What does the Chinese translation of car MAP mean?

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.

In the auto repair world, MAP generally refers to a mechanical component officially called the intake manifold. This part on the engine resembles a branched pipe system that evenly distributes fresh air to each cylinder. Air and fuel pre-mix in the manifold before entering the cylinders for combustion. Many modern vehicles have eliminated this design in favor of direct injection technology. However, older models still feature metal or plastic manifolds - cracks in them can cause power loss and skyrocketing fuel consumption. Last month, my colleague's car had weak acceleration, and after extensive troubleshooting, we found the issue was a leaking intake manifold gasket due to aging. Replacing it immediately solved the problem.

Nowadays, the most commonly used feature among young car owners is the navigation map function. In my Hyundai, there's a prominent MAP touch button on the center console screen. Tapping it allows switching between three view modes: the flat road map is the most practical, capable of predicting traffic congestion; the satellite real-view map is great for locating landmark buildings; and there's also that 3D mode which looks cool but is actually a bit dazzling. The system updates map data monthly, so even new highway ramps are displayed promptly. Last week when I drove to a neighboring city through unfamiliar routes, I kept the voice navigation on the whole time—it even alerted me to details like 'right lane closed 500 meters ahead.' Although smartphones can also navigate, the car's built-in map has a larger screen and more precise route calculations.
