As a maintenance technician, do you often encounter vehicle owners who frequently report that their vehicles are losing power, shaking at idle, or consuming more fuel? Even when it is known that the problem is caused by carbon deposits, an efficient and convenient cleaning solution is often unavailable. Traditional chemical cleaning fluids are limited in effectiveness and work slowly, and can no longer meet the professional demands of today’s automotive service market. Without specialized equipment, carbon deposit cleaning is difficult to perform to high standards. It is time-consuming, often incomplete, and can even affect customer satisfaction and repeat business.
The AUTOOL HTS728 features a patented walnut shell abrasive blasting design that uses the mechanical principles of physical abrasion and high-speed impact to efficiently remove carbon deposits inside the engine, making it especially suitable for GDI and turbocharged vehicles. The equipment uses high-pressure airflow to spray natural walnut shell abrasives, 0.4–0.6 mm in diameter, onto the combustion chamber, intake valves, and exhaust valves. This physical cleaning method not only effectively avoids the risk of chemical corrosion but also keeps the wear rate of aluminum components below 0.01 μm per use. A single cleaning can last 30,000–50,000 km, with a total cost of only one-fifth that of traditional disassembly cleaning. Equipped with a built-in HEPA filter and mesh, the equipment effectively separates the walnut shell abrasives from the carbon deposits for reuse. This design not only improves cleaning efficiency but also ensures environmental friendliness and cost-effectiveness, making it a high-performance, eco-friendly professional cleaning solution.
Key Features and Functions:
Natural Physical Cleaning
The AUTOOL HTS728 uses 0.4–0.6 mm natural walnut shell abrasives with moderate hardness, ensuring residue-free cleaning. Utilizing the mechanical principles of physical abrasion and high-speed impact, it efficiently removes carbon deposits inside the engine. This method not only avoids the risk of chemical corrosion but also causes no damage to metal components, delivering results far superior to those of traditional chemical cleaning fluids or wire brush methods.
Dual-Mode Blasting Nozzle Handle
The AUTOOL HTS728 handle features both blasting and air modes. The blasting mode deeply removes stubborn carbon deposits, while the air mode effectively clears residual abrasives and debris, quickly improving cleaning quality and preventing residue from entering the engine and causing damage.
High-Power Motor
The AUTOOL HTS728 is equipped with a 1400W high-power motor, providing strong and stable suction. Whether removing stubborn carbon deposits or recovering walnut shell abrasives and debris, it delivers fast, efficient, smooth, and residue-free operation.
Efficient Recycling & Reusing
The AUTOOL HTS728 features a built-in HEPA filter and mesh, which effectively separate walnut shell abrasives from carbon deposits during cleaning for reuse. This not only reduces waste but also significantly lowers operating costs.
Efficient Carbon Deposit Removal
The AUTOOL HTS728 employs a patented walnut shell abrasive blasting design that, compared to conventional structures, provides comprehensive improvements in performance, safety, and user experience. During operation, the walnut shell abrasives are sprayed more concentratively and evenly, making it particularly suitable for cleaning the complex combustion chamber structures of GDI engines.
5 Blasting Nozzles
The AUTOOL HTS728 is equipped with seven specialized blasting nozzles for different spray angles. Without extensive disassembly, they can be inserted directly through the spark plug hole to reach the top of the pistons, combustion chamber, intake valves, and exhaust valves for blasting operations, avoiding the risks of mechanical damage and seal failure associated with repeated disassembly.
Multifunctional Control Panel
The AUTOOL HTS728 is equipped with a multifunctional control panel integrating status indicators, filling mode, recovery mode, and pressure adjustment. Its intuitive interface allows flexible pressure control, enabling more precise, safe, and efficient operation.
Wide Vehicle Compatibility
The AUTOOL HTS728 comes with 5 adapters of different shapes to meet the cleaning needs of most vehicle models. It is widely compatible with GDI and turbocharged engines from mainstream brands such as BMW, Audi, and Mercedes-Benz, offering strong adaptability and high practicality.
TPR Silent Casters
The AUTOOL HTS728 is equipped with upgraded TPR silent rear casters, providing quiet, wear-resistant performance and smooth, effortless movement, allowing easy maneuvering alongside different vehicles for efficient carbon deposit cleaning.
Product Details
Combination Lock Storage Box: Secure and anti-loss, capable of storing accessories like the recovery hose and safety goggles.
Ergonomic Handle: The surface is treated with a dip-coating process, providing a comfortable grip for effortless pushing and pulling.
Side Hook Design: Convenient access for easy hanging of recovery hoses.
The AUTOOL HTS728 combines multiple functions and design features, making it a specialized walnut shell abrasive de-carbon cleaner for the piston tops, combustion chamber, intake valves, and exhaust valves of automotive engines. Compared to traditional chemical cleaning or manual disassembly methods, the HTS728 is easier and more efficient to operate. Thanks to its patented walnut shell abrasive blasting design, routine carbon deposit cleaning takes only 1–3 minutes, significantly reducing cleaning time and improving work efficiency, making it an ideal tool for maintenance technicians.
