What are the effects of carbon deposits on a car?

[MacBeckett]

Effects of carbon deposits on a car: Causes poor engine performance, resulting in abnormal phenomena such as difficulty starting, unstable idling, poor acceleration, backfiring when accelerating sharply, excessive exhaust emissions, and increased fuel consumption. Carbon deposits refer to a mixture accumulated on the engine's valves, combustion chamber, and intake pipes, formed when the engine's fuel does not fully combust, producing hydrochloric acid and resin-like adhesives under high temperature and oxygen catalysis, which adhere to the surfaces of components. Methods to remove carbon deposits: Engine disassembly and cleaning are required to thoroughly remove carbon deposits from components using detergents, ultrasonic methods, etc.

Having driven for over twenty years, I've found that carbon buildup in cars has a significant impact. It directly reduces engine power output, making the car respond slower when stepping on the gas and feel weak when climbing hills—it's like running in wet shoes. Fuel consumption also skyrockets, going from about 7-8 liters per 100 kilometers to possibly over 10 liters, wasting money on gas. Carbon buildup can also make cold starts difficult, especially on winter mornings when the engine struggles to turn over, buzzing for a long time—what a hassle. If left untreated for too long, it can lead to engine knocking, which sounds painful to hear, or even cause the car to break down midway. To prevent this, I add a bottle of fuel cleaner every 10,000–20,000 kilometers and regularly take the car on the highway to flush out the engine. Remember, ignoring carbon buildup for too long can lead to hefty repair bills.

Carbon deposits in cars can really hit your wallet hard. Since my car developed carbon buildup, the fuel consumption has increased significantly, costing me an extra few hundred bucks every month on gasoline, which has tightened my household budget. The engine performance has also deteriorated, feeling sluggish and weak during acceleration, especially noticeable when the air conditioning is on. Carbon deposits can easily lead to emission issues, with exhaust fumes smelling pungent, often failing the annual inspection and requiring expensive repairs at the auto shop. A friend of mine had spark plug problems due to carbon buildup, with black smoke puffing out at startup, costing over a thousand yuan to fix. Regular maintenance, like checking every 5,000 kilometers or occasionally using cleaning additives, can save a lot of trouble. Carbon buildup drives up car ownership costs—it's no small matter.

Carbon deposits can make the engine interior dirty, with carbon buildup on the cylinder walls and intake passages. This obstructs the mixing of fuel and air, leading to incomplete combustion and reduced power, making the car feel sluggish. Fuel consumption also increases, wasting gas unnecessarily. Carbon deposits may also cause unstable idling, sometimes with severe shaking. Regular cleaning is crucial; using detergents or manual removal can restore performance. When driving, I pay attention to carbon deposits and notice they make emissions dirtier, increasing pollution.
