Crash walnut shell into powder, after a vigorous selection process then we get walnut sand.It show high performance in the three area: hardness, anti-pressure, wear-resisting.A large amount of pores on surface of walnut sand which provide super adsorption capacity, non-toxic and corrosion preventive. What is carbon deposition? Carbon deposit is the black gel caused by the repeated high temperature of the engine running, which is the residual rubber in the fuel injector, the throttle valve, the spark plug, and other components caused by insufficient combustion of the gasoline in the cylinder. Why need to clean carbon deposition? Carbon deposition will decrease the air-fuel ratio, cut down engine output power, and increase fuel consumption. All of them will damage the engine deeply. Generally, we need to clean the engine carbon after running for 2 years or driving to 4W kilometers. By removing the throttle, a carbon deposit can be seen clearly.
