What is Dry Ice Carbon Deposit Removal?
2 Answers
Dry ice cleaning technology is a new cold spray technique that utilizes the high-pressure air from an air compressor to blast dry ice onto engine carbon deposits. The accelerated impact of dry ice particles causes the carbon deposits to crack, while the extreme low temperature of dry ice freezes and embrittles the deposits, reducing their adhesion. This rapidly freezes and completely strips away dirt and oil contaminants from the surface. The advantages of dry ice carbon cleaning are as follows: 1. It causes no damage to the metal surfaces of the engine; 2. It does not affect the engine's sealing performance; 3. It enables thorough carbon cleaning without engine disassembly, achieving rapid and effective results.
Dry ice carbon cleaning is an automotive cleaning technique. Having driven for over a decade, I've used this method several times and found it quite reliable. Dry ice is essentially frozen carbon dioxide in small solid particles. When sprayed into the engine, it instantly sublimates into gas, generating tremendous impact force that knocks off carbon deposits. Carbon buildup refers to hardened residues left after fuel combustion, clogging pistons or cylinder walls, causing engine vibration and increased fuel consumption. Dry ice cleaning requires no disassembly, leaves no chemical residue as it's a physical method, delivers lasting effects, and completes within half an hour – my car's acceleration and idle issues were both resolved. Compared to traditional cleaners, it's safer and more eco-friendly, though I recommend professional shops handle it since dry ice's extreme cold (-78.5°C) risks frostbite during DIY attempts. Overall, this proves highly effective for routine driving maintenance.
