Internal combustion engine connecting rod piston assembly and combustion chamber comprising same

Abstract

The invention discloses an internal combustion engine connecting rod piston assembly and a combustion chamber comprising the same. The internal combustion engine connecting rod piston assembly comprises two connecting rods, a piston provided with a piston head and a piston skirt, and big bearing bushes, wherein a small head end of each of the two connecting rods is sleeved with a small bearing bush in a matching manner to be connected with a T-shaped piston pin; the piston pin is connected with the piston skirt and the piston head in sequence respectively through a piston connecting piece to be relatively connected with the other end of each of the two connecting rods; the piston pin is connected with the piston head through a spherical hinge; the big head end of each of the two connecting rods is sleeved with a big bearing bush in a matching manner. The combustion chamber comprises a piston connecting rod structure and the internal combustion engine connecting rod piston assembly. Through the adoption of the internal combustion engine connecting rod piston assembly and the combustion chamber, the integral processing difficulty of the piston can be effectively reduced; the piston is divided into the piston head and the piston skirt to assemble to enable heat quantity of the piston head to be directly taken away by piston coolant oil, so that heat quantity transmitted to the piston skirt is greatly reduced to enable the piston skirt to have less deformation, and the NVH performance of the internal combustion engine is improved to a certain extent.

Description

technical field [0001] The invention relates to the technical field of an internal combustion engine, in particular to a connecting rod piston assembly of an internal combustion engine and a combustion chamber including the connecting rod piston assembly. Background technique [0002] The piston connecting rod was born with the internal combustion engine. The function of the piston connecting rod is: the piston bears the gas pressure in the cylinder, and transmits this force to the connecting rod through the piston pin to drive the crankshaft to rotate, thereby converting chemical energy into mechanical energy. With the development of internal combustion engines, the power density is required to be higher and higher, so the explosion pressure of internal combustion engines has been greatly improved. Conventional piston connecting rod materials and structures can no longer meet the requirements of some internal combustion engines. Long-term use will not only cause problems su...
