Is it really necessary to clean the throttle? Car owners are always asked to clean the throttle body when they do repair or maintenance at the 4S store. They say it can remove carbon deposits, improve power and reduce fuel consumption. However, is it really necessary to clean the throttle body frequently? So I think it is necessary to discuss with you the necessity of cleaning the throttle body and welcome you to come along and leave your comments to express your opinion.
The Effects of Carbon Buildup on the Throttle Body
Carbon buildup on the throttle body mainly affects idle speed, causing the mixer ratio to become unbalanced, resulting in engine shuddering and increased fuel consumption. The impact of carbon accumulation on the throttle opening at high speed is relatively small. Although excessive carbon buildup can cause the throttle to stall, this is a rare occurrence. Throttle carbon cannot be cleared by increasing speed, so manual cleaning is necessary.
When to Clean the Throttle Body
Engines with smaller air intake are more likely to accumulate carbon on the throttle body, especially at idle speed. At high RPM, the airflow and impact effect are higher, and oil vapor is less likely to adhere to the throttle body. Therefore, reducing idle time and driving with fewer high gears and low speeds can reduce the accumulation of carbon on the throttle body.
When to Clean the Throttle Body
Throttle cleaning is not always necessary, and car owners should judge according to their own situation. If the idle speed and fuel consumption are stable, cleaning the throttle body every 20,000km is sufficient. If the driving environment is good with no idle shaking, cleaning every 50,000km is feasible. However, if the driver frequently faces traffic jams, or lives in areas with sandy weather, or is an off-road enthusiast, cleaning the throttle body every 20,000km is recommended.
