The working principle of car flow sensor is introduced

Abstract: the working principle of car flow sensor is introduced information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Abstract: the flow sensor is one of the key components of efi system, it directly affects the vehicle's normal driving, car use air flow sensor is a flowmeter, the effect is measured by sensors of air flow within a certain time, and will be empty. More flow meter manufacturers choose model price quote you are welcome to inquire, here is the car flow sensor principle introduction for details. Flow sensor is one of the key components of efi system, it directly affects the vehicle's normal driving, car use air flow sensor is a flowmeter, the effect is measured by sensors of air flow within a certain time, and the air flow signal to ECU. This paper introduces the working principle of car flow sensor. Flow sensor is one of the key components of efi system, it directly affects the vehicle's normal driving, car use air flow sensor is a flowmeter, the effect is measured by sensors of air flow within a certain time, and the air flow signal to ECU. ECU according to the signal to monitor the working condition of engine, the calculation of fuel supply. Air flow is big, show that the engine is accelerating; Air flow is small, indicates the engine in slow or idle running. Working principle: when enter the body of a throttle air flows through the sensor, and part of heat away, the greater the air flow, the more heat away. To keep the temperature of a sensor at a constant temperature, it needs additional current to heat induction. By measuring the voltage of the current sensor to determine the size of the air flow. Made from metal platinum wire in the air flow sensor, near to the throttle body of air passage. The air flow sensor adopts the huis bridge principle, in the air flow of electricity for air cooling effect and make the resistance change, bridge and so out of balance, control circuit automatically increase the voltage, increase the flow of electrical current, make the resistance varies with temperature rise, bridge to regain balance. In the process of regulating, air flow sensor to the engine electronic control module ( ECU) Voltage signal changes over the air flow, the air stream near the compensation also has resistance wire, so as not to make a bridge with the change of air temperature out of balance. After fouling of air flow sensor, voltage signal to ECU will prohibit, dirt will affect the radiation at this time, lower the cooling effect. When the air flow rate increases, the temperature decrease slowly, its electrical resistance variation also reduced accordingly, so can't accordingly increase the voltage and the flow of current, so that to the ECU signal voltage on the low side, mixture too thin. Although type air flow sensor with a burning net circuit, namely at every time of downtime, ECU automatically give high temperature 1000 ℃ heating 1 s, in order to burn off the dirt and dust on the, but parts, especially in remote areas in China due to the use of fuel quality is too low, tempering inlet pipe, caused by excessive impurities and carbon deposit cementation on the metal platinum wire, so the purification of a single heating device can also be difficult to remove. Therefore, you must remove the air flow sensor directly spray cleaning, to return to its normal function. Introduce after zui, air flow sensor to g/s for the unit to measure the flow of air into the engine. Air flow measurement value is reflected the throttle opening and engine load, air volume and engine load and the intake manifold absolute pressure sensor or similar to the relationship between vacuum sensor signal. Air traffic signal should maintain a relatively stable, when the car at a constant speed change gradually as the throttle opening, and severe changes in acceleration. Powertrain control module (PCM USES air traffic control fuel supply of information. Produce a difficult to be measured in the test of 32 ~ 150 hz frequency signal. The change of signal and the air flow will be a certain proportion. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.

There are a lot of businesses today that are very much in demand and one of them is a mass flow meter.
