Embodiment Construction

[0016] The present invention is described below in conjunction with accompanying drawing.

[0017] as attached Figure 1-2 The shown piston of the present invention includes a piston body 1, and a ring-shaped cooling device 2 is arranged inside the piston body 1; at least two circular holes 3 are opened on the upper end surface of the piston body 1; The round holes 3 are equidistantly arranged on the same circumference; the round holes 3 are adjacent to the cooling device 2; the lubricating liquid 4 which is condensed into a solid state is installed in each of the round holes 3; the circumferential surface of the piston body 1 There is an oil outlet hole 5 communicating with each round hole 3; a rubber plug 6 is provided at the port of each round hole 3; the number of the three round holes is four.

[0018] During use, the lubricating liquid 4 is first condensed into a solid state and packed into the round hole 3, plugged with a rubber plug 6, and the annular cooling device 2...

Abstract

The invention discloses a piston which comprises a piston body. An annular cooling device is arranged inside the piston body. At least two circular holes are formed in the upper end face of the piston body. The circular holes are arranged on the same circumference at equal intervals. The circular holes are adjacent to the cooling device. Lubricating liquid condensed to a solid state is arranged inside each circular hole. Oil outlet holes communicated with the circular holes are formed in the circumference face of the piston body. A rubber plug is arranged at a port of each circular hole. The number of the circular holes is four. The piston is capable of timely diffusing the quantity of heat generated by contact with high-temperature gas and capable of effectively decreasing abrasion. The service life of the piston is much longer than that of an existing piston.

Description

technical field [0001] The invention relates to a piston, in particular to a piston suitable for an internal combustion engine, and belongs to the technical field of mechanical parts. Background technique [0002] The piston is a mechanical part that reciprocates along the cylinder axis in a mechanical cylinder such as a reciprocating piston internal combustion engine. [0003] The piston works under the conditions of high temperature, high pressure, high speed and poor lubrication. [0004] The piston is directly in contact with high-temperature gas, and the instantaneous temperature can reach more than 2500K. Therefore, the heat is severe, and the heat dissipation condition is poor, so the temperature of the piston is very high when it is working, and the top is as high as 600-700K, and the temperature distribution is very uneven; the top of the piston bears The gas pressure is very high, especially the power stroke pressure is the largest, which makes the piston produce ...
