Roewe i6PLUS owners come to ask how often the throttle is cleaned?

Throttle, also known as throttle body, is an adjustable valve to control air to enter the automobile engine, and it is also an important part of the EFI automobile engine system. When air enters the air filter, then enters the intake pipe and mixes with gasoline to form a combustible mixture, and then enters the combustion chamber of the engine block to do work, the throttle valve is the throat of the automobile engine.

As for how often the throttle valve is cleaned, manufacturers generally recommend cleaning it every 10000 km to 20000 km. In fact, there is no hard requirement for this. Many factors determine the cleaning frequency of your car throttle. For example, whether driving at a low speed in the urban area or driving in a dusty environment will have an impact on the cleaning cycle of the throttle.

Too high cleaning frequency is not good for the throttle. It is suggested that the owner can check the throttle opening every 10,000 kilometers, and clean it if it exceeds the normal range. Also, if a large amount of impurities and dust accumulate on the accelerator, it will affect the intake of the engine, which is most obvious when starting the vehicle. At this time, pay attention, this is the throttle sending a cleaning signal. For some Japanese engine control systems, generally speaking, fuel injection and ignition time are calculated by measuring air flow. On the other hand, the accuracy of air flow measurement is very strict, even a slight blockage will lead to abnormal engine operation. But for some American engines, there is no such great response without air flow as the calculation basis.

Different vehicles and different working environments will cause inconsistent engine throttle cleaning time. It is worth noting that there is no regulation on how often to clean the throttle valve in the market at present. If there is such a regulation, it is an abnormal regulation, indicating that the design of the car is flawed. It should be noted that vehicles that often need to clean the throttle are faulty vehicles. Some vehicles with electronic throttle can contact the maintenance station and make adjustments through ECU software upgrade. In addition, it is worth noting that if the problem is still not solved by repeatedly cleaning the throttle through the maintenance station, it is recommended to return the car (generally impossible) or change it.

Dirty throttle is mostly caused by poor air quality and poor oil quality. The carbon deposit produced in the process of gasoline combustion will infect the throttle valve due to negative pressure, which will make it not close well, thus increasing the intake air, causing signal transmission errors, leading to high fuel consumption and engine idling jitter.

Therefore, the throttle is easy to get dirty. Too dirty will lead to jitter and fuel consumption. Whether the automobile acceleration and deceleration operation is flexible is closely related to whether the throttle is clean. Drivers should pay attention to the cleaning and maintenance of the throttle.

For large automobile manufacturers, the accelerator can be cleaned by an automatic ultrasonic cleaner, and the automobile repair shop can choose a slightly smaller industrial ultrasonic cleaner, such as a standard single-slot ultrasonic cleaner.
