There is provided an engine (10) including a gas turbine unit and a plurality of combustion units (80) that supplies combustion gas (51) to the gas turbine unit. Each of the combustion units (80) includes: a combustion chamber (11); a first mechanism (71) that moves a first wall surface (81a) that configures a part of the combustion chamber, using an elastic force of a spring (83) to reduce a volume of the combustion chamber (11) and pressurize a gas (58) inside the combustion chamber; and a second mechanism (72) that opens and closes an exhaust port (85) of the combustion chamber to control the timing at which combustion gas (51) is discharged from the exhaust port.

A combustor assembly for a turbine engine includes a combustor assembly where a first combustion space is defined between a first closed end of a combustion chamber and a first piston, a second combustion space is defined between a second closed end of the combustion chamber and a second piston and a center combustion space is defined between the first piston and the second piston. An air inlet assembly provides for communication of inlet air to the first combustion space, the second combustion space and the center combustion space. First, second and center injectors are provided to inject fuel into a corresponding one of the first combustion space, the second combustion space, and the center combustion space. An exhaust outlet communicates an exhaust gas flow generated in each of the first combustion space, the second combustion space and the center combustion space to a turbine section.
