How to Remove Carbon Deposits from the Engine?

Engine carbon deposit removal methods include: 1. Cleaning the throttle valve: Remove the engine cover, take off the throttle valve, clean it with carburetor cleaner, dry it with a cotton cloth, and reinstall it. 2. Cleaning carbon deposits in the intake system: Purchase a bottle of intake system cleaner, pour it into the storage tank of a specialized cleaning device, connect it to the intake system, and start the engine to use vacuum to draw the cleaner into the intake passages for cleaning purposes. An engine is a machine capable of converting other forms of energy into mechanical energy, applicable both as a power generation device and as the entire machine including the power unit. Types include internal combustion engines, external combustion engines, and electric motors.

As a veteran driver with over a decade of experience, I've found that engine carbon buildup is mainly caused by prolonged low-speed driving or poor fuel quality. I usually use fuel additives to address this issue – many brands like 3M or Red Line on the market work quite well. Adding one can to the fuel tank followed by a long-distance drive can effectively clean it. During routine maintenance, I also recommend avoiding prolonged idling and suggesting more high-RPM driving to let the engine self-clean. For severe carbon buildup, such as when the car shakes or fuel consumption increases, it's necessary to consider removing and cleaning the fuel injectors and intake system. For prevention, I always use high-octane gasoline from reputable gas stations, which helps reduce carbon accumulation. In short, untreated carbon buildup can affect power and emissions, so regular use of additives is the most worry-free solution.

Over the past few years while helping friends with car repairs, I've frequently encountered engine carbon buildup issues, mostly caused by vehicles frequently driving in congested city traffic. For manual carbon cleaning, I first open the hood to check if there's oil residue on the throttle body - if present, I spray it with cleaner. Then I remove the spark plugs to clean internal carbon deposits using specialized tools. This job is best done in a garage with all necessary tools prepared, like gloves and cleaning brushes. For severe carbon buildup, walnut shell blasting might be needed, but that's a more professional service. Prevention is crucial - I recommend owners add fuel additive every 2,000-3,000 km to dissolve carbon deposits in advance and prevent engine issues. Proper carbon cleaning not only improves performance but also extends engine lifespan.

When I first bought my car, I had no idea what carbon deposits were. It wasn’t until the engine started making strange noises that I found out. Now I’ve learned my lesson—the simplest method is to drive more on the highway. I regularly push the speed above 100 km/h for half an hour to burn off some carbon buildup. If that doesn’t work, I use fuel additives; even the cheap ones from gas stations will do. Just pour them into the fuel tank to mix with the gasoline for natural cleaning. One thing to note: don’t overuse additives or frequently rev the engine too high, as it can damage the engine. During routine maintenance, I ask the mechanic to check the spark plugs and intake components and address any issues promptly. Carbon deposits not only waste fuel but also pollute the environment, so I advise new drivers to prevent them through good driving habits, like avoiding frequent short-distance starts and stops. Overall, this approach is both cost-effective and safe.
