[0002] Power equipment is a machine that converts energy (such as fuel, electricity, wind power, etc.) into mechanical energy to drive machines, tools, vehicles and other equipment. They are widely used in various industries, such as transportation, industrial production, energy production, etc. Among them, internal combustion power equipment uses fuel (such as gasoline, diesel, etc.) mixed with air to burn, and the heat energy generated is converted into power through mechanical transmission.

[0003] Common internal combustion power equipment includes engines, etc. In order to extend the service life of power equipment, lubricants and other blending agents are often applied to reduce the wear of the power equipment during use. Some components in the lubricant may evaporate at high temperatures, resulting in a reduction in oil volume; in low temperature environments, the viscosity of the lubricant increases, the fluidity deteriorates, and there may be a risk of insufficient lubrication during startup. These problems will lead to a steady decline in the lubricant and increase the degree of wear of the power equipment during operation. Therefore, ensuring the stability of the blending agent is crucial to the service life and use effect of the power equipment. How to improve the stability of the blending agent has become a technical problem that needs to be solved urgently. Summary of the invention
