2. The meaning of an air flow meter

Air flow meter English [e ə (r) fl əʊˈ mi ∝ t ə (r)] American [er flo ʊˈ mi ∝ t ə r] Network airflow meter

3. Do you know the English abbreviation for air flow meter? The abbreviation for air flow meter is MAF. Additional explanation: An air flow meter is a flow meter that measures flow based on Faradays law of electromagnetic induction. The advantages of an air flow meter are minimal pressure loss and a wide range of measurable flow rates. The ratio of the maximum flow rate to the minimum flow rate of an air flow meter is generally above 20:1, and it is suitable for a wide range of industrial pipe diameters, up to 3m. The output signal is linear with the measured flow rate and has high accuracy. It can measure the fluid flow rate of acid, alkali, salt solutions, water, sewage, corrosive liquids, as well as mud and slurry with conductivity ≥ 1 μ s/cm. But air flow meters cannot measure the flow of gas, steam, and purified water. Principle introduction: During the use of an air flow meter, the gas flow passes through the meter and drives the turbine blades to rotate. The number of revolutions of the impeller is directly proportional to the volume of gas passing through the air flow meter. There is a specially designed patented guide frame installed at the inlet of the flowmeter, which accelerates the airflow entering the flowmeter as the flow rate increases. The design of the guide frame can eliminate any potential fluid disturbances, such as eddies or asymmetric flows. The driving force on the turbine blades also increases simultaneously. Ensure high-precision measurement of the flowmeter within the allowable error range, even in low flow conditions. The airflow acting on the turbine blades is axial, and the turbine device is located on the main drive shaft, which is equipped with high-strength ball bearings. After the gas passes through the turbine blades, the rotation of the turbine blades is reduced by the gear set. The pressure in the inlet channel of the air flow meter is restored, and the channel design ensures the optimization of the flow state.

4. Will there be any accidents when pulling out the oil dipstick while the engine is starting?

Something will happen. When the engine is running after driving, the dipstick cannot be pulled out. When the oil dipstick is removed, there is an additional hole in the crankcase that communicates with the atmosphere, and air enters the relatively sealed housing, causing the car to shake. Precautions for using the oil dipstick: Before checking the oil dipstick, it is necessary to park the car in a relatively flat parking space and wait for about 10 minutes to ensure the accuracy of the oil level.

5. Function of Automobile Air Flow Meter

Air Flow Meter (AFM) is the abbreviation for Manifold Air Flow Meter (MAFM), also known as Air Flow Sensor (AFS). Its function is to detect the amount of intake air into the engine and convert the intake air information into an electrical signal to input into the electronic control unit (ECU) for calculating and determining the fuel injection amount.
