Utilizing walnut powder, it provides a thorough yet gentle cleaning to improve engine performance and reduce fuel consumption. The HTS558 ensures your engine consistently delivers \u003cstrong\u003epeak performance\u003c\/strong\u003e .\u003c\/p\u003e\n\u003cp\u003eModern gasoline engines with direct injection are particularly prone to heavy deposit buildup in the intake system. Because the fuel in these engines no longer passes through the intake valves, the cleaning effect of gasoline is absent. Over time, this leads to the formation of hard carbon layers that restrict airflow and reduce engine performance. The AUTOOL HTS558 offers an effective technical solution specifically designed to address this problem.\u003c\/p\u003e\n\u003ch2\u003eTechnical operating principle of the walnut powder blasting process\u003c\/h2\u003e\n\u003ch3\u003eMechanical cleaning without damaging metal surfaces\u003c\/h3\u003e\n\u003cp\u003eWalnut dust blasting is a mechanical cleaning process in which fine granules of ground walnut shells are blasted onto the soiled surfaces using compressed air. The material is hard enough to remove carbon deposits, yet soft enough not to damage sensitive engine components.\u003c\/p\u003e\n\u003ch3\u003eBlasting and extraction system in one operation\u003c\/h3\u003e\n\u003cp\u003eThe AUTOOL HTS558 combines blasting and extraction technology in an integrated system. While the walnut powder is blasted onto the contaminated inlet valves, the dissolved residues are simultaneously extracted and filtered. This keeps the work area clean and allows for partial reuse of the blasting media.\u003c\/p\u003e\n\u003ch3\u003eControlled compressed air operation\u003c\/h3\u003e\n\u003cp\u003eCleaning is carried out via an external compressed air connection. The constant air pressure evenly accelerates the walnut powder and directs it precisely onto the surfaces to be cleaned. This enables controlled and efficient removal of carbon deposits.\u003c\/p\u003e\n\u003ch2\u003eKey features of the AUTOOL HTS558\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cstrong\u003eDeep removal of carbon deposits:\u003c\/strong\u003e Thorough removal of stubborn deposits on intake manifolds and valves that impair engine operation.\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eExternal compressed air connection:\u003c\/strong\u003e Provides powerful pressure for efficient cleaning.\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eBuilt-in dust filter:\u003c\/strong\u003e Separates the walnut powder from carbon deposits for reuse.\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eIntegrated design:\u003c\/strong\u003e Walnut powder is sprayed and recovered simultaneously.\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003e3-year warranty:\u003c\/strong\u003e Reliability and safety for long-term use.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eEfficient recovery system\u003c\/h3\u003e\n\u003cp\u003eA key feature of the AUTOOL HTS558 is its integrated recovery system. During the cleaning process, the walnut dust, along with the loosened deposits, is extracted and separated by a filter. The blasting media can then be reused, significantly reducing material consumption.\u003c\/p\u003e\n\u003ch3\u003eWorkshop-ready construction\u003c\/h3\u003e\n\u003cp\u003eThis device was specifically designed for use in workshops. Its robust construction, stable connections, and durable materials ensure reliable performance in daily operation. Performance remains consistent even with frequent use.\u003c\/p\u003e\n\u003ch2\u003eTypical causes of carbon deposits in the engine\u003c\/h2\u003e\n\u003ch3\u003eDirect injection in modern gasoline engines\u003c\/h3\u003e\n\u003cp\u003eIn engines with gasoline direct injection, the fuel is injected directly into the combustion chamber. As a result, no cleaning fuel components pass through the intake valves. Oil mist from the crankcase ventilation can accumulate there and, over time, lead to heavy carbon deposits.\u003c\/p\u003e\n\u003ch3\u003eShort driving distances and low operating temperatures\u003c\/h3\u003e\n\u003cp\u003eVehicles that are primarily driven on short trips often do not reach their optimal operating temperature. In such cases, unburned fuel residues and oil vapors can accumulate more quickly in the intake manifold and lead to deposits.