In which heat engine a jet of steam or gas heated to a high temperature rotates the engine shaft in the absence of a connecting rod piston and a crankshaft?

There are the following types of engines:

steam;
internal combustion;
gas;
reactive.

It should be noted that today another type of engine is used. In which heated air rotates the motor shaft without any assistance. This type of turbine is common in power plants.
Of greatest importance is the use of heat engines in thermal power plants, where they drive the rotors of generators of electric current.
