High Speed Machining of CFRP Parts Investigation of the influence of new geometries, cutting datas and coolant capabilities on the surface finish of CFRP parts. State of the art: Different CFRP grades and machining conditions make geometry adjustments to the tool necessary. Mechanical failures through machining operations can be avoided in most of the cases. New unidirectional CFRP grades and dry machining processes again lead to machining problems. This study investigates new geometries to avoid heat damage with dry maching and air coolant in case of unidirectional CFRP. With help of a thermo camera and the surface investigation with a scanning electron microscope, heat damage can be analysed and therefore new geometries can be developed and tested. Target is to develop a new multi purpose CFRP geometry to meet the requirements of the future. The reduction of different geometries used leads to major cost savings.

A simulation framework with a validated system model capable of estimating fuel consumption is a valuable tool in analysis and design of the hybrid vehicles. In particular, the framework can be used for (1) benchmarking the fuel economy achievable from alternate hybrid powertrain technologies, (2) investigating sensitivity of fuel savings with respect to design parameters (for example, component sizing), and (3) evaluating the performance of various supervisory control algorithms for energy management.

Many manufactures are currently working on solutions to fulfill CARB MY 13 requirements for monitoring of diesel particulate filters using a soot sensor. Europe might follow by introducing new OBD limits with EU6 regulation. In this presentation we show results from a study investigating the monitoring capability of a soot sensor in combination with EU6 emission calibration and the OBD matriculate mass limit as proposed in EC 595/2009. A defective diesel particulate filter (DPF) has been detected on roller test bench and under normal driving conditions on public roads. Calibrating a precise soot model is the key factor for the reliability of the particulate filter diagnosis using a soot sensor. Presenter Thomas Czarnecki, Bosch Engineering GmbH

While providing significant benefits to vehicle operation and emissions, on board diagnosis comes at a cost. In many cases the additional cost comes in the form of reduced optimal performance. Often the additional cost can be mitigated by considering the OBD requirements early in the development stages. In this presentation we show these trade-offs in a number of case studies. We will point out where the ability to diagnose comes at the cost of suboptimal performance, and where system design decisions can facilate the OBD task. Presenter Michiel Van Nieuwstadt, Ford Motor Co.

It is a challenge to write a good motor specification. Typical spec. problems are omitted or ambiguous requirements, or overly tight tolerances that drive up cost but not value. These problems create hidden penalties in cost, performance, reliability, and development time. This presentation will describe common problems in traction motor specifications and associated penalties, as well as recommendations to avoid them. Topics will include spec.?s for demagnetization, mechanical considerations, torque ripple, performance, and others. Presenter David A. Fulton, Remy Inc.

“Spotlight on Design” features video interviews and case study segments, focusing on the latest technology breakthroughs. Viewers are virtually taken to labs and research centers to learn how design engineers are enhancing product performance/reliability, reducing cost, improving quality, safety or environmental impact, and achieving regulatory compliance. In the episode “Diagnostics and Prognostics: Proactive Maintenance and Failure Prevention” (21:04), Delphi engineers explain how they leverage the growing number of sensors and computing power in vehicles to diagnose and proactively solve emerging mechanical or electronic problems, before a breakdown occurs. This video also looks at the next generation of automotive telematics, with HEM Data demonstrating how in-vehicle data acquisition is used to monitor the inner workings of vehicles.

For internal combustion engines and industrial machinery, it is well recognized that the most cost-effective way of reducing energy consumption and extending service life is through lubricant development. This presentation summarizes our recent R&D achievements on developing a new class of candidate lubricants or oil additives ionic liquids (ILs). Features of ILs making them attractive for lubrication include high thermal stability, low vapor pressure, non-flammability, and intrinsic high polarity. When used as neat lubricants, selected ILs demonstrated lower friction under elastohydrodynamic lubrication and less wear at boundary lubrication benchmarked against fully-formulated engine oils in our bench tests. More encouragingly, a group of non-corrosive, oil-miscible ILs has recently been developed and demonstrated multiple additive functionalities including anti-wear and friction modifier when blended into hydrocarbon base oils.

The U.S. Environmental Protection Agency (EPA) contracted with FEV, Inc. to estimate the per-vehicle cost of employing selected advanced efficiency-improving technologies in light-duty motor vehicles. The development of transparent, reliable cost analyses that are accessible to all interested stakeholders has played a crucial role in establishing feasible and cost effective standards to improve fuel economy and reduce greenhouse gas (GHG) emissions. The FEV team, together with engineering staff from EPA's National Vehicle and Fuel Emissions Laboratory, and FEV's subcontractor, Munro & Associates, developed a robust costing methodology based on tearing down, to the piece part level, relevant systems, sub-systems, and assemblies from vehicles ?with and without? the technologies being evaluated.

With automotive electrification, the electric machines show a tendency to share or even replace the dominant role of internal combustion engines in future vehicles. Besides the design and innovation of different electric machines to meet the needs of powertrain and drivetrain performances, high volume production becomes a challenging topic and an un-avoided requirement. Flexible line and sharing line will help the variation of production rate and volume, while the dedicated unique line contributes to large scale of E-motor production. Supplier chain from raw materials, parts to processes has to be built from ground-zero or low grade to mature stage within quality specification and time limitation. Multi function skills, cross area technologies and complex management etc are all required for E-motor manufacturer to grow up with component and equipment suppliers. Reducing cost, improving quality and guaranteeing safety are always the thematic series.

This paper forms the third of a series and presents results obtained during the testing and development phase of a dedicated range extender engine designed for use in a compact class vehicle. The first paper in this series used real world drive logs to identify usage patterns of such vehicles and a driveline model was used to determine the power output requirements of a range extender engine for this application. The second paper presented the results of a design study. Key attributes for the engine were identified, these being minimum package volume, low weight, low cost, and good NVH. A description of the selection process for identifying the appropriate engine technology to satisfy these attributes was given and the resulting design highlights were described. The paper concluded with a presentation of the resulting specification and design highlights of the engine. This paper will present the resulting engine performance characteristics.

In Oct. 2011, Nissan announced its new six-year environmental plan, Nissan Green Program 2016 (NGP 2016), that includes initiatives to lead fuel efficiency: 35% fuel economy improvement compared with 2005 on a corporate average for all Nissan vehicles sold in Japan, China, Europe and the United States. To achieve this target, we`re planning to launch products delivering class-leading fuel efficiency such as an all-new FWD hybrid model, Introducing a next-generation continuously variable transmission (CVT).
