Abstract

The invention discloses a T-shaped piston on a general gasoline machine. The T-shaped piston comprises a piston body which is integrally in a T shape, the piston body comprises a head portion and a skirt portion, the head portion comprises a piston ring, the top surface of the piston ring is of a flat top structure, the periphery of the piston ring is provided with at least two circular grooves which are parallelly distributed at intervals in the axial direction, the thickness of each circular groove is 1 mm, the skirt portion comprises a front arc surface, a left straight surface, a reverse arc surface and a right straight surface which are connected end to end to form a frame-shaped structure, the left straight surface and the right straight surface are provided with a left pin shaft sleeve tube and a right pin shaft sleeve tube correspondingly, the left pin shaft sleeve tube and the right pin shaft sleeve tube are designed coaxially, the front arc surface is provided with an oil return hole which is formed by integral pressure casting, and the outer walls of the front arc surface and the reverse arc surface are matched with the outer wall of the piston ring correspondingly. By means of the T-shaped piston on the general gasoline machine, the friction force is reduced, and the service life is prolonged.

Description

technical field [0001] The invention relates to a T-shaped piston on a general-purpose gasoline engine. Background technique [0002] The piston on the gasoline engine is traditionally round, such as figure 1 , figure 2 , image 3 As shown, the joint surface with the engine cylinder is all-round contact and full friction, with high resistance, high heat, and low power; the first and second air ring grooves of the traditional piston are both 1.5mm thick, with high frictional resistance and poor sealing; The traditional piston adopts a pit structure, which is easy to form a dead angle with CH in the combustion, resulting in bad discharge; the traditional piston oil return hole adopts secondary processing, with a 1.0mm drill bit to drill 12 holes, the process is cumbersome and backward, and the cost is high. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a T-shaped piston on a general-purpose gasoline engine, w...
