[Working principle]:
The working principle of the car engine expansion kettle is to adjust the pressure of the cooling system through the piston and spring inside the expansion kettle. When the engine is working, the coolant expands due to heat, the pressure increases, and the piston in the expansion kettle moves upward under the pressure, compressing the spring, thereby adjusting the pressure of the cooling system.
Adjust the pressure of the cooling system: effectively adjust the pressure of the cooling system, prevent engine overheating and coolant overflow, and protect the engine.
Improve driving safety: Ensure the normal operation of the engine, improve driving safety, and ensure your driving safety and comfort.
