AUTOOL HTS558 Car Engine Carbon Deposition Cleaner Intake Pipe Valve Cleaning Machine Decarbonizing

Carbon deposition is a common issue in modern engines, leading to reduced performance, increased fuel consumption, and engine damage. The AUTOOL HTS558 is a specialized machine designed to tackle this problem efficiently using walnut sand grit, ensuring thorough cleaning without damaging engine components.

What Is Carbon Deposition?

Understanding Carbon Buildup

Carbon deposition occurs when hydrocarbon residues from incomplete fuel combustion accumulate on engine parts like the intake manifold, valves, and cylinders. Over time, these residues harden into a black, sticky shell due to high temperatures, impairing engine performance.

Why Clean Carbon Deposition?

• Reduced air-fuel ratio: Decreases engine efficiency.
• Lower output power: Impacts acceleration and performance.
• Increased fuel consumption: Leads to higher running costs.
• Engine shaking at idle: Causes discomfort and potential long-term damage.

Regular cleaning every 40,000–50,000 kilometers is recommended to maintain optimal engine health.

Features of AUTOOL HTS558

1. Deep Carbon Deposit Removal

The HTS558 deeply cleans highly sticky carbon deposits from the intake manifold, intake valves, and exhaust valves, resolving issues like:

• Unstable idling
• Insufficient fuel combustion
• Reduced air-fuel ratio

2. External Air Source

An external high-pressure air pump (not included) powers the walnut sand grit, ensuring powerful and efficient carbon removal.

3. Built-in Dust Filter

The integrated filter separates and recycles walnut sand grit, making the process eco-friendly and cost-effective.

4. Integrated Spray & Recovery Design

The machine sprays and recovers walnut sand grit simultaneously, creating a closed-loop system for maximum efficiency.

5. 3-Year Warranty

AUTOOL offers a 3-year warranty for non-human damage, with free replacement parts.

Why Use Walnut Sand Grit?

Natural and Effective Cleaning

• Non-toxic and corrosion-resistant: Safe for engine components.
• High hardness: Stronger than carbon deposits but gentler than metal.
• Superior adsorption: Porous surface ensures thorough cleaning.

Chemical-Free Solution

Unlike chemical cleaners, walnut sand grit does not corrode engine parts, ensuring longevity.

How to Use AUTOOL HTS558

Step-by-Step Guide

1. Prepare the Machine

   • Open the head cover and pour 2–4 kg of walnut sand grit.
   • Secure the dust guard and close the cover.

2. Connect the Spray Gun & Hose

   • Attach the spray gun muzzle to the recycle hose (with a hole for airflow).

3. Prepare the Engine

   • Remove the intake manifold.
   • Plug the spray gun into the intake and close the intake valve by turning the crankshaft.
   • Connect a high-pressure air pump (≥ 0.7 MPa / 7 bar / 102 PSI).

4. Start Cleaning

   • Connect to AC power and run the machine for 1–3 minutes (adjust based on carbon buildup).

5. Inspect & Reuse

   • Check the cleaning results.
   • Walnut sand grit can be reused 5–10 times.

Recommended Specifications

• Air pump pressure: ≥ 0.7 MPa (7 bar / 102 PSI).
• Walnut sand grit size: 0.4–0.8 mm diameter.
• Cleaning time: 1–3 minutes per intake pipe.

Why Choose AUTOOL HTS558?

Precision Cleaning for High-Performance Engines

• Ideal for BMW Valvetronic and other sensitive systems.
• Cleans one intake pipe at a time (e.g., 6 pipes for a 6-cylinder engine).

Specialized for Intake Systems

For cleaning injectors, throttle valves, or cylinders, consider AUTOOL’s CT150, CT200, or C100 models.

Eco-Friendly & Cost-Effective

• Walnut sand grit burns away harmlessly in high temperatures.
• Reusable material reduces waste.
