Recently, particulate matter (PM) emission regulations are becoming more strict for diesel engines. There is increasing interest for measuring not only concentration, but also size of the particles. Laser -induced incandescence (LII) has emerged as a promising technique for measuring particle volume fraction and size. In this study, Simple time resolved LII (TIRE-LII) method was applied to the simulated exhaust of Ethylene diffusion flame as a preliminary test for measuring diesel exhaust PM emissions. The particle size results from LII technique were calibrated via field emission scanning electron microscope (FE-SEM) photograph. The inaccuracy of particle sizes between LII measurement and FE-SEM photograph was within 4.3%.
