What is the Chinese meaning of car MAP?

[Tonya]

MAP refers to the intake manifold absolute pressure sensor, which indirectly detects the engine's intake air volume. Below is relevant information: 1. MAP refers to the intake manifold absolute pressure sensor, which indirectly detects the engine's intake air volume. Its signal serves as one of the crucial signals for controlling the engine's basic fuel injection quantity. Damage to it or inaccuracy in its data will significantly impact the performance of the car engine. 2. The intake manifold absolute pressure sensor, abbreviated as MAP. It connects to the intake manifold via a vacuum tube. As the engine's speed and load vary, it senses the vacuum changes within the intake manifold, then converts the changes in internal resistance into voltage signals for the ECU to adjust fuel injection quantity and ignition timing. 3. There are various types of intake pressure sensors, including piezoresistive and capacitive types. Due to advantages such as fast response time and high detection accuracy, piezoresistive sensors are widely used in D-type injection systems. The intake pressure sensor detects the absolute pressure in the intake manifold behind the throttle. Based on the engine's speed and load, it detects changes in the absolute pressure within the manifold, converts these into signal voltage, and sends it to the engine control unit (ECU). The ECU then controls the basic fuel injection quantity based on the magnitude of this signal voltage.
