<p>A hot gas engine includes four groups of cylinder assemblies and a transmission output mechanism. The transmission output mechanism includes rocker-arm shaft brackets (100a, 100b), a crankshaft bracket (200), a first rocker-arm assembly (4), a second rocker-arm assembly (5), and a crankshaft (300) rotatably installed on the crankshaft bracket (200). Two crankshaft connecting rods (301a, 301b) same in length are hinged on the crankshaft (300). The first rocker-arm assembly (4) includes a first straight shaft (41), a first long arm (43) and a first short arm (44). The second rocker-arm assembly (5) includes a second straight shaft (51), a second long arm (53) and a second short arm (54). The first long arm (43) and the second long arm (53) each has two hinged parts thereon. The first short arm (44) and the second short arm (54) are hinged with two crankshaft connecting rods (301a, 301b). When the first rocker-arm assembly (4) and the second rocker-arm assembly (5) are mounted on the rocker-arm shaft brackets (100a,100b), two straight shafts (41,51) are located on the same central axis, the hinged parts of first rocker-arm assembly (4) and second rocker-arm assembly (5) are respectively situated on four corners of a square and lie in the same plane. The hot gas engine is simple in structure, low in manufacturing cost and makes less noise in operation.</p> |
