Walnut Blaster for Automotive Engine System Intake Pipe Valve Cleaning

The HTS558 Automotive Walnut Sand Carbon Cleaner utilizes high-pressure airflow to propel walnut sand into the engine intake pipe. Inside the enclosed intake pipe, the high-pressure and high-speed sand particles vigorously tumble and collide, effectively dislodging carbon deposits from the intake valve and cylinder wall. Subsequently, the walnut sand and carbon mixture impurities are collected and directed through a specialized connector into the sand storage barrel for recycling, ensuring the efficient return of the carbon mixture for further use.

Walnut powder, also known as walnut sand, is produced by grinding crushed walnut shells into a fine powder after a rigorous selection process. It possesses remarkable anti-pressure and wear-resistant properties. Walnut sand features a multitude of surface pores that grant it exceptional adsorption capabilities. It is non-toxic and corrosion-resistant, demonstrating resistance to dissolution in acids, alkalis, and water. As a pure, natural polishing material, walnut sand boasts a hardness level that falls between that of metals and carbon deposits, allowing it to effectively and thoroughly clean the intake pipe and the back side of the intake valve without causing any damage.

To use the HTS558, the user must first open the head cover, pour in 2-4 kg of walnut powder, press the dust guard on the walnut powder, and then close the cover. Next, the spray gun muzzle and recycle hose are joined together, with a hole on the recycle hose. The intake manifold of the engine is then removed, and the spray gun is plugged into the intake. The crankshaft is turned to close the intake valve, and an air pump (not included) is connected to the HTS558. After connecting the AC power, the cleaning process can begin, typically lasting 1-3 minutes, depending on the degree of carbon deposition. Normally, the walnut powder can be reused 5-10 times.

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 due to insufficient combustion of the gasoline in the cylinder. Carbon buildup will reduce the air-fuel ratio, decrease engine power output, and lead to higher fuel consumption, which can be detrimental to the engine's health. It is recommended to perform engine carbon cleaning after approximately 2 years of use or when you've driven around 4,000 miles (or 4,000 kilometers).

The HTS558 fuel system cleaning tool is specifically designed for cleaning the intake pipe and the back side of the intake valve only. If you need to remove carbon deposits from the injector, throttle valve, or cylinder, other tools like the CT400, CT500, or C100 may be more appropriate. Walnut powder is not included in the package, so it must be obtained from a local market. Additionally, a high-pressure air pump is required, which is not included in the package. Any residual walnut powder in the intake pipe will turn to ashes at high temperatures once the engine is started.
