CODE-I
International Consortium Study 2010-2012 - New announcement
|
|
This program, initially announced in 2009 and aimed at improving cold operation and emissions for diesel engines, will be launched this year. Today, a clearer visibility of the diesel engine emission requirements complying with future standards emphasizes the need to investigate further the whole cold operation issue.
Therefore, in view of the regulatory context for diesel engines, on the one hand, and the need to extend the study to cover the broadest possible range of cold operations (cold start and idling, cold operation at -7°C and pollutant emissions), on the other, IFP Energies nouvelles has decided to revise its original technical program.
The main objectives remain the same: to gain a better understanding of and characterize the cold operation of diesel engines, including partial load at -7°C.

Challenging destructive pre-ignition in highly charged spark ignition engines
|
|
Stochastic and violent forms of pre-ignition have occurred at low engine speeds and high charging pressures close to full load since turbocharged gasoline engines were first developed. Although this phenomenon has some similarities to knocking, it can be so violent that a single occurrence can destroy the engine. One of the major challenges facing car manufacturers involves identifying the mechanisms behind this abnormal combustion in order to guarantee maximum performance for the highly turbocharged spark ignition engines of the future.
IFP Energies nouvelles approach: Visualization and advanced statistical analysis
IFP Energies nouvelles has demonstrated the significant value of combining statistical analysis and direct visualization. Advanced statistical analyses of the combustion process and direct visualization inside the combustion chamber are successfully combined to accurately assess the development of pre-ignition. This coupled approach provides an efficient tool for the analysis and development of new engines and new control concepts on test benches.
IFP Energies nouvelles has adopted a structured and original method based on a better understanding of the phenomenon but also on an accurate control of combustion at high load to detect each occurrence of pre-ignition.
Statistical analysis
IFP Energies nouvelles has developed a statistical approach to define new reliable indexes and methodologies enabling quantification of the frequency and intensity of pre-ignition. As a result, it is possible not only to evaluate the impacts of an engine's settings and technical definition but also to avoid massive bulk auto-ignitions thanks to precise quantification of all intermediate pre-ignitions as soon as combustion begins to deviate.
Direct visualization
CCD cameras are used to visualize pre-ignition in the combustion chamber and to determine the spatial origin of pre-ignition. A high-speed camera offers the advantage of gathering a lot of images in one cycle and helps to increase the productivity of results.
These two innovative statistical approaches define new reliable indexes and methodologies enabling precise quantification of pre-ignition frequency. It is possible to compare different configurations and to guide the design of new engines on test benches. It is also conceivable to transpose some of these tools for online analyses, either for steady-state operations or for transients.

Alternative fuels for the aeronautics industry
|
|
The constant rise in air traffic is set to result in a three-fold increase in associated CO2 emissions by 2050. One of the solutions under consideration is the partial replacement of kerosene with more environmentally-friendly alternatives and IFP Energies nouvelles is investing significant resources in this area of research.
Using its expertise in the field of fuels and engines, IFP Energies nouvelles is working to identify and develop appropriate substitutes. However, kerosene is not just another oil product: flights are intercontinental and as such fuel quality must be consistent throughout the world. Moreover, it has to have specific properties due to the conditions in which it is used: outstanding performance at cold temperatures, high energy content. Finally, it has to be able to provide all the guarantees required as regards flight safety.
Given these constraints, the process of finding a substitute fuel is a highly complex one and research has now turned to the potential use of drop-in fuels, i.e. a fuel chemically similar to kerosene that can be combined with kerosene and used at any time and in any proportion, without needing to modify aircraft.
Considerable resources are currently being devoted to alternative fuel research throughout the world and some of the first solutions identified have already been authorized for commercial use. For example, fuels developed using ex Fischer-Tropsch processes – 50% mixture with standard kerosene – are authorized provided they meet the strictest specifications.
IFP Energies nouvelles has been involved in numerous national and European research programs focusing on aeronautics fuels. These programs cover alternative processes, the validation of solutions via materials compatibility tests, product and production expertise, as well as economic and lifecycle analyses.
IFP Energies nouvelles is also involved in projects focusing on the production of alternative fuels using different processes such as the hydrotreatment of oils, BtL technologies and liquefaction. The BioTfuel project, for example, which runs to 2017, aims to develop BtL technologies and the BtL industry as a whole, making it possible to obtain low-CO2 kerosene in particular.
One of the most promising solutions – that can be implemented in the short term – consists in taking vegetable oils (jatropha, camelina, etc. and, in the longer term, algae) and subjecting them to a hydrotreatment process. These oils can then be transformed into paraffins from which fuels can be produced, particularly kerosene. IFP Energies nouvelles is continuing the development of a process that is set to be marketed by its subsidiary Axens in the next few months. The advantage of hydrotreated vegetable oils (HVO) is that they are associated with low CO2 emissions.
