Hydrogen Engine Carbon Cleaning Services
Non-invasive hydrogen carbon cleaning for petrol, diesel and hybrid cars at our Serangoon Garden, Bukit Batok and Upper Thomson workshops. From $138 nett.
WHAT IS CARBON CLEANING?
What is carbon cleaning and how it can help you
Engine carbon cleaning removes the carbon deposits that form inside an engine – on the valves, pistons and combustion chambers, and in the turbo, EGR and DPF systems. Our hydrogen carbon cleaning machine produces a hydrogen-oxygen gas from a specially formulated potassium hydroxide (KOH) solution, and feeds it into the engine through the air intake while the engine runs.
No engine parts need to be removed for the hydrogen treatment, so the process is non-invasive and suits petrol, diesel and hybrid cars.
WHO NEEDS IT
Vehicles in need of engine carbon clean?
Hybrid CarGenerate more carbon emissions due to frequent start-stop operations.
High Mileage Cars
Idle CarsVehicles that idle for extended periods produce higher carbon emissions and consume more fuel inefficiently.
Noticeable Performance IssuesCars showing signs of reduced fuel efficiency, rough idling, engine knocking, sluggish acceleration, or increased emissions likely have carbon buildup.WE RECOMMEND ONCE A YEAR
How often should I get a carbon clean?
The frequency of carbon cleaning depends on how you want to maintain your vehicle and your driving conditions. You have a few options:
Reactive maintenance
You can wait until the car starts to feel sluggish, noisy, or shows signs of performance loss, such as rough idling, reduced fuel efficiency, or increased emissions. If these symptoms occur, it's a clear indicator that a carbon clean is needed.
Driving conditions-based cleaning
If you drive primarily in urban environments with frequent stop-start traffic or take short trips where the engine doesn’t reach optimal temperature, carbon buildup can occur faster. In these cases, carbon cleaning every 10,000 to 15,000 km may be beneficial to maintain smooth performance.
Preventive maintenance
To prevent issues before they arise, you can incorporate carbon cleaning into your annual service routine. This proactive approach ensures the engine stays in peak condition, reduces the risk of breakdowns, and prolongs the life of key components, such as the EGR valve, DPF, and catalytic converter.
HOW LONG IT TAKES
How long does carbon cleaning take?
From 30 minutes
The carbon cleaning procedure typically requires a minimum of 30 minutes, but the total time can vary depending on the vehicle type and intake system design.
Equipment connection
Connection and disconnection of the equipment can take as little as 2 minutes for vehicles with straightforward engine layouts. However, for more complex systems—such as those found in high-performance or premium models like the Audi C5 RS6, certain BMWs, and Mercedes models—the process can take significantly longer. These vehicles often feature intricate intake systems with multiple components that need careful access, adding to the overall setup time.
What affects the time
- Engine size and design
- Accessibility of the air intake system
- Presence of additional engine covers or protective panels
- Integration with other systems, such as turbochargers or EGR valves
Careful, safe set-up
To ensure optimal results, technicians must carefully connect the equipment without compromising any components, especially in tightly-packed engine bays. Therefore, while the core cleaning itself is efficient, the total time for the procedure can vary from 30 minutes to over an hour for vehicles with more complex configurations.
FYI
Can hydrogen damage the engine?
No, hydrogen does not damage the engine. It is a non-corrosive gas and is harmless to all engine components. Hydrogen only reacts with and removes carbon deposits without affecting metal, rubber, or plastic parts. As long as the procedure is done correctly, it will not degrade or harm any internal engine components beyond exposing pre-existing issues.
