The utility model discloses a novel piston top combustor which comprises an omega-shaped combustor body. The combustor body comprises a throat opening and a bottom. The throat opening is vertically formed relative to the bottom. A boss is arranged in the center of the bottom. The included angle alpha of the two sides of the boss is 90 degrees. The lateral deviation distance C1 of a center line of the combustor body relative to a center line of a piston is 1.79 mm, and the vertical deviation distance C2 is 5.33 mm. The technical problem of cylinder sticking is solved by changing the lateral and vertical deviation distances of the center line of the combustor body relative to the center of the piston, the combustor body is designed and improved fast, and cost is low. The problems of cylinder sticking and fusing are solved, a simple solving method is provided for the problem of cylinder sticking at the same time, and therefore expenditure is saved.
