Wenzhou Guoda Electric Co., Ltd. discovered that an automobile air flow meter is used in a modern automobile gasoline injection system and is installed between an air cleaner and a throttle body. It is used to determine the amount of air drawn into the engine as a basic spray. The amount of oil parameters. Hot-wire air flowmeters can be classified into two types, the mainstream measurement method and the bypass measurement method, depending on the installation location of the platinum hot wire.
Hot-wire and hot-film air flowmeters have a fast response time and can reflect changes in air flow within a few milliseconds, so its measurement accuracy is not affected by the pulsation of the intake air flow. In particular, when the engine is under heavy load and low speed, the inlet air flow pulsation is large. Because of the use of a hot wire or hot film air flow meter to measure the intake air volume, the air is measured accurately, and the best air-fuel ratio can be guaranteed under any operating conditions. , The engine's starting performance and acceleration performance are good.
The hot wire of the mainstream air flow meter is a platinum wire with a diameter of 70 μm. It is installed in the sampling tube and the sampling tube is installed in the center of the main air intake. The bypass hot air flowmeter platinum wire is wound on the ceramic spiral tube, installed in the bypass air channel. Air flow sensors, also known as air flow meters, air flow meter specifications vary with the fuel injection system and the engine, the general requirements of the air flow meter: air flow meter should have a wide temperature range, dynamic range and the quality of the The flow rate is measured, and under severe operating conditions, the performance changes are small and the pulsating air flow can also be tested. The sensor is an electronic device for controlling the amount of fuel injected in a modern automobile gasoline injection system. Installed between the air cleaner and the throttle body, it is used to determine how much air is drawn into the engine as a parameter to determine the basic fuel injection. In automotive electronically controlled fuel injection devices, the air flow sensor is one of the important components that determine the system control accuracy.
