Carbon Deposit Removal
Removes carbon deposits from engine, fuel and turbo parts using heated cavitation and appropriate chemistry.
Overview
Where carbon builds up
Carbon is hard and oil-bound.
Carbon deposits form on pistons, cylinder heads, valves, injectors, turbo parts and fuel-system components, often bound with oil and varnish. Heated ultrasonic cavitation lifts these deposits from recessed areas and passages without aggressive scraping that can damage machined surfaces.
A heated heated ultrasonic cleaner or lifting-platform cleaner is used with appropriate chemistry. The application is described in detail for automotive parts cleaning.
Process Considerations
Carbon-removal decisions
Carbon type and part geometry drive the cycle.
Soft soot, hard baked carbon and varnish require different temperature and time.
- Soot and soft carbon
- Hard baked carbon
- Varnish and lacquer
Warm baths and suitable detergent soften and lift carbon; the combination is validated for the material.
- Elevated temperature
- Carbon-removal chemistry
- Controlled exposure
Cavitation reaches combustion chamber features, injector parts and small holes.
- Valves and piston features
- Injector components
- Turbo and housings
Rinsing removes loosened carbon, followed by inspection of recessed areas.
- Particulate rinse
- Visual inspection
- Drying before assembly

Planning the application
Yes. Heated cavitation with carbon-removal chemistry lifts soot and baked carbon from pistons, heads and valves; very hard carbon may need a pre-soak.
It varies with deposit hardness and part geometry; a validated trial cycle sets the production time.
With controlled chemistry and temperature, aluminum components can be cleaned safely; the process is validated for the alloy first.
