Q&A
✅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. The valve cleaner 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
Regarding the HTS678 intake valve cleaning machine
- 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.
Regarding the cleaning
- 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 valve cleaner 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.
