1. The air flow meter in a car plays a significant role. Do you know its working principle? Gas flow meter, also known as gas flow meter, is one of the most crucial sensors in electronic fuel injection engines. This device converts the inhaled airflow into electrical signals and sends them to the electronic control unit (ECU). It measures the airflow entering the engine as one of the basic signals for determining fuel injection. Several other types of air flow sensors, such as valve type air flow sensors and Karman vortex air flow sensors, are controlled by microcomputers for fuel injection. The sensor part of an air flow meter sensor is made of non-metallic materials and is generally divided into two categories: one is used for measuring air and fluid, and the other is used for measuring gas flow. Gas flow meters are used to measure the flow rate of fluids. There are three sensors on the flowmeter, namely the rotor, electromagnetic flowmeter, and turbine flowmeter. The rotor is the core component of the turbine flowmeter, and there is a channel above the flowmeter. By rotating the rotor on the flowmeter, the fluid flow on the flowmeter is converted into flow through the channel. The electromagnetic flowmeter uses a magnetic field as a sensor. Electromagnetic flowmeter is used to measure flow rate, which utilizes an electromagnet to measure flow rate. A turbine flowmeter is also a type of flowmeter that utilizes a turbine and a high-speed electromagnetic coil, with a rotor mounted on a shaft. The rotor rotates the buried rotor on the flowmeter, and as the rotor rotates, the turbine and electromagnetic coil rotate synchronously. When the turbine rotates, the fluid on the flowmeter continuously flows downwards, and the speed of the turbine rotation slows down. This pulse is applied to the rotating shaft of the turbine, and the gear on the rotating shaft rotates once, and the gear will rotate accordingly. The longer the gear rotates, the greater the angle of rotation, and the better it can measure the flow rate. Gas flow meters are manufactured according to some special process requirements. When gas is measured through a flow meter, it needs to be mixed with air, water vapor, dust, and mist.

3. What are the symptoms of a broken car air flow meter?

A broken car air flow meter can mainly affect the engines power performance, and may cause symptoms such as unstable idle speed.; Increased fuel consumption; Inability to accelerate; The exhaust emissions are seriously polluting. With the slow development of our countrys industry, the types of air flow meters have also undergone many changes. According to the division of the times, air flow meters are divided into four categories: L-type, D-type, hot wire type, and hot film type. The structure of the first generation L-shaped air flow meter was the simplest, but of course, there are no more models in use now. The structure of the air flow turbulence meter is shown in the following figure. It uses a Wheatstone bridge composed of a thermistor, platinum wire, and two precision resistors inside. The engine ECU provides current to the power transistor to heat the platinum wire base to a certain temperature.
