Is it useful to clean the throttle because of high fuel consumption?

Car fuel consumption is high, and cleaning the throttle has a certain effect. Throttle can also be said to be the "throat" of the engine. Connect the air filter to the upper part and the engine cylinder to the lower part. The main reason of carbon deposition in throttle is that engine oil and gasoline vapor will partially adhere to throttle after entering the intake system through the gas exchange tank of crankshaft, and a small part is impurities in the air. When the air intake of the engine is small, the throttle is easy to deposit carbon. In other words, throttle carbon deposition mainly occurs when the engine is idling. When rotating at high speed, the air flow is large and has an impact effect, so it is difficult for oil and gas to stick to the throttle. Therefore, reducing idle time and operating mode with high speed limit and low speed can reduce carbon deposition in throttle. After carbon deposition in the throttle, the most important influence is idling. When turning at idle speed, the throttle opening is relatively small, and carbon deposition seriously causes imbalance of mixed flow ratio, which leads to engine vibration and increased fuel consumption.
