Cleaning intake and exhaust channels with walnut shell is a unique and effective way to remove carbon deposits and dirt that accumulate in the car’s intake and exhaust system. Modern engines, especially those with direct injection systems, are prone to build-ups that impair engine performance and reduce efficiency. Crushed walnut shell has gained wide recognition for being eco-friendly and safe for engine parts. Let’s take a closer look at how and why this cleaning method is used and the benefits it offers.
Why is engine channel cleaning necessary?
Over time, carbon deposits build up in the intake and exhaust channels, leading to several problems:
- Power loss. Dirty channels restrict airflow, reducing combustion efficiency.
- Increased fuel consumption. Deposits interfere with proper intake operation, causing the engine to consume more fuel.
- Vibrations and knocking. Dirt in exhaust channels may cause unstable operation and unusual sounds.
- Shortened engine life. Persistent contaminants accelerate wear on engine components.
Regular cleaning helps avoid these issues, maintaining the engine in optimal condition and extending its lifespan.
Why use walnut shell?
Crushed walnut shell has become a popular cleaning agent due to its unique properties:
- Gentle and eco-friendly. Walnut shell is soft enough not to damage metal surfaces but hard enough to effectively remove grime.
- Safe for engine components. Unlike chemical compounds, walnut shell doesn’t cause corrosion or harm metal parts.
- High effectiveness. Thanks to its texture and density, crushed walnut shell removes even old deposits without leaving traces or damaging internal elements.
How is channel cleaning with walnut shell performed?
The procedure requires special equipment and is carried out by skilled professionals to ensure optimal results:
- Engine preparation. Diagnostics is performed to determine the level of contamination in the channels.
- Isolation and protection. All parts not requiring cleaning are isolated and protected to prevent particle infiltration.
- Connecting equipment. Special equipment injects finely crushed walnut shell at high pressure.
- Cleaning process. The walnut shell effectively removes carbon deposits from the intake and exhaust channels.
- Quality control and testing. After cleaning, channels are inspected, and the engine undergoes a test run.
Benefits of walnut shell cleaning
Using walnut shell for channel cleaning provides several advantages:
- Eco-friendliness. The process does not require aggressive chemicals, and walnut shell is a natural material that is safe for the environment.
- Lasting effect. After cleaning, the engine runs more smoothly, fuel consumption decreases, and power is restored.
- No damage. The softness of the material preserves the integrity of all cleaned surfaces.
When should intake and exhaust channels be cleaned?
Cleaning is recommended every 30,000–50,000 kilometers, depending on the vehicle’s operating conditions. If you notice a decrease in power, increased fuel consumption, or unusual engine sounds, it might be time for a cleaning.
