Abstract

A Stirling engine comprising: a crank case (1) with a crank shaft (2) arranged therein, a displacer cylinder (3) with a reciprocatingly arranged displacer piston (4) therein, said displacer piston (4) being connected to said crank shaft (2) via a connecting rod (5) extending through a first end of said displacer cylinder (3), and wherein the displacer cylinder (3) defines a hot chamber (6) and a cool chamber (7) separated by the displacer piston (4), a working cylinder (8) with a reciprocatingly arranged working piston (9) therein, said working piston (9) being connected to said crank shaft (2) via a connecting rod (10) extending through a first end of the working cylinder (8), a heater device comprising a combustion chamber (15) arranged at a second end of said displacer cylinder (3) opposite to said first end, a first heat exchanger (16) and a second heat exchanger (17), said first heat exchanger (16) comprising at least one tube (18) that extends from a head (19) of the displacer cylinder (3) provided at said second end of the displacer cylinder (3) into the combustion chamber (15) and out of the combustion chamber (15) to the second heat exchanger (17), which is comprised by a regenerator provided outside the combustion chamber (15) and outside the displacer cylinder (3), and wherein the hot chamber defined by the displacer cylinder (3) is in fluid communication with a second end of the working cylinder through the first and second heat exchangers, wherein the combustion chamber (15) is defined by a tubular wall element, and has a first end which is connected to the displacer cylinder (3) and a second end which is remote from the displacer cylinder (3), and a burner arrangement for generating a flame inside the combustion chamber (15). The Stirling engine comprises an exhaust gas catalyst element which is arranged inside the combustion chamber (15).
