How to Prevent Carbon Buildup in Cars?
1 Answers
Avoiding carbon buildup in cars can be achieved through the following methods: 1. Use high-quality fuel: Impurities such as paraffin and gum in fuel are the main components of carbon buildup. Therefore, cleaner fuel has a weaker tendency to form carbon deposits. Always choose reputable gas stations when refueling to ensure relatively better fuel quality. It's important to note that high quality does not mean high octane rating; the octane number only represents the gasoline's resistance to knocking, not its quality or cleanliness. 2. Avoid prolonged idling: Extended idling increases the time it takes for the engine to reach normal operating temperature, slowing the evaporation of gasoline sprayed onto the back of the intake valves, which leads to carbon buildup. Additionally, frequent idling reduces the airflow into the engine, weakening the scouring effect on carbon deposits and promoting their accumulation. 3. Drive at high speeds more often: Carbon buildup mainly occurs when the engine runs at low RPMs, resulting from incomplete fuel combustion. This is especially common in urban traffic congestion. At high speeds, the engine operates at higher RPMs, and the movement of the pistons accelerates, which can help shake off internal carbon deposits and expel carbon residue from the exhaust. 4. Change the engine oil promptly: Engine oil is crucial for the car's engine, and timely oil changes offer significant benefits, such as improving engine lubrication and inhibiting carbon buildup inside the engine. Therefore, always change the oil on time and ensure its quality.
