A low -entropy mixed-combustion turbo compound explosive engine includes an intake passage (1), an exhaust passage (2), an explosive engine (3), a turbo-compressor (4) and a power turbine (5). A gas inlet of the turbo-compressor (4) is communicated with a low-pressure gas source (6) and a compressed gas outlet of the turbo-compressor (4) is communicated with the intake passage (1). The intake passage (1) is communicated with a combustion chamber (301) of the explosive engine (3) by an intake valve (7) and the combustion chamber (301) is communicated with the exhaust passage (2) by an exhaust valve (8). The exhaust passage (2) is communicated with a gas medium inlet of the power turbine (5). The gas pressure at the compressed gas outlet of the turbo-compressor (4) is equal to or higher than the gas pressure in a cylinder at the end of a compression stroke of a conventional internal combustion engine. The explosive engine (3) does not output power to the turbo-compressor (4), while the power turbine (5) outputs power to the turbo-compressor (4). The engine realizes high efficiency and low pollution, and improves environment-friendly performance.
