Zhiqin Jia Outline Background & goals Experimental setup Methodology Results Conclusion & future work

Zhiqin Jia Background Research regarding conventional NG-Diesel dual-fuel combustion have already continuously been conducted several decades (NG mass ratio, total lambda, pilot Diesel quantity influence, etc). Dual-fuel RCCI (Reactivity Controlled Compression Ignition) combustion concept gives quite promising results (efficiency and emission). There is a need for dual-fuel 3D models to help to optimise dual-fuel experimental hardware and understand more about combustion details. Roussos G. Papagiannakis, ”Combustion and performance characteristics of a DI diesel engine operating from low to high natural gas supplment ratio”, SAE Technical Paper: Derek E. Nieman and Rolf D.Reitz, ”Heavy-duty RCCI operation using natural gas and diesel”, SAE Technical Paper:

Zhiqin Jia Goals Investigate dual-fuel (NG/Diesel) RCCI fast combustion on a heavy duty DI Diesel engine. Validate Chalmers developed dual-fuel combustion 3D simulation model with experimental data.

Zhiqin Jia Conclusions & Future work It has been shown that RCCI combustion can be obtained and controlled for mixtures of NG and Diesel. It is possible to reach very high thermal efficiency and low NO x and Soot emissions. Resonable good agreement between the experimental data and 3D simulation model have been achieved, but chemical mechanism needs to be further improved. We plan to investigate direct injection of both gas and Diesel.
