AUTOOL HTS558 Walnut Shell Sand BlasterCarbon Deposition Engine Cleaner Intake Pipe Valve Decarbon Cleaner Automotive Decarbon Machine

AUTOOL HTS558 walnut blaster features a 1200W motor that provides strong suction power, using physically harmless walnut shells for cleaning. It separates carbon deposits from the walnut shells through a filter, ensuring the shells are reusable. An external air compressor provides powerful sandblasting effects, effectively cleaning the intake manifold and valves, and helping the engine restore optimal performance.

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. The cleaning effect is remarkable, and the cost is 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.

Warm Tips

AUTOOL HTS558 is a special machine for the engine Intake pipe and intake valve back side.
Close the intake valve, then spray walnut powder into the engine intake via air pump(not included), meanwhile, HTS558 will recycle walnut powder by vacuum.
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 HTS558 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 HTS558 to clean the carbon deposition in the intake pipe. The engine should be closed before cleaning, then turn the crankshaft to close the intake valve. AUTOOL HTS558 cleans one intake pipe each time, and the 6-cylinder engine should cleaned 6 times one by one(and so on).
AUTOOL HTS558 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
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.

AUTOOL HTS558 Walnut Blaster Features

Deep removal of carbon deposits: Deeply removes the highly sticky carbon deposits on the intake manifold, intake & exhaust valves. （Solve the problems of unstable idling, insufficient fuel combustion, and reduced air-fuel ratio.
External air source: This enables the walnut sand grit to strike the carbon deposits more powerfully and efficiently.
Built-in dust filter: It can separate the recovered walnut sand grit from carbon deposits for recycling.
Integrated design: The walnut sand grit can be sprayed and recovered simultaneously.
Multiple adapters: Equipped with 5 kinds of adapters
3-year warranty: For damage caused by non-human factors, we promise to resend parts for free within 3 years.

How To Use the AUTOOL HTS558 Walnut Blaster?

Step 1: Open the headcover of AUTOOL HTS558 and pour it into walnut powder (need 2- 4KG ), press dust guard on walnut powder then close the cover.
Step 2: Join the spray gun muzzle and recycle the hose together. (there is a hole in the recycle hose)
Step 3: Remove the intake manifold of the engine, plug the spray gun into the intake, and turn the crankshaft to close the intake valve. Then connect the high-pressure air pump((not included)) to HTS558.
Step 4: Connect AC power, and start clean. The process should last 1-3 minutes. (depending on carbon deposition circumstances)
Step 5: Close AUTOOL HTS558, and check the cleaning result. Normally the walnut powder can be reused 5-10 times. (depending on carbon deposition circumstances)
