Flushing the intake system won't damage the three-way catalytic converter. This process, often referred to as "flushing," is a non-intrusive cleaning method developed specifically for addressing carbon deposits on fuel injectors, intake valves, and combustion chambers. A foaming cleaner is introduced into the combustion chamber, where, under high temperatures, it breaks down continuously, addressing carbon deposits on the fuel injectors, intake valves, and combustion chamber. The deposits are then expelled from the vehicle through vigorous vibration and engine operation.
What are the aftereffects of flushing a car's intake system?
Under normal circumstances, there are no adverse effects after flushing a car's intake system. However, if counterfeit intake cleaners are used, the following issues might arise:
1：Residual carbon deposits in the combustion chamber can disrupt engine combustion, possibly leading to engine knocking.
2：The car's idle speed might increase, with noticeable vibrations. This could be due to an incomplete cleaning process.
3：If not done correctly, there's a chance that the three-way catalytic converter might get clogged.
4：Carbon residues on the valves might lead to "sticking" of the valves. If the compression and exhaust valves cannot close properly, the engine might exhibit symptoms like trembling, rapid running, and abnormal noises.
Even though flushing is convenient, affordable, and saves a lot of time for car owners, it's still advisable to physically remove and clean components like the intake tract, throttle body, fuel injectors, and combustion chamber when necessary. Intake system cleaners are mostly effective against minor carbon build-ups. Severe carbon deposits might not be addressed effectively through this method.
