Does the Engine Need Carbon Deposit Cleaning?

[AlyssaDella]

Engine carbon deposit cleaning is necessary. The faults caused by engine carbon deposits: 1. Combustion chamber carbon deposits: Can lead to engine knocking; 2. Fuel injector carbon deposits: May cause engine shaking and poor acceleration; 3. Throttle body carbon deposits: Can result in weak vehicle acceleration and unstable idle speed, making it difficult to start. Methods for cleaning engine carbon deposits: 1. Install a three-way catalytic converter in the vehicle's exhaust system at the bottom, primarily to reduce exhaust pollutants emitted by the engine; 2. Pour a bottle of engine internal cleaner into the engine oil, then idle the engine for 30 minutes to clean before draining the old oil, replacing the oil filter and adding new engine oil; 3. Remove the engine cover, take off the throttle body, use a cleaner to remove carbon deposits and other stains inside the throttle body and on the flap valve, then dry with a cotton cloth.

A veteran driver with over 20 years of experience talks about carbon deposits: Engines do require regular carbon cleaning as deposits gradually clog fuel injectors and intake valves, making acceleration sluggish and fuel consumption skyrocket. I've personally experienced this – around every 20,000 kilometers, the engine starts shaking noticeably with muffled sounds, especially lacking power when climbing hills. A professional cleaning costing about 400-500 yuan makes an immediate difference. Always refuel at reputable gas stations and occasionally add a fuel system cleaner to prevent issues. Remember, unaddressed carbon buildup can eventually damage piston rings, leading to repairs costing tens of thousands – far more expensive than preventive maintenance.

As a DIY car repair enthusiast, I believe carbon deposit cleaning can sometimes be done by yourself. Just buy a reliable fuel system cleaner, pour it into the fuel tank, and take a highway drive to remove some carbon deposits - it's cost-effective and convenient. I've tried it twice, and indeed noticed some engine power recovery and slight fuel consumption reduction. But be careful not to buy cheap counterfeit products that might corrode sensors. For severe carbon buildup issues like hard starting or strong exhaust odor, it's better to visit a repair shop for high-pressure cleaning - more worry-free and safer. Regular inspection is key; don't wait until the engine breaks down to regret it.

From an environmental perspective, cleaning carbon deposits in the engine is quite important. Carbon buildup can lead to incomplete combustion, resulting in more harmful exhaust emissions that pollute the air. I believe reducing emissions while driving benefits the planet. Simple cleaning methods, such as using fuel additives or regular maintenance, not only optimize engine efficiency but also minimize environmental impact. Additionally, prevention is key—using high-quality gasoline and avoiding air conditioning use in traffic jams can help reduce carbon deposit formation, ensuring longer-term protection for nature.
