Methods to clean carbon deposits in a car include: 1. Adding fuel additives when refueling; 2. Engine disassembly cleaning; 3. Using a car drip cleaning method. The main components of carbon deposits in a car are: 1. Metal debris generated from engine friction and wear; 2. Dust from the air; 3. Sticky substances formed by the oxidation, thickening, and acidification of engine oil under high temperatures; 4. Paint films produced by the oxidation and concentration of lubricating oil. The effects of increased carbon deposits in a car are: 1. Difficulty in starting; 2. Insufficient horsepower, unstable acceleration, and shaking; 3. Air-fuel ratio imbalance; 4. Failure to meet emission standards; 5. Reduced combustion efficiency. Methods to prevent carbon deposits in a car include: 1. Waiting for 1 minute or 30 seconds before turning off the engine after reaching the destination; 2. Increasing shift RPM for manual transmission cars.
I've got plenty of experience dealing with carbon deposits in cars. Back when I first started driving, I often felt the throttle was sluggish and fuel consumption suddenly increased - turned out to be carbon buildup. Now I regularly add quality fuel system cleaners and deliberately rev higher on highways to flush it out. For places like the throttle body, it's not difficult to DIY clean with some spray cleaner bought online. But for stubborn carbon deposits inside the engine, you'll need professionals with walnut shell blasting equipment. Just last week I had it done at the shop - the mechanic said my 80,000km car produced half a bowl of black residue. Always remember not to cheap out on fuel - low-quality gasoline tends to leave more gummy deposits. Letting the engine idle for two minutes before shutting off also helps reduce carbon buildup.
