advantage：

Walnut sand cleaning is the best cleaning method in 4S shops. The carbon deposit is impacted, and then the walnut sand and the carbon deposit mixture are recycled to the dust collector through the perfect joint. By cleaning and removing carbon deposits, it can reduce fuel consumption, reduce noise, reduce exhaust gas, and improve power. Quickly remove carbon deposits on the engine intake valve, cold car shaking, weak acceleration, excessive fuel consumption, knocking and knocking on the cylinder, and excessive exhaust emissions. Such faults can be solved, and the effect is immediate!

theory：

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, high efficiency, etc. The surface is porous with strong adsorption and pollution interception ability. , non-corrosive, safe, 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. Using walnut sand to wash away carbon deposits will not damage the engine and has obvious effects.
