Interface Performance Materials has introduced two new thermal shields in the Select-a-Shield thermal product family—THH-1010 and TFP-3065—the first innovations in a series scheduled to be released through 2016.
A custom tractor-trailer technology demonstrator built by Alcoa is outfitted with various current and “soon-to-be-available” aluminum solutions that altogether can reduce the weight of a tractor-trailer by up to 2500 lb (1135 kg) compared to traditional steel components.
There is more pressure than ever on heavy-truck engineers to find and create significant improvements in fuel economy and reduce tailpipe greenhouse gas emissions. Aerodynamic opportunities exist with technologies such as active grille shutters and truck platooning—and simulation will help to optimize these designs.
An anchor product for T/CCI Manufacturing, the 7H wobble plate compressor is claimed to be the leading design in the industry for the heavy-duty truck and construction sector.
Many among the 13 partners that jointly developed the Genius CAB concept are firmly established in the automotive industry, and quite of few of these suppliers note the influence their automotive arms played in their contributions to the project.
Girish Parvate-Patil, works for Caterpillar Inc. as an Engineering Team Leader on marine propulsion systems. He is accountable for overall leadership and direction on engineering-related activities of marine products with respect to supply chain, design, documentation, time, and cost.
The challenges of climate change and energy security require a continuous effort toward reduction of global environmental pollution and fossil oil consumption. To meet greenhouse gas (GHG) emission targets and to decrease oil dependency, overall energy consumption of vehicles must be substantially reduced.
The four-year Clean High-Efficiency Diesel Engine (CHEDE) program is using a variety of new technologies and research findings to progress to a super-efficient, low-emitting heavy-duty diesel engine system with 55% brake thermal efficiency.
Exa and Navistar researchers examine CFD simulations and wind-tunnel test results to increase the understanding of simulation methods used to reveal aerodynamic losses in the real-world environment.
Active flow control devices based on electric plasmas can smooth the turbulent wakes that sweep off the rear edges of truck trailers travelling at highway speeds.
Off-highway machine mounting systems, especially the cab mounting system, significantly affect the operator comfort in the cab by providing enough damping for a good ride and isolating the structure-borne forces from traveling into the cab.
Researchers from Graz University of Technology consider the aerodynamic characteristics of general modifications to the outer contour of long-distance haulage trailers, including a new approach for the realization of a variable trailer rear end.
Researchers at Ashok Leyland make a case for choosing stainless steel over galvanized steel and aluminum for the complete bus structure. Although the initial material cost is higher for stainless steel, it scores better in other areas including mechanical and thermal properties and optimized structure weight. On the whole, the lower life cycle cost (LCC) offsets the initial material cost and yields rich dividends to the end customer, they claim.
As part of the U.S. DOE SuperTruck program that was awarded to Cummins and Peterbilt Motors, a series of investigations was conducted on the aerodynamic ramifications of traffic. One such investigation, carried out by experts from Peterbilt and design software provider Exa Corp., focuses on the impact of traffic conditions on aerodynamic drag for typical tractor-trailer separation distances at typical highway speeds.
