BPV Valve

is a mechanical component used in supercharging systems of internal combustion engines. Its main task is to remove excess air pressure from the system, thus protecting the engine from damage1. This works especially important in the case of a turbocharger, where excess pressure can lead to various problems.
The basic principle of the BPV valve is to open and release excess air pressure when the pressure in the system exceeds a certain set level. When the driver releases the gas, the BPV valve opens, allowing excess air to escape. This prevents overloading, which could lead to damage to the turbocharger or other system components.

Functions of the BPV valve in the supercharging system:

  1. Turbocharger protection: The BPV valve protects the turbocharger from excessive pressure. By releasing excess air in a controlled manner, it effectively eliminates the risk of damage to the rotor, which contributes to the longevity of this key system component.
  2. Maintaining smooth operation: The BPV valve actively promotes smooth operation of the supercharging system. By quickly releasing excess air at times when shifting gears or releasing the gas, it eliminates the delay in engine response known as "turbo-lag."
  3. Overload prevention: This component effectively protects the supercharging system from overloads by controlling air pressure. This minimizes the risk of damage to other components, such as the intercooler and connecting tubes.
  4. Optimizing efficiency: A key aspect of the BPV valve is its effect on engine efficiency. Reducing excess pressure not only translates into fuel savings, but also increased power, an important criterion for users seeking an economical and efficient solution.

BPV valve remanufacturing process:

  1. Diagnosis: Qualified technicians perform a thorough diagnosis to determine the source of the BPV valve problem.
  2. Disassembly: Once the diagnosis is made and it is determined that the cause of the abnormality is a fault in the BPV valve, the component is disassembled.
  3. Repair or replacement of parts: if BPV valve parts are damaged or worn out, technicians replace them with new or remanufactured parts.
  4. Cleaning and adjustment: If the valve parts are in good condition, technicians thoroughly clean and adjust them to restore the original performance.
  5. Testing: After repair, all valves are thoroughly tested to make sure they function according to original specifications.
