What is carbon deposition?

There are some hydrocarbon olefin residues attached to the engine intake, cylinder when the fuel burns in the engine not 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.

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

How To Use

• 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)

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.
• Walnut powder is not included in the package, please get it in the local market.
• High-pressure air pump is required (not included in the package).
• Walnut powder residual in the intake pipe will go to ashes at a high temperature after the engine starts.
