In today's automotive world, the air flow meter plays a crucial role. It is an indispensable part of the automobile engine management system and has a profound impact on the performance of the engine.
The main function of the air flow meter is to accurately measure the amount of air entering the engine. This data is crucial for the proper operation and performance optimization of the engine. In the fuel injection system of automobile, the air quantity information provided by air flow meter is one of the key bases to determine the fuel injection quantity. Only when the amount of air entering the engine is accurately mastered, can the appropriate fuel and air mixture ratio be achieved to ensure the efficient combustion of the engine.
The air flow meter also has a key impact on the dynamic performance of the engine. A malfunctioning air flow meter or inaccurate measurement may result in an imbalance in the fuel-air mix ratio. When the air volume measurement value is low, it will lead to too much fuel injection, too strong mixture, and the engine may have problems such as power decline, fuel consumption increase, and exhaust emissions exceed the standard. On the contrary, if the air volume measurement is high, the fuel injection is too little, and the mixture is too thin, the engine may shake, accelerate and even stall.
In the acceleration process of the car, the air flow meter plays an important role. As the driver presses down on the accelerator pedal, the amount of air entering the engine increases rapidly, and the air flow meter is able to quickly sense this change and relay accurate information about the amount of air to the ECU. The ECU then adjusts the fuel injection so that the engine produces enough power to meet the acceleration needs.
