## Description

Automotive Engine Intake Pipe Valve Clean Machine Valvetronic System Walnut Powder Sand Carbon Deposits Cleaner AUTO Fuel Cleaning Tools

## Features

- 【Why Do You Need It?】Carbon deposits are residues produced by incomplete combustion of unsaturated olefins and colloids in engine oil and fuel at high temperatures during engine operation. Scorched substances, called "carbon deposits", what happens to the engine after severe carbon deposits? 1. The engine is difficult to start cold and shakes at idle speed. 2. The power of the engine decreases, and it is difficult to accelerate. 3. The fuel consumption of the engine increases. 4. The emission of exhaust pollutants increases.
- 【Integrated Design】Walnut sand can be sprayed and recycled simultaneously. Built-in dust filter can separate the recovered walnut sand grit from carbon deposits for recycling. Walnut sand residual in intake pipe will go to ashes at high temperature after engine cranking to avoid damaging automotive exhaust systems & parts.
- 【Safe and Efficient】The raw material of walnut sand is walnut shell. After the walnut shell is crushed, it is made through strict screening and classification and multi-process refining. It has the advantages of high hardness, high pressure resistance, wear resistance, etc. It has the ability of adsorption and interception, is not corrosive, non-toxic, and has low solubility in acid, alkali and water. Walnut shell is an organic and natural tumbler material, not a chemical material. Using it as abrasive will not damage the surface of the workpiece. Walnut powder hardness was lower than metal but higher than carbon deposition. The effect is very obvious.
- 【How To Use?】Shut down the engine before cleaning, then turn the crankshaft to close the intake valve. AUTOOL HTS678 Clean one intake pipe each time, 6 cylinder engines should be cleaned 6 times one by one (and so on), Walnut powder not include in package, please get it in local market

There are many types of connectors with round, oval, rectangular, square, etc. with rich interfaces, including Volvo, BMW, Mercedes Benz, etc.it is a leading auto carbon deposition cleaning expert and an ideal choice for carbon deposition cleaning.
