Pollutant Emissions Reduction of Internal Combustion Engines by using Alternative Fuels and Enhanced Ignition Systems
Radu Chiriac, University “Politehnica”, Romania
Abstract: The researches performed for improvement of internal combustion engines performance using alternative fuels and enhanced ignition systems will be discussed. These approaches address the concerns about availability of petroleum derived fuels and pollutant emissions level.
Radu Chiriac graduated in 1982 the Faculty of Mechanical Engineering from University “Politehnica” of Bucharest. He obtained his PhD Diploma in 1995, from the same university, in the field of thermal equipment-internal combustion engines. Currently, Radu Chiriac is full professor at Department of Thermodynamics, Heat Engines Thermal and Refrigerating Equipments from “Politehnica” University. Since 2010 he is associated member of Chaire de Turbomachines et Moteurs from Conservatoire National des Arts et Métiers, Paris. He is member of The Society of Automotive Engineers, USA. His research activities are related to alternative fuels for internal combustion engines, combustion investigation, simulations of the internal combustion engines processes, heat transfer and fluid dynamics.

Nonequilibrium Plasma-Assisted Combustion: Advanced Spectroscopic Methods for Fundamental Studies
Abstract: Non-equilibrium plasmas have strong potential to enhance performance of combustion systems due to generation of large numbers of reactive species. Kinetic and dynamic fundamental studies using advanced spectroscopic diagnostics are presented.
Gabi Daniel Stancu obtained his PhD in plasma spectroscopy at University of Greifswald, Germany in 2004. He was then a research fellow in a couple of academic institutions, and since 2010 he is an associate professor at Ecole Centrale Paris, France, today CentraleSupélec. His current activity is devoted to development of advanced spectroscopic diagnostics for non-equilibrium plasmas and to understanding of fundamental kinetic and dynamic mechanisms in reactive plasmas, in particular in plasma-assisted combustion.

The Evolution of Laser Ignition over Four Decades
Abstract: Laser spark ignition of reactive gases was first attempted in 1969; one decade later first engine tests were achieved. Several concepts for an ignition scheme including fiber transportation of ns pulses were pursued successfully. A number of different prototypes, mostly Nd:YAG lasers, transversally or longitudinally, directly or fiber-transmission pumped were developed. Studies have shown that the problem of window failing can be avoided. The temperature management for the solid-state as well as the diode lasers still represent major problems in laser ignition of car engines to date.
Ernst Wintner received his PhD in Physics in 1976 from University of Vienna with a thesis on “Electron Microscopy of Partial Dislocation Structures in CuAl Alloys”. He changed to the field of Photonics when joining TU Vienna in 1976. In 1992 he was promoted titular full professor of Applied Laser Technology; since Oct. 2015 he is retired. His scientific work comprises nonlinear optics, fiber optic sensors, solid-state lasers, ultra-short pulse generation, and applications in materials processing and dental medicine. Together with GE Jenbacher, Austria, he founded the Laser Ignition Research Group in 1998. His external activities comprise visiting scientist at M.I.T. 1982 - 1984 and at Friedrich-Schiller-University, Jena in 1986, Visiting Professor to Institute of Laser Engineering, Osaka University, 2000-2001, and Indian Institute of Technology Kanpur in 2013. He is (co)author of more than 250 scientific publications including 7 book chapters and member of several professional organizations.
