Ultra Light Vehicles (ULV) intrinsically have a better efficiency due to their improved transport capability per vehicle mass. Additionally improved driving dynamics performance can more easily be achieved because of the reduced mass. However, the design of ULV sharing the same road with heavier cars represents a complex technical challenge for achieving acceptable safety levels. Furthermore, at present the additional purchase costs of a pure battery electric vehicle one as compared with a gasoline is more than 15000 Euros. Consumers buy a new vehicle because many and diverse reasons, including purchase price (one of the main concerns of the majority of buyers when approaching to purchase a new vehicle), depreciation rate, styling, performance and handling, brand preference and social image. However, car owners tend to underestimate the costs of running a vehicle. Although they are very well aware of fuel costs, road tax and insurance, they do not always account for servicing, repair and cost of depreciation. Therefore, if one is interested in comparing the cost of EV with other competing vehicle technologies the parameter of interest should be the Total Cost of Ownership (TCO). The project proposal AMBER-ULV aims to develop and integrate several innovative concepts, resulting from successfully completed R&D projects, giving a socially acceptable answer to safety concerns but not penalising the driving experience.

To enable a large scale adoption of EVs, a new generation of electric drive systems is needed to reduce dependency on rare earth materials, while improving energy efficiency, power density, safe operation and reducing manufacturing/recycling costs. ARMEVA will develop a new rare-earth-material free generation of advanced reluctance motors. The goal of ARMEVA is to achieve similar power density and NVH-performance (Noise, vibration, and harshness) at lower costs when compared to permanent magnet motors in real electric vehicle applications. The focus will be on Switched Reluctance Motors, Variable Reluctance Synchronous Motors and DC exited flux-switching motors which each have been the topic of previous research by the consortium, and offer promising potential. The scientific objectives of the ARMEVA project are:(i) development of multiphysics simulation models for advanced reluctance motors; (ii) comparative assessment to select optimal motor topology for future EVs; (iii) development of an integrated electric drive system based on advanced reluctance motor technology and customized power electronics. ARMEVA will be executed through 5 linked RTD WPs: starting with requirements mapping at vehicle level, followed by concept analysis & specification, after which the motor concept and the power electronics & controls are developed. The entire system consisting of control software, power electronics and a physical electric motor will be integrated and validated in a vehicle platform. The partners will manage the project as necessary (WP7), and roll out a well thought-out plan for the dissemination and communication (WP6). ARMEVA will use a system based approach using multi-attribute techniques to improve the overall concepts and multi-application, multi-operation analysis to optimize vehicle level efficiency in a wide range of realistic conditions. The ARMEVA consortium (incl. SME, Tier 1 and RIs) has been carefully defined to cover all fields of expertise necessary

The objective of the research program is to design, optimize and develop a space plasma thruster based on helicon-radio-frequency technology and its application to a nano-satellite for attitude and position control. Moreover a detailed feasibility study will be also conducted to evaluate the possibility of using the plasma thruster to heat and decompose a secondary propellant. The feasibility study will asses the possibility of building up a combined-two-mode-thruster able to operate in the low-thrust high-efficiency plasma-mode and high-thrust low-efficiency secondary-propellant-plasma-enhanced mode. Only the plasma thruster will be developed and fully tested during this study. The main characteristics of the thruster are: Power 50 W Weight within 1.5 kg Thrust >1.5 mN Specific Impulse (Isp) >1200 s The program will develop thought the following steps: a) Deep numerical-theoretical investigation through dedicated plasma-simulation tools. b) Extensive experimental campaign to validate codes, to investigate the physics phenomena involved and to proof thruster performance. c) The development of a thruster-prototype to be mounted on board of a mini-satellite to demonstrate technology feasibility, d)The study of all the critical issues related to the application to a mini-satellite e) the design and manufacturing of the mini-satellite mock up including all critical components f) analysis of scaling law to lower and higher power. As a final results of the project, a detailed analysis will be conducted in order to evaluate the possible application of the thruster in space missions requiring low thrust accurate attitude and position control.

Today climate change causes serious problems to the societies worldwide and Europe starts to feel its consequences. At the same time European community is facing economical problems. One of the main producers of greenhouse gases is the non sustainable energy production and use. Therefore there is an urgent need to reduce energy use in most cost effective way. PLEEC will gather cities with innovative planning and ambitious energy saving goals. It will identify technology, citizens behaviors and structure driven efficiency potentials within urban planning and key city aspects. PLEEC will assess the status of energy efficiency and energy flows in the participating European middle size cities. It will improve understanding of basic conditions for energy efficiency in the cities through joint activities between city planners and researchers on technology, citizens behavior and structures. By finding the optimal mix of all energy efficiency measures the model for strategic sustainable planning will be created together with the action plans for implementation and management. The model and the action plans will address key aspects relevant for the whole city. They will be supported by the public authorities on the highest political levels. Analysis of time line, the costs and pay-back periods will be done based on different regulatory and market conditions of the participating cities. The model will guide the cities to find the most cost effective implementation of the EU SET-Plan goals to reduce energy use in EU by 20% till 2020.

Acoustics influence on internal combustion engine volumetric efficiency is obvious and the use of modeling to represent its effect is largely spread. In this regard, LMS has developed a new 1D model library, namely CFD1D, to model engine intake and exhaust lines under LMS Imagine. Lab AMESim platform. Simulations have been performed at IFP Energies nouvelles (IFPEN) to compare duct system modeling with two different approaches: on the one side, with the brand new 1D library and on the other side, with state-of-the-art 0D lumped parameter models (IFP-Engine library under the same platform). This paper aims at comparing 0D and 1D modeling strategies for two naturally-aspirated spark-ignition engines: a single-cylinder propane-fueled engine and a Honda K20A engine with a dedicated intake system used for a cylinder deactivation concept development. For each application, a 0D and a 1D intake system model is realized, based on real engine test-bed geometry. The line description of the system geometry is performed either with multiple 0D pipe models representing mass transfers or with 1D elements accounting for full acoustics phenomena. Each type of line description is associated with the same combustion model for each application to obtain a sound comparison on steady-state operating points. Calculated pressure traces in pipes are in good agreement with high frequency test bench measurements for both engine cases and modeling approaches. Finally, a comparison of the modeling approaches is provided in terms of accuracy and CPU time consumption. © Copyright 2011 Society of Automotive Engineers of Japan, Inc. and SAE International.
