During the working process of the auto engine, the carbon and black gelatinous particles accumulated in the intake and exhaust valves, intake ports, combustion chambers, fuel injectors, and other positions inside the engine produced by unsaturated olefins and colloids in the fuel at high temperature are called carbon deposition. Carbon deposition will increase vehicle exhaust emissions and reduce engine performance. Sometimes, the falling of carbon particles at the valve position may block the normal opening and closing of the valve, resulting in the deformation of the valve stem. The existence of carbon deposition not only occupies a certain space of the engine, but also easily forms a hot spot (the temperature is easy to suddenly increase) under high temperature, leading to the generation of a second ignition point, causing the preignition detonation of the gasoline engine, and then affecting the working performance and service life of the engine. How to avoid carbon deposition in daily use? 1. Use gasoline with high cleanliness and qualified engine oil. Carbon deposition is mainly formed by the accumulation of impurities in gasoline and engine oil, so the use of clean gasoline and qualified engine oil is also the most effective and reliable preferred way. 2. Try to avoid idling for a long time and driving on congested roads. 3. High speed can be used appropriately when on the highway. 4. Properly use regular and qualified fuel additives. What is Walnut Sand? The raw material of walnut sand is walnut shell, which is made and synthesized through strict screening and classification and multiple processes after the walnut shell is broken. It is a walnut extract and belongs to metal polishing media. It has the characteristics of high hardness, high-pressure resistance and wears resistance, and the surface is microporous. It has strong adsorption and sewage interception ability, no corrosion and no pollution. Walnut shell is a natural and non-chemical raw material, so using walnut sand as abrasive will not damage the surface of the workpiece, and using walnut sand to clean auto carbon deposition will not damage the engine, the cleaning effect is remarkable and the cost is low. Why Choose AUTOOL HTS678 Walnut Sand De-Carbon Cleaner?

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 - 【Adapters for Various Models】The AUTOOL HTS678 Walnut Sand De-Carbon Cleaner is equipped with connectors suitable for various models.
