PROBLEM TO BE SOLVED: To reduce the occurrence of a fluctuation in a pressure in a chamber and to minimize the generation of vibration of a combustion chamber. SOLUTION: A three-stage lean combustion chamber consists of a primary combustion region, a secondary combustion region, and a tertiary combustion region. First fuel injectors 64 and 66 inject fuel against first and second spirally winding apparatuses 60 and 62. The first fuel injectors 64 and 66 and the first and second spirally winding apparatuses 60 and 62 are formed that an air-fuel ratio between fuel and air flowing from the passage of the first spirally winding apparatus 60 is different from an air-fuel ratio between fuel and air flowing from a passage 65 of the second spirally winding apparatus 62 to the primary combustion region. This constitution distributes fuel in the primary combustion region in an axial direction and reduces the generation of vibration injurious to a combustion chamber. |
