Stirling engine alpha type
An alpha type Stirling engine (or two piston engine) has a structure quite different from a beta or gamma Stirling engine. The basic principle of operation is similar to the previous ones, but it's better to explain it individually to avoid confusion, since the phases are not equal.
An alpha type Stirling engine requires necessarily a regenerator, which separates the hot and cold sources, and also have the ability to store energy.
The main feature of this engine is that there is no difference between labor and the piston displacement. In fact, consists of two pistons undifferentiated, each in its cylinder (cold and hot), maintaining the tight gas. The gas is communicated through the regenerator and the movement of the pistons is also due to the binding of the respective connecting rods to the crankshaft. The movement of a piston over the other also differs by 90 °.
