AUTOOL HTS678 Walnut Sand Blaster Cleaner Car Engine Carbon Deposition Cleaning & Walnut Blaster

The AUTOOL HTS678 walnut sand blaster is a car engine carbon deposition cleaning equipment with adjustable output air pressure. The Walnut Blaster uses harmless walnut shell abrasive to deeply clean carbon deposits in the intake manifold and valves, effectively resolving issues such as unstable idle, incomplete fuel combustion, and increased engine oil consumption. The AUTOOL HTS678 walnut blasting machine features a 1800W motor and an adjustable pressure knob, providing strong suction power and flexible air pressure regulation. In addition, it is also equipped with 23 connectors suitable for various vehicle models, therefore meeting the cleaning needs of different workshops.
✅What Is Walnut Sand?

Walnut sand is made from walnut shells, which are processed through strict screening and classification after being broken. It is a walnut extract and serves as a metal polishing medium. Walnut sand has high hardness, high-pressure resistance, and wear resistance, with a microporous surface. It provides strong adsorption and sewage interception ability, and it does not cause corrosion or pollution.

Using walnut sand as an abrasive will not damage the workpiece’s surface or harm the engine when cleaning carbon deposits. Moreover, the cleaning effect is remarkable, and the cost is relatively low.

✅What Is Carbon Deposition?

Some hydrocarbon olefin residues attach to the engine intake and cylinder when the fuel does not burn completely. It residues change into a hard black shell in high-temperature conditions, called carbon deposition.

✅Why Need Clean Carbon Deposition?

Carbon deposition will decrease the air-fuel ratio, cut down engine output power, increase fuel consumption, engine drastic shake on idle status all the thing will hurt the engine deeply. So normally we should clean carbon deposition after every 40000-50000 kilometer trip.

✅Air Compressor Configuration

Air pressure up to 0.7mpa, 6bar or more air pressure.

We recommend using an air compressor equipped with a dryer filter to effectively prevent moisture buildup, which can cause walnut shell media to clump and result in poor blasting performance.

⚠️Walnut Sand Blaster Warm Tips
  • AUTOOL HTS678 walnut sand blaster is a special machine for the engine Intake pipe and intake valve back side.
  • First, close the intake valve. Then, spray walnut powder into the engine intake using an air pump (not included). Meanwhile, the HTS678 walnut blaster will simultaneously recycle the walnut powder through its vacuum system, ensuring an efficient and clean operation.
  • This is a closed loop. The walnut powder will impact carbon deposition on the inner wall of the intake pipe. After thousands of impacts, carbon deposition will be clear thoroughly
  • A chemical cleaning agent will corrode the pipe and shorten the lifetime of the engine.
  • Walnut powder is a pure natural polish material. It shows high performance in hardness, anti-pressure, and wear resistance.
  • Walnut powder hardness was lower than metal but higher than carbon deposition. Take these advantages,
  • AUTOOL HTS678 walnut sand blaster will clean the intake pipe and back side of the intake valve thoroughly but with no damage
  • The high-precision engine system is sensitive to the foreign matter of the intake pipe, such as the BM-W Valvetronic system.
  • That is why we need AUTOOL HTS678 walnut sand blaster to clean the carbon deposition in the intake pipe. AUTOOL HTS678 cleans one intake pipe each time, and the 6-cylinder engine should cleaned 6 times one by one(and so on).
  • AUTOOL HTS678 walnut sand blaster is special for the intake pipe and intake valve back side clean only, if you want to clean carbon deposition on the injector/throttle valve/cylinder, please click here to shop for Injector Cleaners.
  • The package does not include walnut sand and a high-pressure air pump.
  • Walnut powder residual in the intake pipe will go to ashes at a high temperature after the engine starts.

How To Use The AUTOOL HTS678 Walnut Shell Blasting?

  • Step 1: Open the outer package and inspect all parts for any damage.
  • Step 2: Pull the rod upwards, open the metal latches on both sides of the main unit, and swing the accessory box outwards. Take out the accessories, lock the accessory box, and proceed with the component installation as per the steps below.
  • Step 3: Connect the end of the recovery particle hose with the tendon sheath to the main unit. Ensure the tendon sheath is clamped securely and confirm it is locked in place.
  • Step 4: Select the appropriate fitting connector for the engine air intake, either the metal connector or the yellow silicone connector.
  • Step 5: Attach the other end of the recovery pipe to the black transit-bend. Use the large bend with the metal model adapter and the small bend with the yellow silicone model adapter.
  • Step 6: Open the top cover of the main unit. Rotate the handle of the filter cartridge counterclockwise, remove the filter cartridge, and check that the filter screen at the bottom is flat and not rolled over.
  • Step 7: Add walnut sand into the sand storage bucket through the filler opening. The recommended amount is generally 3-5 kg.
  • Step 8: Reinsert the filter cartridge and rotate it clockwise until it locks securely.
  • Step 9: Close and secure the top cover of the main unit.
  • Step 10: Move the main unit to the operating site and connect it to an external compressed air source, ensuring a pressure of no less than 0.7 MPa.
  • Step 11: Switch on the standard mode of the device to start operation. For more advanced control, professionals may activate expert mode. Only one mode switch can be active at a time; the other must be turned off, or the air switch protection will engage.
  • Step 12: Insert the sandblasting gun into the injection port on the black silicone bend of the recovery pipe. Pull the switch on the sandblasting gun to begin the carbon removal procedure. Adjust the throttle valve at the bottom of the gun as needed based on the workpiece and operating conditions to optimize spraying speed.
Tips:
  • Firstly, wear safety goggles during operation to ensure safety. In addition, this will help protect your eyes from debris and any potential hazards.
  • The walnut shell abrasive size should be between 0.6~1.2 mm. Under normal conditions, walnut shell abrasive can be reused 5~10 times.
