FAQ
What is H2CCM?
H2CCM (Hydrogen Carbon Clean Motor) is a company specialising in the decarbonisation of combustion engines using an innovative hydrogen-based process. Our mission: to restore performance, reduce fuel consumption and limit pollutant emissions.
What is calamine and why is it a problem?
Calamine is soot produced by fuel combustion. It accumulates in cylinders, pistons, valves, EGR valves, turbochargers, etc.
Consequences: loss of power, excessive fuel consumption, premature wear and polluting emissions. It is a bit like the ‘cholesterol’ of your engine.
How does hydrogen decarbonisation work?
We inject a mixture of H₂/O₂ into the engine’s air circuit. Under the effect of heat, carbon deposits are dissolved by pyrolysis and evacuated through the exhaust.
✅ No dismantling
✅ No chemicals
✅ Quick intervention
What are the benefits of H2CCM treatment?
🔧 Restored performance: power, torque and flexibility regained
💸 Fuel economy: 6% to 15% reduction
🌍 Less pollution: lower pollutant and CO₂ emissions
⏱ Prevention: controlled wear and tear and breakdowns avoided
What types of engines can be treated?
All petrol and diesel combustion engines, from 500cc to 75,000cc:
- Passenger cars
- Heavy goods vehicles & commercial vehicles
- Construction & agricultural machinery
- Generators
- Boats & motorcycles
- Military or specialised vehicles
Where do the procedures take place?
Our teams operate:
- In our workshop
- Directly on site for fleets and businesses
How long does treatment last?
Depending on the type of engine, an intervention takes between 45 and 180 minutes, depending on the engine capacity.
What are the benefits for professionals?
For fleets of lorries, construction machinery, generators or boats:
- Lower fuel consumption
- More reliable and durable engines
- On-site servicing to minimise downtime
- Promotion of the company’s CSR policy
Is the manufacturer’s warranty still valid?
Yes ✅ The H2CCM process is 100% mechanical and environmentally friendly, with no chemicals added, and requires no dismantling. The manufacturer’s warranty therefore remains valid.
What is the difference between this and other engine cleaning solutions?
Many attempts have been made, but they lack efficiency or technical control.
Our technology ensures:
- Optimal hydrogen efficiency
- Humidity control, guaranteeing the durability of the treatment
