[LaJuliette]

Methods to remove engine carbon deposits include: 1. Adding fuel cleaner to the fuel tank; 2. Using a liquid supply device for cleaning; 3. Disassembling the engine for cleaning. Ways to reduce carbon deposits in the engine are: 1. Minimizing short-distance cold engine driving; 2. Avoiding low-speed high-gear driving with manual transmission; 3. Using gasoline that matches the engine's compression ratio; 4. Using engine oil with the viscosity recommended by the manufacturer; 5. Using high-quality fuel. The reasons for engine carbon deposits are: 1. Incomplete combustion of engine fuel; 2. Oxidation and polymerization of unstable components like olefins in gasoline under high temperatures; 3. Frequent low-speed and idling conditions of the vehicle.