\u003c\/p\u003e\n\u003ch3\u003eWear-related oil mist formation\u003c\/h3\u003e\n\u003cp\u003eAs mileage increases, many engines produce more oil mist that enters the intake system via the crankcase ventilation. This oil film forms the basis for the formation of carbon deposits on the intake valves.\u003c\/p\u003e\n\u003ch2\u003eWhat are carbon deposits?\u003c\/h2\u003e\n\u003cp\u003eCarbon deposits form when incompletely burned fuel leaves residue in the intake manifolds and cylinders. At high temperatures, this residue hardens into a crust that impairs engine performance. It increases fuel consumption and leads to rough engine running.\u003c\/p\u003e\n\u003ch3\u003eEffects on engine performance\u003c\/h3\u003e\n\u003cp\u003eHeavy deposits can significantly reduce airflow in the intake manifold. This results in less fresh air entering the combustion chamber, leading to incomplete combustion. The engine loses power and responds less responsively to throttle inputs.\u003c\/p\u003e\n\u003ch3\u003eInfluence on exhaust emissions\u003c\/h3\u003e\n\u003cp\u003eImpaired combustion also affects emissions. Vehicles with heavy carbon deposits may exhibit increased emissions and potentially experience problems during emissions testing.\u003c\/p\u003e\n\u003ch2\u003eWhy is cleaning off carbon deposits important?\u003c\/h2\u003e\n\u003cp\u003eCarbon deposits worsen the air-fuel ratio, reduce engine performance, and increase fuel consumption. Regular cleaning (every 40,000 to 50,000 kilometers) ensures smooth engine operation and a longer engine lifespan.\u003c\/p\u003e\n\u003ch3\u003eImproved throttle response\u003c\/h3\u003e\n\u003cp\u003eAfter cleaning the intake valves, the engine can breathe freely again. This leads to improved acceleration and smoother power delivery.\u003c\/p\u003e\n\u003ch3\u003eReduced fuel consumption\u003c\/h3\u003e\n\u003cp\u003eBy restoring optimal airflow, the engine runs more efficiently. In many cases, a slight reduction in fuel consumption can be observed after professional cleaning.\u003c\/p\u003e\n\u003ch2\u003eWhat is walnut powder?\u003c\/h2\u003e\n\u003cp\u003eWalnut powder is a \u003cstrong\u003enatural polishing agent\u003c\/strong\u003e that is harder than carbon deposits but softer than metal. It removes deposits thoroughly without damaging the engine. Walnut powder is practically insoluble in acids, alkalis, and water, making it an ideal cleaning material.\u003c\/p\u003e\n\u003ch3\u003eEcological advantage of the material\u003c\/h3\u003e\n\u003cp\u003eSince walnut shells are a natural byproduct of the food industry, the blasting medium is considered environmentally friendly. Compared to chemical cleaners, it does not leave any aggressive residues.\u003c\/p\u003e\n\u003ch3\u003eOptimal grit size for engine cleaning\u003c\/h3\u003e\n\u003cp\u003eA grit size of approximately 0.4 to 0.8 mm is typically used for cleaning intake valves. This size offers a good balance between cleaning effectiveness and material protection.\u003c\/p\u003e\n\u003ch2\u003eApplication of the AUTOOL HTS558\u003c\/h2\u003e\n\u003col\u003e\n\u003cli\u003eFill the AUTOOL HTS558 with 2-4 kg of walnut powder and close the top cover.\u003c\/li\u003e\n\u003cli\u003eConnect the spray gun to the return hose.\u003c\/li\u003e\n\u003cli\u003eRemove the engine's intake manifold and close the intake valve.\u003c\/li\u003e\n\u003cli\u003eConnect a high-pressure air pump (not included) and start the cleaning process.\u003c\/li\u003e\n\u003cli\u003eCheck the cleaning result and recycle the walnut powder for further use if necessary.\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003ch3\u003ePreparing for engine cleaning\u003c\/h3\u003e\n\u003cp\u003eBefore cleaning begins, the engine should be cooled to ambient temperature. It is also important that the valve to be cleaned is closed to prevent any blasting media from entering the combustion chamber.\u003c\/p\u003e\n\u003ch3\u003eCheck after cleaning\u003c\/h3\u003e\n\u003cp\u003eAfter completing the cleaning process, a visual inspection with an endoscope camera is recommended. This allows you to check whether all deposits have been completely removed.\u003c\/p\u003e\n\u003ch2\u003eRecommended specifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eAir pump pressure: \u0026gt;0.7 MPa (7 bar \/ 102 PSI)\u003c\/li\u003e\n\u003cli\u003eWalnut powder: diameter 0.4-0.8 mm, quantity 2-4 kg\u003c\/li\u003e\n\u003cli\u003eCleaning time: 1-3 minutes per valve\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eOptimal print settings\u003c\/h3\u003e\n\u003cp\u003eStable air pressure is crucial for a uniform spray pattern.
