<p>PURPOSE:To make it possible to carry out stable combustion with less amount of fuel, by providing such an arrangement that a primary air passage is formed in the outer periphery of a fuel injection port provided with a fine pipe, and the combustor has an inside and outside double shell structure having a space in which secondary and ternary air passages are formed. CONSTITUTION:A fine pipe 103 is provided to the jet port 101 of a fuel injection valve, and a primary air passage is formed in the outer periphery of the jet port 101. The combustor is formed in an inside and outside double-shell structure, and secondary and ternary air passages 153, 154 are formed in a space between inner and outer cylinders 151, 152. The wall surface of the inside cylinder 151 in the vicinity of the jet port 101 is formed as an inclined wall surface having a spreading angle corresponding to the injection angle of fuel. Secondary air communication holes 155 are formed in this inclined wall surface, and ternary air communication holes 156 are formed in the outlet wall surface of the inner cylinder 151.</p> |
