How to Prevent Carbon Buildup in Car Engines?

[AdrianaFitz]

Avoiding carbon buildup in cars can be achieved by using high-quality fuel, avoiding prolonged idling, frequently driving at highway speeds, and timely oil changes. Below is relevant information: 1. Impurities like paraffin and gum in fuel are the main components that form carbon deposits. Therefore, higher-purity fuels have a weaker tendency to form deposits. Always choose reputable gas stations to ensure relatively better fuel quality when refueling. 2. Prolonged idling extends the time for the engine to reach normal operating temperature, slowing the evaporation of gasoline injected behind the intake valves and leading to carbon buildup. Additionally, frequent idling reduces airflow into the engine, weakening the scouring effect on deposits and promoting their accumulation.
