What are the causes of carbon deposits in cars?

The causes of carbon deposits in cars are: 1. Drivers' long-term poor driving habits. Many drivers are reluctant to step on the accelerator to save fuel and protect their cars, but this driving style not only fails to save fuel but also increases engine carbon deposits; 2. Poor quality gasoline. When there are many impurities in the gasoline, carbon deposits will form after combustion in the engine; 3. Aging or damage to the engine's carburetor. The engine is the heart of the car, and the carburetor is the heart of the engine. If the carburetor is aging or malfunctioning, gasoline will enter the engine without being fully atomized before combustion, leading to the formation of carbon deposits. Additionally, whether the carburetor can fully atomize gasoline is also greatly related to air quality.
After driving for so many years, I've noticed that carbon buildup is mostly caused by incomplete combustion. When the car engine is running, the mixture of fuel and air burns to generate power, but if the combustion isn't thorough, carbon residues will accumulate on the cylinders or pistons. The most common reason is frequent short-distance driving, like when I pick up my kids—just a few kilometers—the engine doesn't even warm up before shutting off, leaving unburned fuel. Another cause is urban traffic congestion, where low-speed driving or idling puts the engine under light load, reducing combustion efficiency. Using low-quality gasoline with more impurities can also accelerate carbon buildup. I remember during one maintenance check, opening it up to find a black, grimy mess. Since then, I make sure to take the car on a high-speed run once a week to fully heat up the engine, which works well. Also, in areas with poor air quality, the air filter can get clogged, affecting airflow and leading to combustion issues—regularly replacing the filter is crucial. In short, carbon buildup not only saps the car's power but can also increase fuel consumption. Preventing it early saves both hassle and money.
