Feasibility of Seismic Monitoring at a Potential CO2 Injection Test Site in the Paris Basin

Seismic effects of the injection of CO2 into a partially depleted oil field have been evaluated. Seismic modelling yields small time-lapse effects, including 0.4 ms time-shifts and 4 to 6% amplitude variations at the top and bottom of the reservoir. Amplitude variations at the reservoir level should be slightly larger at large incidence angles, but wave equation modelling shows...

A Simulation Study of the Impact of LP EGR on a Two-Stage Turbocharged Diesel Engine

Current engine development projects have to face crucial challenges: raw pollutant emission reduction while maintaining or even reducing the engine fuel consumption. To solve this issue, several technologies have been studied and some can offer part of the solution. Among these technologies, turbochargers provide one of the best trade off. Different turbocharging technologies can...

Cold Start on Low Compression Ratio Diesel Engine: Experimental and 3D RANS Computation Investigations

Diesel enginesLes futures normes d'émission concernant les moteurs Diesel imposent une réduction importante des émissions polluantes à la source, avant les dispositifs de post-traitement.

3D CFD Analysis of an Abnormally Rapid Combustion Phenomenon in Downsized Gasoline Engines

Soaring oil prices combined with increased environmental awareness maintain the drive for fuel-efficient and CO2-friendly powertrains. Even if hybrids seem to be the media friendly solution, there is still much work to be done on combustion systems. For gasoline engines aggressive downsizing seems promising and IFP proposes an innovative approach. However, new difficulties arise...
