A brief analysis of the enterprise's investigation and research on the automobile air flow meter

Abstract: Analysis of the investigation and research information of automobile air flow meter by enterprises is provided by excellent manufacturers of flow meters and flow meters. Wenzhou Guoda Electric Co., Ltd. found that the automobile air flow meter is used in the modern automobile gasoline injection system, installed between the air filter and the throttle body, used to measure the amount of air inhaled into the engine, as a basis for determining the basic injection. Parameters of oil quantity. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following is the details of the research articles on the investigation and research of automobile air flowmeters by enterprises. Wenzhou Guoda Electric Co., Ltd. found that the automobile air flow meter is used in the modern automobile gasoline injection system, installed between the air filter and the throttle body, and used to measure the amount of air inhaled into the engine, as the basic fuel injection amount. parameter. Hot wire air flow meters can be divided into two types: mainstream measurement methods and bypass measurement methods according to their platinum installation positions. Hot wire and hot film air flow meters have a fast response speed and can reflect changes in air flow within a few milliseconds, so their measurement accuracy is not affected by the pulsation of intake air flow. Especially when the engine is under heavy load and low speed, the intake air pulsation is large. Because the hot wire or hot film air flow meter is used to measure the intake air, the air measurement is accurate, and the best air-fuel ratio can be guaranteed under any working conditions. , The engine's starting performance and acceleration performance are good. The hot wire of the mainstream air flow meter is a diameter of 70μThe platinum wire of m is installed in the sampling tube, and the sampling tube is installed in the central part of the main air intake. The platinum heating wire of the bypass air flow meter is wound on the ceramic spiral tube and installed on the bypass air channel. The air flow sensor is also called the air flow meter. The specifications of the air flow meter vary with the fuel injection system and the engine. The general requirements for the air flow meter: the air flow meter should have a wide temperature range, a dynamic range and a The flow rate is detected, and under harsh working conditions, the performance change is small, and the pulsating airflow can also be tested. Sensors are electronic devices used in modern automobile gasoline injection systems to control the amount of fuel injected. Installed between the air filter and the throttle body, it is used to measure the amount of air sucked into the engine as a parameter to determine the basic fuel injection amount. On the electronically controlled fuel injection device of the automobile, the air flow sensor is one of the important components that determines the control accuracy of the system. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory.
