A split-cycle engine (4), comprising a compression cylinder (10) having a first volume (12) for a first working fluid and a second volume (14) for a second working fluid, the first volume and second volume being separated by the compression piston (20), an expansion cylinder (50) having a first volume (52) for the first working fluid and a second volume (54) for the second working fluid, the first volume and second volume being separated by the expansion piston (60), and a fluid coupling (90) between the second volume 14 of the compression cylinder (10) and the second volume (54) of the expansion cylinder (50), wherein the two second volumes (14, 54) and the fluid coupling (90) provide a closed volume for the second working fluid, wherein the fluid coupling (90) comprises a regenerator (92) arranged such that the two second volumes (14, 54) are thermally decoupled

Split cycle engine

The invention discloses a Stirling type hot gas self cooling system which comprises a hot gas passageway, a Stirling engine and a Stirling cryocooler The hot gas passageway respectively penetrates a hot cylinder of the Stirling engine and a cooling cylinder of the Stirling cryocooler The Stirling engine outputs power to the Stirling cryocooler The Stirling engine and the Stirling cryocooler are driven to operate by heat quantity of hot gas to achieve the purpose of reducing temperature of the hot gas The Stirling type hot gas self cooling system has the advantages of being simple in structure and good in cooling effect

Stirling type hot gas self cooling system

The method involves providing an explosion engine and a hot air engine (14), and loading an operating gas heater of the hot air engine with dissipated heat of exhaust gas of an internal-combustion engine (1) for producing torque. The hot air engine is operated according to a stirling engine principle, where the hot air engine forms an unit as an auxiliary engine of the internal-combustion engine.
