How to Reduce Carbon Deposits in Cars Through Driving Habits?
2 Answers
To reduce carbon deposits in cars, various driving methods should be adopted. Here are the detailed measures: 1. Avoid prolonged idling: Develop good driving habits and turn off the engine promptly during heavy traffic jams. 2. Drive at high speeds more often: Regularly engage in high-speed driving to fully utilize the airflow's scouring effect on the intake pipe, thereby preventing carbon deposit buildup. Also, avoid prolonged low-speed driving, short-distance trips, and gear disengagement. 3. Avoid using low-quality fuel: When refueling, pay attention to the quality of gasoline and objectively choose the appropriate fuel. 4. Frequently replace air and fuel filters: Replace or clean car parts like fuel filters to ensure the engine absorbs sufficiently clean air. 5. Regularly clean the throttle valve: When carbon deposits form on the throttle valve, it can cause the system to collect incorrect information, leading to issues such as inaccurate fuel injection and carbon deposit accumulation.
I've given this issue a lot of thought during long-distance drives. The fundamental principle is to avoid keeping the engine constantly at low RPM, especially in manual transmission vehicles. When driving at low speeds in high gears, the injected gasoline doesn't burn completely, and over time, those black carbon deposits accumulate on the valves, spark plugs, and fuel injectors. Running the engine at around 3000 RPM for an hour or so on the highway is particularly effective for cleaning carbon deposits, allowing the warmed-up engine to 'breathe.' Additionally, always choose reputable, major brands when refueling – incomplete combustion of impurities in gasoline can easily clog fuel injectors. Don't skimp on the air filter either; replace it when it's dirty, as clean intake air promotes more efficient combustion. And if you're parked waiting for more than two minutes, it's more economical to simply turn off the engine.
