The structure and the soot surface growth and surface oxidation properties of round laminar jet diffusion flames were studied experimentally. Measurements were made along the axes of acetylene/argon-fueled flames burning at atmospheric pressure in coflowing oxygen/argon mixtures to provide higher temperature soot-containing regions (2000–2350 K) than were considered during earlier work. The measurements yielded soot surface growth and surface oxidation rates as well as the flame properties that are thought to control these rates.

This study investigates the engine performance and exhaust emission of the dual-fuel operation on a single cylinder compression ignition engine from the energetic, exergetic and sustainability points of view using experimental values. Hydrogen with different concentrations is used as fuel with diesel as the main fuel. Comparative results of the dual-fuel operation with conventional diesel fuel through experimental results demonstrated its benefits for the engine performance.
