PURPOSE:To reduce smoke, particulate, and NOx. CONSTITUTION:A deep section 24 and a shallow section 26 are arranged alternately in regions 11 to 14 where a combustion chamber 15 is divided into four in peripheral direction. Longitudinal injection holes 17, 19 which face the deep section 24 and lateral injection holes 16, 18 which face the shallow section 26 are formed in a combustion injection nozzle 20 to inject a longitudinal fan type spray L1 and a lateral fan type spray L2 into each region 11 to 14. Thus, disturbance of air T which flows from a bottom face 23 of the deep section 24 to a bottom face 25 of the shallow section 26 is formed in the combustion chamber 15 in addition to swirl S and skish K. Consequently, the mixture of fuel and air is promoted, and uniform combustion is done.
