Cleaning Cylinder Heads

The cylinder head is one of the most important components in an internal combustion engine, as it houses the valves, intake and exhaust ports, the combustion chamber, and, in some cases, the camshaft. Due to its constant exposure to high temperatures and combustion residues, it is common for carbon deposits, burnt oil, oxides, and other contaminants to accumulate, affecting engine performance.

Cleaning cylinder heads is a critical process in automotive maintenance, and the use of ultrasonic cleaning machines has become the best alternative to traditional methods. This procedure ensures deep removal of contaminants without damaging the surfaces of the component, improving engine performance and prolonging its lifespan.
 

Cleaning Cylinder Heads with Ultrasonic Cleaning Machines

Common Problems in Cylinder Heads and the Need for Deep Cleaning
Cylinder heads can accumulate various types of dirt and contaminants that affect engine performance:

• Carbon deposits: Combustion residues that adhere to the valves and ports, reducing gas flow.
• Oil and grease: Burnt oil buildup that can clog lubrication channels.
• Oxides and coolant deposits: Corrosion in cooling channels affecting heat dissipation.
• Metallic residues: Wear particles that can interfere with the proper sealing of valves and gaskets.

Proper maintenance of the cylinder head is essential to prevent overheating, power loss, and mechanical failures. This is where ultrasonic cleaning stands out as the best option.

Ultrasonic Cylinder Head Cleaning: How Does It Work? - Engine head

Ultrasonic cleaning is an advanced process that uses high-frequency sound waves to generate cavitation in a cleaning liquid. This phenomenon creates microbubbles that implode and detach dirt from the surface without damaging the material.

Steps of the Ultrasonic Cleaning Process
1. Disassembly and Pre-Inspection

• Components such as spark plugs, injectors, and gaskets are removed for more efficient cleaning.
• The cylinder head is inspected for damage or excessive wear.

2. Preparation of the Ultrasonic Tank

• It is filled with a specialized cleaning solution to remove grease, carbon deposits, and oxides without affecting aluminum or other metals.

3. Submerging the Cylinder Head in the Ultrasonic Machine

• The cylinder head is completely immersed in the cleaning tank.
• Ultrasonic waves are applied, generating cavitation in the liquid.
• The imploding bubbles remove contaminants from all cavities and channels.

4. Rinsing and Drying

• Residual cleaning solution is removed with a high-pressure rinse.
• The cylinder head is dried to prevent oxidation.

5. Final Inspection and Reassembly

• The cleanliness of the channels and surfaces is checked.
• Removed components are reinstalled, and functionality is verified.

 

Advantages of Ultrasonic Cylinder Head Cleaning - Engine head

Deep and Uniform Cleaning
Ultrasonic cavitation reaches even the most inaccessible areas, ensuring total cleanliness.

Effective Removal of Carbon Deposits and Oils
Dissolves residues without the need for aggressive manual intervention.

Preservation of Material Properties
