How to Clean Carbon Deposits?

Clearing carbon deposits is relatively effective with the walnut shell blasting method. Relevant introductions are as follows: 1. Hazards: Carbon deposits pose significant hazards to the engine. If carbon deposits accumulate on the intake system, it can lead to incorrect air intake by the engine, resulting in an improper air-fuel ratio. An improper air-fuel ratio will affect the engine's power output and fuel consumption. If carbon deposits are in the combustion chamber, it can increase the compression ratio of the combustion chamber, leading to engine knocking. 2. Knocking: Knocking affects the engine's power output and fuel consumption, and it can also damage the engine. Severe knocking may even cause phenomena such as piston cracking or connecting rod deformation in the engine.
I've been driving for years, and carbon buildup is really annoying. When you drive in the city with frequent traffic jams for a long time, carbon deposits accumulate, leading to sluggish acceleration and higher fuel consumption. The cleaning methods are quite simple: you can go to a repair shop for throttle valve cleaning or an intravenous drip cleaning, which involves injecting a special cleaning agent into the system to dissolve the carbon deposits; or you can buy fuel additives yourself and add them to the fuel tank, then drive a few hundred kilometers to slowly clean it. I often use additives—it's cost-effective and convenient—but severe carbon buildup still requires professional treatment. I recommend avoiding prolonged engine idling, taking a highway trip every weekend to flush out carbon deposits, consistently using high-octane gasoline, and regularly checking the air filter during maintenance. Prevention is more important than cleaning, saving both hassle and fuel.
I often tackle carbon buildup myself, which I find very practical. There are mainly DIY methods for cleaning carbon deposits: first, use a diagnostic tool to confirm it's a carbon buildup issue, then purchase throttle body cleaner to spray into the intake, but be careful not to damage components; or add fuel system cleaner to the tank and drive through several tanks of fuel. Prevention is key—I use high-quality gasoline, change the oil regularly, and add additives every 5,000 kilometers. Avoid prolonged driving in congested areas, and occasionally run the engine at high speeds to help burn off residues. If you're unsure about DIY, don't force it—seek professional service for safety.
