Problems solved by technology
The cylinder liner support surface of the existing engine is at its top part, and it is the minimum distance between the outer circle of the support surface and the cylinder block bolt that limits the maximum diameter of the cylinder liner. Due to the limitation of the distance, the power of the existing engine is limited. It cannot realize the large power demand of small size and large power required by people

Embodiment Construction
[0013] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.
[0014] Such as figure 1 For the comparison of the original structure diagram, figure 2 The cylinder of the best embodiment shown in the present invention has a cylinder liner 1 and a cylinder body 2. The outer ring of the cylinder liner 1 has a supporting platform 11, and the inner ring of the cylinder body 2 has a protrusion 21 supporting the supporting platform 11. The cylinder liner 1 and the cylinder body 2 are provided with a water sealing ring 4, the supporting platform 11 is arranged at the middle and lower end of the cylinder liner 1, and the protrusion 21 corresponding to the supporting platform 11 is arranged at the middle and lower part of the inn...

The invention relates to the technical field of cylinders, in particular to an expended and power increased cylinder of a diesel engine, which is provided with a cylinder sleeve and a cylinder body, wherein the outer cycle of the cylinder sleeve is provided with a supporting mesa; the inner cycle of the cylinder body is provided with a protrusion supporting the supporting mesa; a water sealing ring is arranged in the connected position of the cylinder sleeve and the cylinder body; the supporting mesa is arranged in the middle lower end of the cylinder sleeve; the protrusion corresponding to the supporting mesa is arranged in the middle lower part of the inner cycle of the cylinder body; the water sealing ring is fixed in the connected position of the cylinder sleeve and the upper end of the cylinder body; and a cylinder sleeve spacer is arranged between the supporting mesa and the supporting protrusion. The invention has the advantages that the cylinder is expanded so that the engine has higher power in the conditions with same volume and weight, which saves space and cost; and the invention enables cylinder cover bolts to be arranged compactly so that the design of lightweight and high compatibilization of the whole engine is realized.
Description
technical field [0001] The invention relates to the field of cylinders, in particular to a cylinder of a diesel engine whose power is increased by expanding the cylinder. Background technique [0002] A cylinder is a cylindrical metal part that guides a piston in a linear reciprocating motion. The working fluid converts heat energy into mechanical energy through expansion in the cylinder of the diesel engine; the gas is compressed by the piston in the cylinder of the compressor to increase the pressure. The cylinder converts the pressure energy of compressed air into mechanical energy, and the driving mechanism makes linear reciprocating, swinging and rotating motions. [0003] The cylinder has a cylinder liner and a cylinder block, and the inner diameter of the cylinder represents the output force of the cylinder. The cylinder liner support surface of the existing engine is at its top part, and it is the minimum distance between the outer circle of the support surface and...
