What does the Chinese translation of car MAP mean?
2 Answers
MAP in cars stands for Manifold-Absolute-Pressure, which translates to "intake manifold absolute pressure" in Chinese, commonly referred to as the intake pressure sensor. Below is more information about the intake pressure sensor: 1. It connects to the intake manifold via a vacuum tube, sensing changes in vacuum within the intake manifold as the engine operates at different speeds and loads. These changes are then converted into voltage signals through alterations in the sensor's internal resistance, providing the ECU with data to adjust fuel injection and ignition timing. 2. The intake pressure sensor measures intake air volume indirectly, a method influenced by various factors, leading to differences in detection and maintenance compared to direct airflow measurement sensors.
Last time my friend just bought a car and asked me this question, I thought it was some high-tech feature. Later I figured out that there are three most common scenarios when people talk about MAP in cars. The first one is the electronic map we use for navigation. You can press the MAP button on the center console or steering wheel to bring up the route. The second one is the air filter in the engine, whose full name is the intake manifold, responsible for evenly distributing air to each cylinder. The third one is used in some older cars, referring to the maintenance manual or fault code diagram. If you see a MAP label in your car, it most likely refers to the navigation map function, which is especially convenient for long-distance driving. However, the specific meaning depends on the button's location, so it's recommended to check your car's manual.
