The anti-eccentric wearing device solves the problems of high processing difficulty, easy wearing, high energy consumption and the like existing in the internal combustion engine at present. Upper shaft sleeves of the anti-eccentric wearing device for the cylinder of the internal combustion engine are fixed at the lower ends of cylinder holes of a cylinder block, and lower shaft sleeves of the anti-eccentric wearing device are fixed at the inner bottom of a lubricating oil tank; two ends of each piston guide rod are respectively connected to the corresponding upper shaft sleeve and the corresponding lower shaft sleeve in a sleeved manner; each connecting rod is connected to the corresponding piston guide rod through a piston guide rod retaining latch sleeve; the piston guide rod retaining latch sleeves and the piston guide rods are fixed by pin bolts; and the upper ends of the piston guide rods and pistons are fixed. The anti-eccentric wearing device is simple in structure, easy to process, and convenient to install, is energy-saving, and can greatly prolong the service life of the cylinder and the piston.

Description

Technical field [0001] The invention relates to the field of internal combustion engines, in particular to an anti-eccentric wear device for cylinders of internal combustion engines. Background technique [0002] At present, the piston in the cylinder of an internal combustion engine moves linearly in the cylinder, but the power provided by the linear motion of the piston pushes the crankshaft connecting rod to operate with a special structure, and the direction of thrust or pulling force generated by the piston on the crankshaft connecting rod changes constantly That is to say, the direction of the thrust or pulling force of the piston on the crankshaft connecting rod is not kept in the same straight line with the direction of piston movement. Therefore, the friction force generated by the piston on the cylinder wall is not uniform when the piston is running in the cylinder. After the piston moves at a high speed for a long time in the cylinder, it is easy to cause eccentric wea...

AI Technical Summary

Problems solved by technology

[0002] At present, the piston in the cylinder of the internal combustion engine moves in a straight line in the cylinder, but the power provided by the linear motion of the piston drives the special structure of the crankshaft and connecting rod to run, and the direction of the thrust or pulling force generated by the piston when it moves to the crankshaft and connecting rod is constantly changing. That is to say, the direction of the thrust or pull force of the piston on the crankshaft connecting rod is not kept on the same line as the direction of the piston movement, so the friction force generated by the piston on the cylinder wall when it is running in the cylinder is uneven, so After the piston moves at a high speed for a long time in the cylinder, it is easy to cause eccentric wear, which will damage the inner wall of the cylinder or the piston and cause air leakage, resulting in a decrease in the utilization rate of heat energy of the internal combustion engine. This is a problem that has not been solved since the use of the internal combustion engine.

In addition, the piston also plays a guiding role in the movement of the cylinder. In order to prevent the eccentric wear of the cylinder, the length of the piston is appropriately increased. However, increasing the length of the piston increases the weight of the piston, which will inevitably lead to the consumption of the piston itself. more energy resulting in waste of fuel
