HTS558 is a de-carbon device for intake valve cleaning, whose working principle is to blast the walnut media into the intake valve through high-pressure airflow. Walnut powder engine Intake pipe valve clean machine is a advanced equipment for clean engine intake carbon deposition.

1. Open head cover of HTS558 and pour into walnut powder (need 2- 4KG ), press dust guard on walnut powder then close cover.

2. Join spary gun muzzle and recycle hose together (there is a hole on recycle hose)

3. Remove intake manifold of engine, plug spray gun into intake,

turn crankshaft to close intake valve. Connect high pressure air pump to HTS558

4. Connect AC power, start clean. The process should last 1-3 minutes

5. Close HTS558, check up cleaning result. Normally, walnut powder can be reuse 5-10 times.

HTS558 Car Engine Carbon Deposition Cleaner Feature：Deep removal of carbon deposits, external air source, built-in dust filter, integrated design. It can deeply remove the sticky carbon deposits on the intake manifold, intake valve and exhaust valve.

Crash walnut shell into powder, after a vigorous selection process then get walnut sand. Anti-pressure, wear-resisting.

A large amount of pores on surface of walnut sand which provide super adsorption capacity, non-toxic and corrosion preventive. It was hardly dissolved in acid, alkali and water.

Walnut sand is a pure natural polish material, its hardness was lower than metal but higher than carbon deposition, it will clean intake pipe and back side of intake valve thoroughly but no damage.
