Problems solved by technology
The large amount of deformation of the cylinder liner will lead to poor sealing of the piston ring, and the engine oil will easily escape into the combustion chamber to produce particles, resulting in poor particle emission levels; and the gas from the combustion chamber will easily enter the crankcase, and the leakage of working gas will lead to unsatisfactory fuel consumption. ; And the large deformation of the cylinder liner will lead to increased consumption of lubricating oil, wear of the cylinder liner and other consequences

Embodiment Construction
[0015] Below the present invention will be further described in conjunction with the embodiment in the accompanying drawing:
[0016] Such as figure 1 As shown, the present invention mainly includes a cylinder liner 1 and a cylinder block 2, the cylinder liner 1 is located in the cylinder block 2, and the cylinder liner 1 and the cylinder block 2 are coaxially connected. The bore of cylinder liner 1 is: 85-100mm, and the height is: 160-200mm. Cylinder block 2 is made of HT250 material
[0017] Such as figure 2 As shown, cylinder liner upper shoulder 1.1 is provided on the outside of the upper part of cylinder liner 1, cylinder block upper support shoulder 2.1 is provided on the inner side of the upper part of cylinder block 2, and cylinder liner upper shoulder 1.1 is located on cylinder block upper support shoulder 2.1, and the two are closely matched Form the upper support. A first sealing ring 3 is provided between the upper shaft shoulder 1.1 of the cylinder liner and ...

The invention relates to a supporting mechanism of a wet-type cylinder sleeve and belongs to the technical filed of mechanical structures. Particularly, the supporting mechanism is used for supporting each part of the wet-type cylinder sleeve. The supporting mechanism comprises the cylinder sleeve and a cylinder body. A cylinder sleeve upper shaft shoulder is located on the outer side of the upper portion of the cylinder sleeve. A cylinder body upper supporting shoulder is arranged on the inner side of the upper portion of the cylinder body. The cylinder sleeve upper shaft shoulder is located on the cylinder body upper supporting shoulder to form upper portion supporting in a tight fit mode. A cylinder sleeve lower shaft shoulder is arranged on the outer side of the lower portion of the cylinder sleeve, and a cylinder body lower supporting shoulder is arranged on the inner side of the lower portion of the cylinder body. The cylinder sleeve lower shaft shoulder is arranged on the cylinder body lower supporting shoulder to form lower portion supporting in a tight fit mode. The supporting mechanism of the wet-type cylinder sleeve is ingenuous in structure, reliable and reasonable and effectively reduces the phenomena that the middle part of the cylinder sleeve deforms dynamically due to swelling caused by high temperature and high pressure and the cylinder sleeve deforms statically due to manual installation. Stability of the cylinder sleeve and other parts of a diesel engine in the process of working is improved. Service life of the parts is prolonged.
Description
technical field [0001] The invention relates to a support mechanism for a wet cylinder liner, specifically for supporting various parts of a wet cylinder liner, and belongs to the technical field of mechanical structures. Background technique [0002] With the development of internal combustion engine technology, the degree of strengthening of diesel engines is getting higher and higher, and the economic requirements and emission indicators are becoming more and more stringent. The cylinder liner is an important motion pair when the diesel engine is working, and it is an important part of the internal combustion engine. Its deformation determines the service life of the internal combustion engine to a large extent, and directly affects the work and emission performance of the internal combustion engine. [0003] The traditional wet cylinder liner support mechanism is a structure of upper support plus lower support. When the diesel engine is working, the piston ring and the...
