Cylinder deactivation : the OVaLiD® concept
A new approach for variable displacement
|
|
In parallel with downsizing or even high downsizing, domains in which IFP has been largely involved, the latest developments have focused on cylinder deactivation, which is another attractive way to improve SI engine efficiency and finally to reduce CO2 emissions, while keeping conventional aftertreatment systems. All these features make cylinder deactivation a cost-effective solution.
For this reason, IFP has developed a new concept of cylinder deactivation: OVaLiD®. This concept is based on optimised valve lift strategy, and its development has been particularly oriented for application on 4 cylinder engines, the target for lowest CO2 emissions. The OVaLiD® concept avoids the main drawbacks of conventional valve deactivation and offers fuel saving potential of up to 15% in case of naturally aspirated engines. It can also be applied to V6 or V8 engines resulting in comparable benefits, and when coupled to downsizing, CO2 savings up to 25% are expected.

SCR to comply with Euro 6
|
|
Urea SCR (Selective Catalytic Reduction) of nitrogen oxides emitted by Diesel engines is one of the most promising ways to comply with the upcoming Euro 6 emission regulation for passenger cars in Europe, as well as for the Tier2 bin5 standard in the US. In a research program achieved by IFP, PSA Peugeot-Citroën and ADEME (French Environment and Energy Management Agency), a complete SCR exhaust line was designed for a 2.0 l Diesel engine to address the targeted NOx emissions while minimizing the urea consumption. Specific attention was paid to undesirable species such as ammonia and N2O, but also to the part of NO2 in the remaining NOx that is, in most cases, significantly decreased.
Dedicated AdBlue® injection strategies were developed to maximize the part of ammonia available for deNOx reactions, especially in the low temperature conditions where the preconditioning of the zeolite catalyst is crucial.
Due to an efficient activity all over a large temperature range, urea SCR should also permit the achievement of some extra NEDC NOx reduction, with an embedded AdBlue® tank no larger than 20 l. Thus, AdBlue® refilling would not be required between the scheduled maintenance intervals of the vehicle.

17th Aachener Kolloquium - "Automobile and Engine Technology"
6-8 October 2008 |
|
This congress gathered more than 1800 participants from 25 different countries. IFP had the opportunity to present, within the "Combustion concepts EGR&VTT" session, its latest developments with a shared publication with Renault and Mechadyne: "Comparative study in LTC combustion between a short HP EGR loop without cooler and a variable lift and duration system".

International Conference on Advances in Hybrid Powertrains 25-26 November 2008 |
|
This scientific conference, jointly organized with TNO, focused on the medium-term development of hybrid powertrains for passenger cars, commercial vehicles, buses, and delivery trucks. Two hundred participants from academic research and industry debated on the potential technologies in areas such as engine control or complete real-time simulation.

IFP Sessions on LES for Internal Combustion Engine Flows
1-2 December 2008 |
|
Industry and research gathered at IFP for this two-day conference to discuss the use of Large-Eddy Simulation (LES) applied to internal combustion engine (ICE) flows, injection and combustion.
It was an opportunity for the participants to compare their views on the state of the art in LES and on the future research to be implemented.
The next conference will be held in 2010.

Discussions are currently going on among the potential partners of the new IFP consortium "DUST-EGR" in order to finalize the technical program. DUST-EGR, to be launched in early 2009, will focus on the understanding and solutions for EGR systems.
IFP has developed a first physical model for Ni-MH batteries coupling an electrochemical and electrical approach. This model was obtained at the end of experimental tests comprising conventional loading/unloading cycles and electrochemical impedance spectroscopy measurements. This has lead to an estimation of the internal battery resistance and the identification of some electrochemical processes involved. The development and the validation of Li-ion type battery models are also under progress.
In addition, IFP is developing control algorithms intended to evaluate the state of charge (SoC) of the battery validated through AMESim/Simulink co-simulation: a first step towards the development of a BMS (Battery Management System).
Within the scope of the Energy Technology Plan (SET Plan) proposed by the European Commission, IFP has co-organised with the CEA the conference "Towards a low carbon energy". This conference which took place on the 28th of October in Paris, aimed at preparing the implementation of the SET Plan for a better efficiency of research and innovation in Europe.
More than 500 high level policy makers, representatives of Members States and of the European Commission, Members of Parliaments, directors of research organisations and of the energy sector have participated in this major event.
IFP has submitted several projects in response to the 2008 FP7 (Seventh Framework Programme of the European Commission) call for proposals. Hybrid powertrains, embedded systems, aeronautic combustion simulation, aeronautic alternative fuels are amongst the future potential fields of collaboration with industrial and academic partners.
Renault's TCO vehicle demonstrator
"Through the powertrain transverse group, this fast but no less effective cooperation between Renault and IFP was driven by a very constrained planning. After 9 months, the baby TCO was applauded by the different Renault divisions. IFP has demonstrated its know-how in terms of compromise and adaptability for the benefit of the Total Cost of Ownership."
