Main topics are the development and the build-up of an 18ton hybrid truck with a parallel hybrid drivetrain. With this truck it is possible to drive up to 3 kilometers in the pure electric driving mode. Presenter Andreas Eglseer, Engineering Center Steyr GmbH & Co. KG

EGR coolers are used in combustion engines to reduce NOx emissions. However, heat transfer in these coolers also results in thermophoresis-temperature-gradient driven motion of suspended particles towards cooler regions-which leads to significant soot deposition. Presenter Meisam Mehravaran

The Focus Electric is Ford�s first full-featured 5 passenger battery electric vehicle. The engineering team set our sights on achieving best-in-class function and efficiency and was successful with an EPA certified 1XX MPGe and range XXX then the facing competition allowing for a slightly lower capacity battery pack and larger vehicle without customer trade-off. We briefly overview the engineering method and technologies employed to deliver the results as well as sharing some of the functional challenges unique to this type of vehicle.

The rapid pace of recent progress in vehicle electrification technologies points to a bright future for electric-drive vehicles, but uncertainty regarding future technical trajectories and uncertainty in consumer response make possible a multitude of electric-drive vehicle futures. This presentation will examine a range of these possible electric-drive futures as a function of different technology and pricing scenarios. An exploration of initial conditions, market uptake, and resulting social benefits will show how HEV and PEV technology enable the attainment of stringent vehicle efficiency goals and unlock potential for lower-carbon futures.

Optical fiber has begun replacing copper in avionic networks. So far, however, it has been mainly restricted to non-critical applications (video transmission to the flight deck, IFE?). In order to take advantage of the high-bandwidth, low weight, no EMI properties of optical fibers in all data transmission networks, it will be necessary to improve the testing. One part of the puzzle, which is still missing, is the self-test button: the possibility to check the network and detect potential failures before they occur. The typical testing tool of a technician involved in optical fiber cables is the ?light source ? optical power meter? pair. With this tool, one can measure the insertion loss of the fiber link. A second important parameter, the return loss at each optical connector, is not analysed. In addition, this is only a global measurement, which does not allow the detection of possible weak points.

By introducing the concept of a separation between graphics and logic, interpreted run time architecture, and defined communication protocol, the ARINC 661 standard has addressed many of the concerns that aircraft manufacturers face when creating cockpit avionics displays. However, before kicking off a project based on the standard, it is important to understand all aspects of the standard, as well as the benefits and occasional drawbacks of developing with ARINC 661 in mind. This white paper will first provide an overview of ARINC 661 to clarify its concepts and how these relate to the development process. The paper will also describe the benefits of using a distributed development approach, and will outline practical, real world considerations for implementing an ARINC 661-based solution. Finally, readers will learn how commercial tools can be used to simplify the creation of displays following the standard to speed development and reduce costs.
