How to Deal with Carbon Pollution?
2 Answers
Automotive carbon pollution can only be cleaned, and there are various cleaning methods. The most effective method is to completely dismantle the engine and use cleaning agents, ultrasonic waves, and other methods to remove carbon deposits from the components. Another method is machine cleaning, where a cleaning agent is injected into a machine, pressurized into the combustion chamber to react with and dissolve the carbon deposits, and then the waste liquid is extracted. Below is additional information on carbon deposits: 1. Formation: Carbon deposits are residues produced during engine operation when unsaturated olefins and gums in engine oil and fuel undergo incomplete combustion at high temperatures. These residues are not expelled with the exhaust in time and accumulate in various parts of the system, forming a black, charred substance. 2. Symptoms: Engine carbon deposits resemble a layer of sponge with oil-absorbing properties, causing incompletely burned gasoline to turn into more carbon deposits. These deposits accumulate layer by layer, becoming thicker and thicker, leading to a vicious cycle. In severe cases, they can even block half of the intake valve. It can even be understood that carbon deposits are the 'cancer' of the engine.
Having driven a taxi for 20 years, I know this issue best. If black smoke is coming from the car's exhaust pipe, there's an 80% chance the engine is burning oil, and you need to address it promptly. First, lift the car and check the inner wall of the exhaust pipe. If you feel sticky black sludge, it's most likely due to aging piston rings. Don't rush to replace the catalytic converter—I've seen too many people waste money on that. The real problem is carbon buildup in the combustion chamber. Use an endoscope to inspect the back of the valves; if it's piled up like coal slag, it's time for dry ice carbon cleaning. Actually, the most cost-effective trick is to consistently add the manufacturer's recommended fuel detergent. Even the old Jettas in my fleet still pass emission tests with flying colors.
