1. What are the types of mass flow meters?

2. What is the normal value of Passat intake flow?

The normal value of Passat intake flow is 2.0-4.5g/s, which can be observed through data flow using a detector. The channel number is 002, Zone 4. The detection conditions for air flow meters:

1. The 20th fuse must be normal;  

2、 The coolant temperature should be at least 85 ℃;  

3、 All electrical equipment, such as lighting, rear windshield cleaning and heating, must be turned off;  

4、 Turn off the air conditioning;

5、 On vehicles with automatic transmissions, the Husen shift lever is placed in P or N. Additional information: On October 31, 2018, the all-new Passat from SAIC Volkswagen was officially launched in Kunming, with a price range of 189900 to 288900 yuan. The new car is built on the MQB platform, with an increased body size and equipped with 1.4T and 2.0T engines. In terms of dimensions, the new car measures 4933/1836/1465mm in length, width, and height, with a wheelbase of 2871mm and a drag coefficient of only 0.269; The rear of the car is equipped with full LED taillights with flow light steering function, and the exhaust adopts a hidden layout. The word PASSAT is exclusively marked below the car logo. In terms of interior:

1. The interior is still in Volkswagen style, and the air conditioning vents are designed in a through style. The panoramic sunroof and the Hui Ang are the same, with 8-way electrically adjustable perforated leather seats with electric heating, ventilation, and massage functions.

2、 The equipped 10.2-inch full LCD instrument panel can be personalized switched between three different modes. The 9.2-inch pure front navigation screen i

3、 In terms of auxiliary systems, it is equipped with adaptive headlights, blind spot monitoring, adaptive cruise control, lane keeping system, reverse emergency braking, preventive passenger protection system, AEB brake assist, panoramic imaging, and MKE intelligent fatigue monitoring system.

3... Automotive expert: My car is a Passat Lingyu 10 model 1.8t. The air flow meter is broken. What is the phenomenon? _ Baidu After the Passat Lingyu 10 1.8T air flow meter is damaged, the following phenomena may occur: 1. Unstable engine operation. The core function of the air flow meter is to measure the amount of air entering the engine and transmit the data to the engine control unit (ECU). If the sensor is damaged, the intake signal received by the ECU may be abnormal (such as a value that is too high or too low), resulting in a mismatch in fuel injection quantity. Typical manifestations include sudden engine shutdown during driving, severe engine shaking at idle, especially during cold start or low-speed driving. 2. Decreased power and increased fuel consumption. Inaccurate intake data can directly affect the combustion efficiency of the engine. If the ECU reduces the fuel injection amount based on an incorrect signal, it will cause the mixture to be too lean, resulting in weak acceleration and difficulty climbing; If the fuel injection quantity is increased, it will cause the mixture to become too rich, resulting in a significant increase in fuel consumption. Some car owners may observe a sudden increase of 10% -20% in short-te
