Problems solved by technology

[0002] The friction between the existing engine piston and cylinder is mostly sliding friction. The structure of the engine is cylinder, piston, seal, etc. The piston is arranged in the cylinder, the seal seals liquid or gas or solid, and the cylinder supports the piston through the seal. , the piston reciprocates in the cylinder under the support of the seal, and a large sliding friction resistance is formed between the seal, the piston and the cylinder. Due to the large friction resistance, when the seal is seriously damaged, it will not be able to continue to work, resulting in Suspension losses, and even serious safety accidents
In addition, the relative movement between the piston and the cylinder needs to overcome a large sliding friction force. When the volume and weight of the piston are large and the cavity of the cylinder is large, the wear on the cylinder is more serious due to the large volume and weight of the piston. The sliding friction resistance between the piston and the cylinder seriously affects the movement speed of the piston, which reduces the working efficiency and increases the energy consumption
For how to reduce the sliding friction between the piston and the cylinder, the commonly used method is to improve the machining accuracy of the cylinder and the piston, improve the surface roughness of the cylinder and the piston, and reduce the sliding friction resistance of relative motion. However, It does not fundamentally change the structure of the reciprocating motion of the cylinder and the piston by sliding friction, so the effect is not obvious
