How to Drive to Reduce Carbon Deposits in Cars?
2 Answers
You should adopt various methods while driving to reduce carbon deposits in cars. Here are the detailed explanations: Avoid prolonged idling: Develop good driving habits, such as turning off the engine promptly during heavy traffic congestion. Drive on highways more often: Schedule regular high-speed driving to fully utilize the airflow to flush the intake pipes, thereby preventing carbon deposit buildup. Also, avoid prolonged low-speed driving, short-distance trips, and gear disengagement. Avoid using low-quality fuel: When refueling your car, pay attention to the quality of gasoline and objectively choose the appropriate fuel. Regularly replace air and fuel filters: Replace or clean car components like fuel filters to ensure the engine absorbs sufficient clean air. Clean the throttle body periodically: When carbon deposits form on the throttle body, it can cause the system to collect incorrect information, leading to issues like inaccurate fuel injection and further carbon buildup.
After driving for so many years, I've found that reducing carbon buildup relies on adjusting driving habits, with the key being to avoid keeping the engine in inefficient states. For example, don't let the car idle for long periods when parked; in summer, waiting with the AC on can easily cause the engine to run idle, accumulating carbon deposits—I make it a habit to turn off the engine if it exceeds a minute to save fuel and reduce buildup. Highway driving is the most effective; I take time every week to drive on suburban highways, maintaining speeds above 100 km/h for over ten minutes. Keeping the RPM high helps burn off some accumulated carbon. During regular driving, focus on smooth acceleration and gear shifts; avoid slamming the accelerator or brakes, keeping the RPM between 2000 and 3000 to ensure more complete fuel combustion. In winter, I always let the engine warm up for two to three minutes before driving to minimize incomplete combustion due to low temperatures. These habits keep my car's engine clean, and mechanics rarely find issues during maintenance.
