In order to reduce emission of diesel participate matter, of which soot is a major component, it is important to understand the soot morphology and nanostructure. This study aims to observe soot particles directly sampled in diesel spray flame using high-resolution transmission electron microscope (HRTEM). Carbon-coated copper grid was placed in the combustion chamber and was directly exposed to the diesel spray flame. Behavior of diesel spray flame intruded by the soot sampler was observed by high-speed laser shadowgraphy and direct photography. HRTEM observation of the grid showed that soot was successfully collected onto the grid.
