Heavy-duty designs on aftertreatment The introduction of stringent EPA 2015 regulations for locomotive/marine engines and IMO 2016 Tier III marine engines precipitated the need to develop large diesel engine aftertreatment systems. Gaining control of damping Strong nonlinearities of hydraulic systems and the unpredictable operating conditions of the specific application (e.g., uneven ground, varying loads) are the main challenges to the development of satisfactory general vibration damping methods and controls. Getting real about test cycles Fuel consumption of working machines is strongly influenced by machine specification, working environment, and operator behavior, therefore a mix of several test cycles is necessary. The case for Class 8 hybrids Hybrid technology may not be the best solution for all heavy-truck applications, but a Caron Engineering expert explains how it can still benefit Class 8 vehicles.

Big fans gear up for new battles The big difference in newer commercial airplanes comes where it can't be seen: in the structure, in new materials, in the avionics, and most importantly, in the engines. Integrated Vehicle Health Management The aims of IVHM include improved safety through the use of diagnostics and prognostics to fix faults before they are an issue, as well as improve availability of fleets through better maintenance scheduling.

VW bucks hybrid convention with 2013 Jetta HEV Rather than use a mild-mannered Atkinson-cycle ICE, VW engineers opted for a turbocharger. Their unique P2 hybrid powertrain stands alone in terms of sheer driving fun balanced with efficiency. Synergies strengthen safety systems Complementary technologies and data sharing are enabling enhanced collision avoidance. For example, radar and camera sharing the same processor provides a higher level of safety than two separate systems. A 'model' instrument panel ANSYS researchers implement simulation-driven product development for thermoforming of instrument panels.

Virginia Tech rising to hybrid challenge The Hybrid Electric Vehicle Team of Virginia Tech (HEVT) is using custom motors and powertrains to re-engineer a 2013 Chevy Malibu to make it more environmentally friendly. Directing diesel's debut in U.S. Grand-Am racing Speedsource's engineering director, a Formula SAE grad from the Univ. of Florida, is helping to put Mazda's new compounded-turbo diesel engine in the Grand-Am winner's circle. Royal College of Art preps designers for expanded role Vehicle design is broadening and moving upwards in both intellectual and business terms, with many designers reaching board level, says London's Royal College of Art professor Dale Harrow. Shelby upgrades Mustang and Focus The company pumps up its Super Snake to 850 hp (634 kW) and lowers the Focus ST for Shelby-grade performance in 2013 . Vortex rocket engine reaps the whirlwind Lightweight combustion chamber walls stay cool because hot-burning propellant remains confined to a central cyclone.

BMW readies mainstream carbon-fiber vehicle structures for MY2014 The partnership with SGL Composites is already making parts for the 2014 BMW i3 and i8. AEI visited the pioneering U.S. carbon-fiber plant and witnessed a potential emerging challenger to aluminum for vehicle lightweighting. Driving a safety 'brake-through' As pressure grows for accident-free travel, EuroNCAP is pushing for widespread adoption of autonomous emergency braking (AEB) systems as a way to avoid accidents caused by late braking or braking with insufficient force. A history of leadership Ten years after completing his term on the SAE Board of Directors, Argonne National Laboratory's Donald G. Hillebrand takes on another role-2013 SAE President.

The Nano in retrospect A senior graduate student in the Department of Mechanical Engineering at the Indian Institute of Technology looks at the development of the world's cheapest car and its effect on Indian car users. A different riff on your basic two-seat electric car Markus Lienkamp, Chair of Automotive Engineering at the Technical University of Munich, is leading the Visio.M project, a German government-supported R&D effort to produce a low-cost, high-utility electric car that might attract the interest of the middle European mass market. Materials lead the way to vehicle mass reduction Reducing a vehicle's mass opens the door for a downsized engine and transmission, a lighter cradle and body structure, smaller wheels and brakes, as well as a weight-slimmed suspension. The start point for this ripple effect is materials.
