The collection of dust particles in engines causes pollution, which is a major issue for manyindustries, especially for the automotive and aerospace sectors. Dust particles enter enginesthrough various channels, such as air intake systems and mechanical gaps. After entering,these particles stick to internal parts like filters, cylinders, pistons, and valves, obstructingairflow, raising friction, and hindering healthy combustion processes. Dust pollution inengines has several serious repercussions. Among the main problems are decreased power production, higher fuel consumption, less engine efficiency, and faster wear and tear of important parts.

This study investigates the surface topography of materials such as cast aluminum,aluminum, and plastic, which are commonly used as engine surfaces. In this paper, we alsoinvestigate the size of dust particles likely to be deposited on engine surfaces. These threematerials were examined using surface texture analysis based on NEWVIEWTM 9000 Zygointerferometer measurements and particle analysis provided by Digital Surf MountainLab. Tosuccessfully solve the accumulation of dust on engine surfaces, we propose using VHTenamel coating and multilayer coating. These coatings provide excellent heat resistance anddust repellence, which is critical for engine components exposed to severe environments.
