About QPKING Automotive Engine Intake Pipe Valve Clean

What is carbon deposition? There are some hydrocarbon olefin residues attach on engine intake,cylinder when fuel burn in engine not completely. These residues change into hard black shell in high temperature condition , that called carbon deposition. Why need clean carbon deposition? Carbon deposition will decrease air-fuel ratio, cut down engine output power, increase fuel consumption, engine drastic shake on idle status...all the thing will hurt engine deeply. So normally we should clean carbon deposition after every 40000-50000 kilometer trip. Recommend: 1 Air pump pressure should more than 0.7Mpa (7bar/102PSI) 2 Walnut powder diameter should between 0.4-0.8mm, amount in 2-4KG(4-9LB) 3 Cleaning time between 1-3 minutes How to use? 1 Open head cover of AUTOOL 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 spary gun into intake, turn crankshaft to close intake valve. Connect high pressure air pump((not include)) to HTS558 4 Connect AC power, start clean. The process should last 1-3 minutes(depending on carbon deposition circumstances) 5 Close AUTOOL HTS558, check up cleaning result. Normally, walnut powder can be reuse 5-10 times(depending on carbon deposition circumstances) Package include: 1x AUTOOL HTS558 unit 2x Spray gun 1x Goggles 1x Recycle hose 1x Recycle hose and spray gun connector
