How often should carbon deposits be cleaned for the third-generation EA888?
1 Answers
The third-generation EA888 should have carbon deposits cleaned every 30,000 kilometers if frequently driven on highways, and every 15,000 kilometers if not. 4S shops typically recommend maintenance every 10,000 kilometers, but drivers can adjust based on their driving conditions. For those who frequently drive on highways, the interval can be extended to 30,000-40,000 kilometers, while others can clean carbon deposits every 20,000-30,000 kilometers. Relevant information about carbon deposits is as follows: Hazards of cylinder carbon deposits: Excessive carbon deposits can alter the engine's original structural parameters, reduce engine power, and increase fuel consumption. In severe cases, it may cause engine knocking, abnormal acceleration noises, and damage to pistons and crankshafts. Carbon deposits accumulate layer by layer, becoming increasingly thicker, leading to a vicious cycle. In extreme cases, intake valves may become half-blocked, ultimately resulting in engine oil burning and necessitating major repairs. Methods for cleaning carbon deposits: Hydrogen-oxygen decarbonization machines use atomization to simultaneously clean the intake tract and gasoline engine cylinders; drip cleaning or soaking involves removing each cylinder's spark plug, pouring cleaning fluid into the cylinder to soak until most carbon deposits dissolve, then extracting it with professional tools; fuel additives are relatively economical and effective, though they cannot completely remove all deposits and contain corrosive chemicals; for severe carbon deposits, it is recommended to manually disassemble and clean the engine's intake tract and cylinder head.
