How to Deal with Carbon Pollution?
4 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.
Last time, it cost me nearly two thousand to deal with the carbon buildup in my dad's old Passat. Looking back now, regular maintenance would have been much better. The mechanic used a borescope to inspect the combustion chamber, and the carbon deposits on top of the pistons were shockingly thick, like a burnt pot bottom. The repair process was quite meticulous: first, disassembling the engine for an intake tract cleaning with an IV drip, then walnut blasting the valves, and finally soaking the carbon deposits with a specialized cleaning agent. The most crucial part was reprogramming the engine—the mechanic said the current ECU program could optimize the air-fuel mixture. I recommend not waiting until the check engine light comes on to address this. Adding a bottle of fuel additive after every long highway drive each year is particularly effective in preventing carbon buildup.
Tackling carbon pollution requires a two-pronged approach. Last year, I installed a Gasoline Particulate Filter (GPF) in my car, which can filter out 90% of carbon particles from the exhaust. But what really delivers immediate results is cleaning the oxygen sensor – soaking it in specialized solution for 20 minutes restores its sensitivity. Remember to do a monthly high-RPM run: for manual transmissions, drive in third gear at 4500 RPM for ten minutes; the engine's high temperature will burn off some carbon deposits. Using full synthetic oil is also crucial, especially low-ash oil with C certification, which can reduce combustion residues by 70%.
