Abstract: The present disclosure relates to an engine (100) including a cylinder (102) that is filled with carbon dioxide. A first piston (104) is slidably configured inside the cylinder (102) and being configured to form a first cylinder (108) with a first end (130) of the cylinder (102). A second piston (106) is slidably configured inside the cylinder (102) and being configured to form a second cylinder (110) with a second end (132) of the cylinder (102). A heater (112) is circumferentially disposed around the first cylinder (108) and the first piston (104) is configured to expand a hot carbon dioxide received inside the first cylinder (108) from the heater (112). A cooler (116) is circumferentially disposed around the second cylinder (110) and second piston (104) is configured to compress a cold carbon dioxide received inside the second cylinder (110) from the cooler (116).
