Abstract

The utility model provides an annular engine which comprises a cylinder set and a gear set. The cylinder set comprises two connecting arms and four arc-shaped components, and the four arc-shaped components are connected end to end through the way that arc-shaped pistons are matched with arc-shaped cylinders to form an annular structure. The two ends of each connecting arm are fixedly connected with two opposite arc-shaped components respectively. The gear set comprises a first gear, a second gear and a third gear, wherein the first gear, the second gear and the third gear are the same in tooth number and in rotation direction and are meshed with racks in sequence. The included angle of the connecting line of the centers of the circles of adjacent gears and the connecting line of the midpoints of the connecting arms is 60 degrees, and a gear shaft of the first gear or a gear shaft of the second gear or a gear shaft of the third gear is an output shaft. According to the annular engine, due to the fact that a crankshaft is not arranged, the thrust direction of fuel gas to the pistons is always perpendicular to the rotation radii of the pistons, and thus the heat-work conversion rate of the engine is improved; the four arc-shaped components are distributed symmetrically, excellent dynamic balance is achieved, and high-speed running can be achieved conveniently.
