Is Engine Carbon Deposit Cleaning Necessary?

Engine carbon deposit cleaning is necessary. The following are the hazards caused by carbon deposits: 1. Decreased engine power: After carbon deposits form inside the engine, the engine's power will decrease. When driving, you may feel that the car is not as powerful as before, with a sensation of not moving without pressing the accelerator. This leads to a decline in both the engine's performance and fuel efficiency, making it harder to drive and more fuel-consuming. Additionally, it significantly impacts vehicle emissions. 2. Exhaust valve blockage: When carbon deposits form in the engine's intake and exhaust areas, especially at the exhaust valve, it can easily cause "secondary valve" issues. The carbon deposits attached to the exhaust valve hinder heat dissipation. Although the exhaust valve is treated with special processes, excessive carbon deposits and high temperatures without proper heat dissipation can still cause problems. 3. Cylinder scoring: Carbon deposits on the piston head can easily create multiple ignition points during engine combustion, leading to incomplete combustion and knocking. This also results in decreased engine power, and in severe cases, may cause cylinder scoring. 4. Fuel injector clogging: In direct-injection engines, carbon deposits in the cylinder can easily clog the fuel injectors. Clogged fuel injectors cause engine shaking and weak acceleration.

Is Hydrogen-Oxygen Carbon Removal Necessary at 4S Stores?

If the vehicle has slight carbon deposits, the hydrogen-oxygen carbon removal service offered at 4S stores can be considered. Below is relevant information about hydrogen-oxygen carbon removal: Principle of Hydrogen-Oxygen Carbon Removal: A machine is used to electrolyze water into hydrogen and oxygen. The hydrogen is then introduced into the engine's combustion chamber through the airflow. Leveraging hydrogen's high permeability and calorific value, it effectively cleans the carbon deposits in the combustion chamber. Disadvantages of Hydrogen-Oxygen Carbon Removal: It may cause damage to the vehicle's catalytic converter, especially in older models. These components may already be aged, and if they fail prematurely due to carbon removal, it may not be cost-effective.
