Abstract
An alpha type Stirling engine (1) comprises an expansion cylinder (2) and a compression cylinder (3), a regenerator (4), a cooler (5), and a heater (6). Each one of the expansion cylinder (2) and the compression cylinder (3) has a movable piston (10, 11) connected to a respective linear electric generator/motor (8, 9), wherein the Stirling engine (1) further comprises a control unit (20) which is operatively connected to the linear electric generators/motors (8, 9) and which is configured to control the linear electric generators/motors (8, 9) individually so as to enable a different stroke length and/or motion profile of the piston (10) in the expansion cylinder (2) compared to the piston (11) in the compression cylinder (3).
