In the chemical industry, the engine is the core component that drives various equipment and processes. The optimization of its performance is of great significance for improving production efficiency and reducing energy consumption. As one of the key components of the engine, the inner wall microstructure of the cylinder liner has a profound impact on the fuel economy of the engine. This paper aims to explore how the inner wall microstructure of the chemical engine cylinder liner affects fuel economy and propose corresponding optimization strategies.The microstructure of the inner wall of the cylinder liner, including surface texture, roughness, micromorphology, etc., plays a vital role in the atomization of the fuel, the formation of the mixture and the combustion process. First of all, the smoothness of the inner wall of the cylinder liner directly affects the injection effect and atomization quality of the fuel. When the surface roughness of the inner wall of the cylinder liner is moderate, the fuel can be more evenly attached to the cylinder wall, which is conducive to the full atomization of the fuel and mixing with the air, thereby improving the combustion efficiency. On the contrary, if the inner wall of the cylinder liner is too rough or has defects, it will lead to uneven fuel injection, affect the formation of the mixture, and then reduce the combustion efficiency and increase fuel consumption.Secondly, the microstructure of the inner wall of the cylinder liner also has a significant impact on fuel economy. By adopting advanced surface treatment technology, such as laser microtexturing technology, specific micro-geometric morphologies, such as micro-cavities and micro-protrusions, can be formed on the inner wall of the cylinder liner. These microstructures can improve the lubrication performance between the cylinder liner and the piston ring, reduce friction losses, and improve the storage rate and utilization rate of fuel. For example, the use of a larger micro-cavity volume and area occupancy in the top dead center area and the main contact area of the skirt can help improve the lubricating oil storage rate and improve the lubrication performance of the cylinder-piston ring friction pair, thereby reducing engine oil consumption and fuel consumption.In addition, the microstructure of the inner wall of the cylinder liner is also closely related to the heat dissipation performance of the engine. Good heat dissipation performance helps to maintain the normal operating temperature of the engine and improve combustion efficiency. The microstructure of the inner wall of the cylinder liner can optimize the flow path and heat dissipation area of the coolant, thereby improving the heat dissipation efficiency of the engine. When the engine temperature is too high, the evaporation and combustion process of the fuel will be affected, resulting in a decrease in fuel economy. Therefore, by optimizing the microstructure of the inner wall of the cylinder liner, the heat dissipation performance of the engine can be improved, thereby improving fuel economy.In summary, the microstructure of the inner wall of the chemical engine cylinder liner has an important impact on fuel economy. In order to optimize fuel economy, the following strategies can be adopted: first, the roughness and micromorphology of the inner wall of the cylinder liner can be controlled through precision machining and surface treatment technology; second, advanced laser microtexturing technology can be used to form a microstructure on the inner wall of the cylinder liner that is conducive to fuel atomization and lubrication; third, the heat dissipation design of the cylinder liner can be optimized to improve the heat dissipation efficiency of the engine. The implementation of these measures will help reduce the fuel consumption of chemical engines, improve energy utilization efficiency, and contribute to the sustainable development of the chemical industry.
