Investigation on Characteristics of Lean Limit Flame in a Closed Bomb 2001-28-0011

Form the viewpoint of low air pollution and energy saving in the internal combustion engines, experiments have been carried out to examine the characteristics of flame propagation near the lean limit mixtures in a closed bomb by using the microgravity techinique. The true flame characteristics is examined by realizing the spherical flame propagation in a closed bomb under microgravity. Furthermore, the effect of hydrogen added in lean limit mixtures and improvement of the reflectivity of the internal surface wall of the combustion bomb are studied to enhance the flame propagation speed of lean limit mixtures.
