Designed to reduce friction, the timing chains deliver an improvement in fuel economy of as much as 0.3 to 0.6% based on customer testing, the company claims.
The all-new 8L90 was developed in house. GM claims it improves the Corvette’s powertrain efficiency by up to 5% versus the 6L80 and provides faster gear changes. It is over 8 lb (3.6 kg) lighter than the 6-speed while being equivalent in overall size.
Formula One rules for the 2014 season have changed in many areas, most notably the use of smaller-displacement turbocharged engines and a stronger hybrid-electric drive motor. Accompanying these changes are new gearbox specifications for 2014. The new rules call for eight forward speeds rather than the seven gears used in 2013.
The smaller total vent height (only 8.9 mm, or 0.35 in) provides more flexibility in component layout and facilitates heat transfer from printed circuit boards to the housing exterior.
The Palmer model PTG200 digital pressure gauge from Palmer Wahl Instrumentation Group is an excellent substitute for mechanical precision pointer pressure gauges.
Data Device Corp.’s MIL-STD-1553 XMC cards now include front and rear I/O options, along with air- and conduction-cooled configurations, to support a range of embedded applications.
High-contrast IR wire grid polarizers from Edmund Optics are suited for broadband infrared applications that require high transmission and contrast, including spectroscopy and thermal imaging.
The C530 general-purpose graphics processing unit from Aitech Defense Systems combines improved processing and high-data-throughput capabilities with a rugged design that is suitable for C4ISR and advanced signal processing.
A new SAE International book narrates the history of heavy-duty wheeled vehicles and presents the theory and calculations required to design them. Translated from Russian, the book summarizes the results of the authors’ academic research and experience, and presents innovative technical solutions used for electric and hydrostatic transmissions, steering systems, and active safety of these vehicles.
Concerns about airborne diseases and flu pandemics coupled with increasing passenger concerns about environmental conditions are prompting some aircraft designers to take a closer look at ventilation systems. In many instances, improvements in air quality and cleanliness are being expedited by using design tools such as computational fluid dynamics (CFD).
Deister Machine plans to launch its new BFO-11224-EX2 mine-duty screen at ConExpo-Con/Agg 2014. The 12- x 24-ft (3.7- x 7.3-m) horizontal, single-deck unit delivers reliability and high-volume capacities in a variety of hard rock mining and mineral processing applications, the company claims.
