The engine assembly of claim 5, wherein said eccentric compression chamber and said chute compression chamber are not in sealed communication with each other, and wherein said eccentric compression chamber is compressed with gas and said chute compression chamber is compressed with liquid; the temperature of the mixing chamber is raised by combustion in the combustion chamber, high-pressure liquid formed by compression of the eccentric cavity enters the heat exchanger to absorb heat to form high-temperature high-pressure liquid, and the high-temperature high-pressure liquid enters the mixing chamber to absorb heat to form liquid vapor and is mixed with gas entering the mixing chamber from the combustion chamber to form high-temperature high-pressure mixed gas.
7. The engine device according to claim 6, wherein the expander comprises an expansion cylinder and an expansion rotor eccentrically arranged in the expansion cylinder, the expansion rotor is provided with an expansion chute, an expansion sliding block is slidably connected in the expansion chute, and the expansion rotor rotates to drive the expansion sliding block to be always attached to the inner wall of the expansion cylinder; the inner wall of the expansion cylinder, the expansion rotor and the expansion sliding groove are enclosed to form an expansion eccentric cavity, and the expansion sliding groove of the expansion cylinder and the expansion sliding block are enclosed to form an expansion sliding groove cavity.
8. The engine device as claimed in claim 7, wherein the expansion cylinder extends outwards to form a nozzle, the nozzle is provided with an inclined opening at one end inside the expansion cylinder, the mixing chamber is communicated with the expansion eccentric cavity through the nozzle, the high-temperature and high-pressure mixed gas in the mixing chamber enters the expansion eccentric cavity to push the expansion slide block to rotate, and the expansion slide block drives the expansion rotor to rotate; the expansion rotor is in transmission connection with the compression rotor, and the expansion rotor drives the compression rotor to rotate to compress gas and liquid; the compressor, the combustor and the expander form a power cycle.
9. The engine assembly of claim 8, wherein the expansion cylinder is further in communication with a cooling tank, the cooling tank having a cooling tube disposed therein, the cooling tube having an inlet in communication with a fluid reservoir and an outlet in communication with the compression chute chamber, the fluid reservoir being further in communication with the cooling tank; the high-temperature high-pressure mixed gas is expanded by the expander to form high-temperature low-pressure mixed gas, the high-temperature low-pressure mixed gas enters the cooling box and is cooled by the cooling pipe to form low-temperature low-pressure mixed gas, and liquid steam in the low-temperature low-pressure mixed gas is condensed to form condensed liquid which flows into the liquid box.
10. An engine assembly according to any one of claims 6 to 9 wherein a resilient member is connected between the compression cylinder and the compression slide or between the expansion cylinder and the expansion slide.
