Fuel injectors can be cleaned using fuel injector cleaner. If they are severely clogged, the only option is to remove them for cleaning. Fuel injector cleaner: A specially designed cleaning agent for the engine fuel injection system, fuel lines, and injectors of both gasoline and diesel vehicles. Methods for cleaning fuel injectors: 1. Use in conjunction with a fuel system cleaning device; 2. Directly add to the fuel tank, with each bottle suitable for 60L—80L of fuel. It is recommended to clean every 10,000—20,000 kilometers. The functions of fuel injector cleaner are as follows: 1. Quickly removes deposits and carbon buildup from fuel injectors, intake valves, piston rings, combustion chambers, etc., restoring engine power and reducing fuel consumption; 2. Improves gasoline performance and lowers fuel consumption; 3. Resolves issues like poor uphill performance and sluggish acceleration, enhancing acceleration and restoring power; 4. Fixes problems such as unstable idling, vehicle shaking, and stalling, ensuring smooth operation; 5. Improves cold start performance; 6. Reduces noise and decreases exhaust emissions.
I usually tinker with my car, and cleaning fuel injectors is quite simple. First, turn off the engine and let it cool for half an hour, then disconnect the battery to prevent short circuits. After removing the fuel injectors, use a dedicated fuel injector cleaner to spray or a small brush to remove carbon deposits, and soak them for a few minutes. Before reinstalling, check if the sealing rings are aged, otherwise, oil leakage may occur. Start the engine immediately after cleaning to test; if it runs smoothly, you're done. It's recommended to clean them every 20,000 kilometers, and using high-quality gasoline can help prevent clogging. Don’t forget that cleaning can also save fuel and improve acceleration. DIYing gives a great sense of achievement, but don’t overlook safety.
