PROBLEM TO BE SOLVED: To provide a pneumatic power type injection system capable of shortening time characteristic of spraying and vaporizing fuel over all operation speed of a turbo-machine. SOLUTION: This pneumatic power type injection system 2 for injecting air/fuel mixture into the turbo-machine combustion chamber is provided with a tubular structure 4 opened at an end 4b on the downstream side to carry air/fuel mixture and having an axis XX', at least one air supply channel 6 opened for the tubular structure 4 to introduce air into the tubular structure at pressure P<SB>A</SB>, an annular fuel passage 8 formed around the axis XX' in the tubular structure 4, connected with at least one fuel supply channel 10 in which fuel flows at pressure P<SB>C</SB>, and opened at an end 8b on the downstream side in the tubular structure 4, and a means for injecting gas into at least one fuel supply passage 10. Gas has a pressure P<SB>G</SB>being higher than P<SB>A</SB>and exceeding P<SB>C</SB>to cause foaming of fuel introduced into the structure. COPYRIGHT: (C)2006,JPO&NCIPI
