Techniques for Improving the Efficiency of Agricultural Fluid Power Systems

1986-09-01
861299
Four alternative fluid power systems were analyzed to determine their efficiencies and standby power consumption while providing hydraulic power for power steering and a hitch for an agricultural tractor operating over a typical duty cycle. The investigation shows that a significant reduction in losses can be achieved with systems incorporating both split flow and variable delivery capabilities. These characteristics reduce losses by providing the required flow and pressure to each function without a large pressure drop for the function operating at the lower pressure. These systems can be used to improve efficiencies whenever there are multiple, simultaneous hydraulic power demands which require significantly different pressures.

Techniques to Upgrade Heavy Duty Aluminum Pistons

1986-02-01
860162
The demands on aluminum pistons from increasing diesel engine BMEP levels and longer expected service life are at the point that classical piston alloys processed with conventional casting techniques are no longer adequate. New processes and material enhancements are needed to upgrade heavy duty pistons. The application of the squeeze casting process to densify material improves the fatigue properties of aluminum alloys. This process also allows the use of fiber reinforcing to further improve the physical characteristics of squeeze cast diesel pistons. Metallurgical and physical test data on permanent mold, squeeze cast and squeeze cast metal matrix composite systems show significant differences in high temperature properties such as fatigue, tensile and thermal expansion. Wear characteristics are also compared. The property improvements observed will contribute to the continued use of aluminum pistons in heavy duty diesel engines.

Technology Breakthrough Achieves Objectives for SAE Preload Targets in Heavy Duty Wheel Ends

2009-10-06
2009-01-2887
Patents granted recently to Mr. Rode have changed the industry capability to adjust and verify wheel-end bearings on trucks. Until now it was believed1 that there was nothing available to confirm or verify the most desirable settings of preload on these bearings. The new, breakthrough invention is a tool and spindle-locking nut that permit quick and accurate wheel bearing adjustment by utilizing direct reading force measurement. Bearings can be set to either SAE recommended preloads or specific endplay settings. The author has been working on bearing adjustment methods for industrial applications for over forty years, and considers these inventions to be his most important breakthrough for solving this elusive bearing adjustment problem. Consistent wheel bearing preload adjustment was not possible before, even though it was widely known to achieve the best wheel performance as noted in SAE specification J2535 and re-affirmed in 2006 by the SAE Truck and Bus Wheel Subcommittee.

Paddy farming in India needs extensive water usage. Due to the rapidly declining ground water and ever increasing monsoon uncertainty, there is significant drive on water conservation for paddy farming through sustainable agriculture practices. The wide variability of irrigation water in Indian rice field, as high as 160 mm, necessitates an extra 100 mm of water in the field to provide complete water coverage. This is primarily due to inaccurate manual land leveling, often practiced in Indian paddy farming. In the present work, architecture of laser land leveler has been created by integrating low cost electronics, hydraulics and GPS technology. This paper will provide an overview of the current practices and suitable operating mode to meet the future demand on land leveling. The presentation would compare the laser land leveler with GPS land leveler solution architectures. The technological differences along with individual merits and limitations would be detailed.

Technology Exchange Between Universities and Industries

1996-04-01
961287
Technology transfer between universities and industries is discussed from two viewpoints: (1) the mechanisms of technology transfer and, (2) the future for university/industry interaction. The first major premise is that technology is transferred most efficiently through personal interaction; programs seeking to improve technology transfer should focus on promoting person-to-person contacts. The second major premise is that industry has become so dependent on a high technology that, as the Federal government reduces its support for academic research, industry will have to step in. This will require significant changes in attitude by all three parties: universities, industries, and the Federal funding agencies.

2023-01-0354
Commercial vehicles require fast aftertreatment heat-up to move the SCR catalyst into the most efficient temperature range to meet upcoming NOX regulations while minimizing CO2. The focus of this paper is to identify the technology levers when used independently and also together for the purpose of NOX and CO2 reduction toward achieving 2027 emissions levels while remaining CO2 neutral or better. A series of independent levers including cylinder deactivation, LO-SCR, electric aftertreatment heating and fuel burner technologies were explored. All fell short for meeting the 2027 CARB transient emission targets when used independently. However, the combinations of two of these levers were shown to approach the goal of transient emissions with one configuration meeting the requirement. Finally, the combination of three independent levers were shown to achieve 40% margin for meeting 2027 transient NOx emissions while remaining CO2 neutral.
