary engine controllers use pressure drop based models as a failsafe and estimate DPF soot loading by modelling soot release rate due to engine combustion and the rate at which it is oxidized.
