When there are fire compartments, the decision-making of emergency response are mainly based on human decisions, the result of experience and voluntarism, without a full understanding of its evolution over time. In the fight against the fires, knowledge of their dynamics and their hazards and the ability to measure, communicate and interpret the variables that characterize constitute essential elements in assessing the situation to organize optimize and secure emergency. This is the challenge of this project whose objectives are to determine by experimental and numerical specific laws governing phenomena compartment fires and in a second phase approach from these laws, migrating systems current liabilities to safety and intelligent communication systems , optimizing and securing the human and organizational emergency response.

One way to significantly reduce carbon emissions in transport is to consider the development of hybrid and electric vehicles. Thus, the use of power converters will rapidly increase in modern vehicles. In order that the introduction of power converters in transport vehicles be done in harmony with the low-level systems as well as constraints related to human exposure to electromagnetic fields, it has become fundamental to anticipate the behaviour of EMC in power systems at a very early design stage. As such, this project is a continuation of SP4 program O2M and therefore proposes to continue the development of tools to take into account EMC in static energy convertors. For memory the SP4 O2M has treated the problem of active power component description in time and frequency domains, the near-field coupling between electronic components and taking into account the effect of temperature. The result is the ability to obtain a reliable model for a power module. These models will be completed by those of harnesses and of motors / actuators. Also a big effort will be made to the propagation phenomena and the development of optimization tools. The goal now is to go into modelling a subsystem that is to say a system composed only of the power module, a beam and an actuator / motor. This model will allow the search for optimum configuration. The proposed methods must be adaptable to rapid modelling required during the pre-sizing or simulations more time-consuming giving access to quantitative results. We will study aspects including system modelling and global optimization.

Project DIVAS aims to identify promising and innovative technological ways in order to cut off CO2 emissions (by 10%) on Diesel engines. Strong downspeeding approach is addressed, in order to overcome scientific and technological locks in air loop management (increasing air filling for low end torque). Considering results already obtained by simulation, two concepts with strong potential have been identified ; target of the project is to explore more deeply these concepts, by advanced dedicated research and experimental work on adapted engines : - compressor (mechanical clutching compressor or electric compressor) + turbocompressor : this new technological way allows high increase of air filling, with benefits in CO2 emission. We propose to study and adapt prototype engine (adaptation of air loop) with advanced control strategies in order to take maximum advantage of air path, to study current technological locks (drivability, compressor drive power...) and to confirm potential on experimental tool - variable valve actuation + turbocompressor : innovative concept of variable valve actuation is proposed in order to allow scavenging (enhancing turbocharging and air filling) without penalties well known in Diesel engines (deep valve pockets in piston). We propose to validate on experimental engine good results obtained in simulation, identifying transient behavior and explore more in details concept in par load operation : lowering fuel / air ratio, after treatment control. Coupling these two techniques will be performed at the end of the program, after identification of synergies. This project is complementary to Synergy project, that aims to perform downspeeding but with different technological ways (2-stage turbocharging, VVA for part load operation). Moreover, experimental tools share some features (combustion system, generic VVA definition on K9 multi cylinder engine), that helps to better identify benefits and drawbacks of each approach and dramatically reduces costs linked to conception and tests.
