What Are the Parts to Clean Carbon Deposits in an Engine?

[DelTaylor]

Engine carbon deposit cleaning involves the following parts: 1. Cleaning throttle body carbon deposits: Remove the engine cover, detach the throttle body, clean it with a cleaning agent, dry it with a cloth, and reinstall it. It is recommended to clean every 20,000 kilometers. 2. Cleaning internal engine carbon deposits: Open the oil cap, pour in the entire can of cleaner (mixed with old engine oil), close the oil cap, start the engine and let it idle for 10 minutes before shutting it off. Cleaning internal engine carbon deposits dissolves sludge, gum, moisture, and metal debris inside the engine, reducing contamination of new oil and extending the engine's lifespan. It is recommended to clean every 40,000 kilometers. 3. Cleaning fuel system carbon deposits: This includes cleaning the fuel injectors, combustion chamber, spark plugs, and throttle valve. The goal is to address issues such as insufficient power, increased fuel consumption, engine shuddering, poor acceleration, or difficulty starting caused by carbon deposits, gum, and dirt in the fuel system. No disassembly is required; simply add a specialized fuel system cleaner to the fuel tank periodically for effective cleaning. It is recommended to add the cleaner every two fuel tank refills. 4. Cleaning intake system carbon deposits: This mainly involves cleaning carbon deposits in the intake ducts and intake manifold. The purpose is to remove carbon buildup inside the intake system, improve airflow and speed, and reduce engine shuddering and idle instability. Typically, 4S shops or repair shops use a hanging bottle method to inject intake cleaning fluid into the intake pipe. The cleaner participates in combustion to remove carbon deposits on valves, combustion chambers, and piston heads. For naturally aspirated engines, cleaning every 40,000 kilometers is recommended; for turbocharged engines, cleaning every 20,000 kilometers is advised. Carbon deposits are a coking substance formed from unsaturated olefins and gum in fuel under high temperatures during engine operation. They can adhere to various engine parts, significantly impacting the vehicle by reducing engine power, increasing fuel consumption, and in severe cases, causing engine knocking, piston damage, or even excessive oil consumption. They also affect the vehicle's exhaust emissions.
