What is the difference between a piston engine and a jet engine?
High temperature and high pressure gas from the turbine out into the tail nozzle after the jet to get thrust.
The jet engine is usually composed of a turbine tailpipes of the combustion chamber compressor, the fuel is fired and the high temperature and high pressure gas is driven to rotate the turbine, and the turbine and the compressor are consolidated so that the compressor rotates the air into the engine and pressurizes several times
Piston engine as the name suggests is fuel combustion to promote the piston movement, and then converted into crankshaft rotation, similar to the ordinary internal combustion engine.
