This paper describes the initial experiments and computational simulations aimed to measure and quantify the level of nano-sized particulate production from combustion in low temperature combustion (LTC). This work measures nano-sized particles in a laminar ethylene flame both by the use of small-angle x-ray scattering at the Advanced Photon Source and through a technique called thermophoretic sampling. Future experiments will perform similar measurements in a Rapid Compression Machine under conditions typical for HCCI engines. The simulation work involves the use of coupled Computational Fluid Dynamics (CFD) and Chemistry Kinetics codes to predict the fuel/air mixture composition and temperature distribution in the combustion region and directly complements the experimental work. The results show that nano-particles are created under rich, premixed conditions, even with low temperature reactions (T<2000K).
