AUTOOL HTS558 walnut powder engine cleaner machine is advanced equipment for cleaning engine intake carbon deposition. Keeping the engine in healthy status, make sure the engine provides high-quality power constantly.

What is walnut powder sand?
The raw material of walnut grit is walnut shell, a natural, non-chemical raw material, which is crushed and synthesized after strict screening as well as made in multiple processes. It is a walnut extract as an abrasive, used in metal polishing media will not damage the surface of the workpiece. It is characterized by hardness, compressive strength, abrasion resistance, and has a strong adsorption, no corrosion, no pollution. Using walnut grit to clean carbon buildup in cars won't damage the engine, is safe and efficient, and saves you money at the same time.
 
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.

Automotive decarbonization cleaning expert
Carbon buildup leads to erratic engine idling, lack of air intake, cutoffs, and weak acceleration.HTS558 can help you effectively clean carbon buildup and restore your car to a healthy engine condition.
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.
Integrated design
The walnut sand grit can be sprayed and recovered simultaneously.
Built-in dust filter
It can separate the recovered walnut sand grit from carbon deposits for recycling.
How To Use the AUTOOL HTS558?
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)
