How to Use the Car Odometer AB?

Car odometer AB is used as follows: when starting from point A, reset one of the trip data to zero and start the car. Upon arriving at point B, check the data on the trip to know the distance between the two points. The working principle of the odometer is based on the known diameter of the car's wheels. By calculating the circumference of the wheel, the number of rotations required for the wheel to cover one mile is determined. The odometer automatically records the number of wheel rotations and divides it by the number of rotations corresponding to one mile to obtain the distance traveled. The method to adjust the odometer is: 1. Unplug the odometer sensor connector of the drive shaft under the car's hood; 2. Insert the output plug of the mileage adjuster into the signal socket of the sensor; 3. Plug the mileage adjuster into the cigarette lighter; 4. Turn the car key to start the dashboard and adjust the adjustment button on the mileage adjuster; 5. Adjust the speed as needed.

Solutions for Engine Vibration After Fuel Injector Cleaning

The reason for engine vibration after fuel injector cleaning is: It's quite normal to experience vibration after cleaning fuel injectors. The vehicle's ECU has a self-learning function that stores pre-cleaning fuel injection data. When injector nozzles are clogged with carbon deposits, the throttle valve automatically increases its opening to maintain idle air intake. After cleaning, the throttle valve still uses the clogged data, causing unstable idle and severe vibration due to excessive throttle opening. Simply resetting the throttle valve to factory settings can resolve this issue. The working principle of fuel injectors is: High-pressure fuel is pumped into the injector's supply port, creating pressure inside that acts on the injector's conical surface. When oil pressure exceeds the set value, the injector valve opens, spraying atomized fuel through small nozzles into the engine cylinder for combustion, driving piston reciprocation.

How to Use the Internal and External Air Circulation in a Car?

Here are the methods for using the internal and external air circulation in a car's air conditioning system: 1. On the control panel of the car's air conditioning, there is a button to switch between internal and external circulation. You can toggle it using this button. 2. When driving in congested urban areas, it is recommended to use the internal circulation mode. For long-distance trips or highway driving, the external circulation mode is advisable. Recommendations for using internal and external air circulation in cars: 1. The car's air conditioning system is equipped with an air filter, which is designed to filter out dust and particulate matter from the air. 2. The air filter needs to be replaced regularly. Failure to replace it for an extended period can result in unpleasant odors in the car's air conditioning and can be harmful to the health of passengers. 3. When replacing the air filter, it is important to choose products from reputable brands.
