What is the purpose of the bypass airway of the automotive wing type air flow meter? What is the principle, next to the throttle valve ..
The bypass airway of the automotive wing type air flow meter - the idle air channel [with adjustment screws to adjust the idle air flow rate]. The function of the bypass airway for Zen meditation and valve positioning is the same as above, except that it does not include adjustment screws. That is considered from the perspective of control strategy in automotive research and development. You just need to know how it works. Only those who conduct research and development know that it is too profound and mysterious.

3. How to check the quality of an air flow meter?
The method of detecting air flow meter The quality of air flow meter is crucial for the control system of electronic fuel injection engine, and its main responsibility is to measure the amount of air entering the engine.. If the vehicle experiences unstable idling, weak refueling, black smoke emission, or difficulty starting during travel, it is highly likely that the air flow meter has malfunctioned. The following are several methods for detecting air flow meters: Inspection of wing type air flow meters: -5-wire air flow meters have a vibration core without an oil pump switch, and their wiring terminals have specific names and functions, while 7-wire air flow meters have built-in oil pump switches. It is necessary to understand the functions of each port for inspection. The testing process for automotive air flow meters: - Determine through power supply voltage testing and signal voltage testing, where signal voltage testing is a key mean

4. Types and working principles of air flow sensors
Currently, common air flow sensors can be divided into blade air flow meters, Karman vortex air flow meters, hot wire air flow meters, and hot film air flow meters according to their structural types.
. According to the detection method, it can be divided into two categories: flow rate type and velocity density type. Flow rate type uses air flow sensors to directly measure the amount of air inhaled into the engine. Flow rate type air flow sensors mainly include wing type, Kalman vortex type, hot wire type, and hot film type. Among them, wing type and Kalman vortex type flow sensors measure the volume of inhaled air, so the air mass needs to be calculated by the electronic control unit based on information such as intake temperature; Hot wire and hot film methods directly measure the quality of inhaled air, so their accuracy is higher. Principle: Convert the amount of air drawn into the engine into an electrical signal and send it to the ECU as one of the main criteria for determining
