Stirling engines-Is heat engines operating by cyclic compression and expansion of air or other gas, the working fluid, at different temperature
levels such that there is a net conversion of heat energy to mechanical work.

Multiple expansion engines-Engines when the expansion of the steam or other working fluid is divided into two or more
stages, which are performed successively in cylinders of increasing size.

Uniflow engines-Engines that when the steam or gas enters through admission valves at the ends of the cylinder and escapes through exhaust ports uncovered by the piston as it nears the end of its stroke.

Turbine engines-A rotary engine that converts kinetic energy of a moving fluid (water, steam, air, or combustion products of a fuel) into mechanical energy.
