The functions of a car shark fin include: releasing static electricity, amplifying communication signals, generating turbulence, improving GPS system accuracy, etc. It also serves as an FM radio antenna, GSM communication antenna, and GPS antenna. Applying aerodynamic principles, it effectively eliminates the airflow noise caused by traditional rod antennas, resulting in quieter driving. To enhance vehicle communication signals, BMW specifically developed the shark fin antenna for its series of models. Subsequently, due to the shark fin antenna's elegant appearance, comprehensive functionality, diverse colors, seamless integration with the vehicle body, and its stylish, dynamic, and eye-catching design, it has become highly popular among car owners. Various mid-to-high-end car models in the market have successively adopted shark fin antennas.

What are the reasons for a sudden engine stall in the Magotan?

The reasons for a sudden engine stall in the Magotan are as follows: 1. Circuit failure: This may occur due to low-voltage power interruption during driving, causing the engine to stall. In this case, you should primarily check the ignition and starter switches, as well as the fuse box. A short circuit in the low-voltage circuit can cause intermittent stalling. Inspect the low-voltage circuit to ensure it is functioning normally. 2. Component failure: This issue is usually related to the ignition coil, capacitor, or electronic ignition module. The engine may start initially but stall after a while, then restart and stall again. 3. Fuel system failure: Damage to the fuel pump, fuel line rupture, clogged carburetor fuel inlet, or an empty fuel tank can cause stalling. However, the car may still be able to restart, though with difficulty. 4. Ignition system: Problems with the engine overheating or the anti-knock system can also lead to stalling.
