H2E Carbon Cleaning Machines

In the car world, few things can affect engine performance like carbon build-up. Deposits build up inside the engine over the years – on the valves, in the combustion chamber and even in the turbines – and affect the power, fuel consumption and even the reliability of the vehicle itself.

For over 15 years, the H2E interdisciplinary team has explored how electrolysis can be applied in the automotive sector.

A patented solution was created to generate an ideal volume and composition of gas suitable for all internal combustion (IC) engines. H2E is the sole method, scientifically verified and entirely safe, for using hydrogen and oxygen gas in IC engine treatment.

Large Electrolyzer in a Compact Housing

H2E treatment uses ionized hydrogen and oxygen in a gaseous state. The gas is obtained with higher voltage and lower current per surface area, unlike all known solutions on the market. That’s why H2E cleans more efficiently and creates a DLC nano-film that reduces friction in the cylinder.

As illustrated in the image below, our competition uses a large box with a smaller electrolyzer (machine to the right), while the ratio of useful electrode surface area to housing volume in our machines is 10x better. Simply put, our electrolyzer is much bigger, which translates into larger cleaning capacity, stability, and consistency.

What H2E Engine Carbon Cleaning Actually Does?

H2E engine carbon cleaning works inside the combustion space, where carbon deposits form naturally during engine operation.

The treatment:

reduces carbon buildup
stabilizes combustion
improves airflow through the engine
reduces internal friction

As a result, workshops consistently observe:

smoother engine operation
improved throttle response
easier acceleration
more stable idle

At the same time, cleaner combustion leads to measurable improvements in exhaust emissions, including:

lower CO (carbon monoxide)
lower HC (unburned hydrocarbons)
lower NOx (nitrogen oxides)
reduced PM / soot particles (PM2.5, PM10)
visibly reduced smoke and opacity

This is why H2E is used primarily as regular preventive maintenance, not only as a last-resort solution.

Why Emission-Related Problems Start in the Engine?

Many exhaust system problems do not originate in the exhaust itself.

Carbon deposits in the combustion space lead to:

incomplete combustion
increased soot formation
higher exhaust gas contamination

These particles then contaminate:

turbochargers
EGR valves
lambda and NOx sensors
differential pressure sensors
catalytic converters
DPF filters

By improving combustion quality at the source, H2E engine carbon cleaning helps slow down contamination across the entire exhaust system.

Regular Maintenance First – Problem Solving When Needed

In daily workshop practice, H2E machines are most often used for:

regular preventive treatments
vehicles driven mainly in urban conditions
high-mileage vehicles

When a vehicle already shows symptoms such as:

increased smoke
emission warnings
rough running
early DPF or EGR issues

H2E engine carbon cleaning is usually the first logical step.

If the issue is in an early stage, the treatment may reduce or resolve it.
If not, H2E becomes a powerful support tool for:

chemical exhaust cleaning
mechanical or manual DPF cleaning
flushing procedures

After any repair or cleaning, an H2E treatment:

delivers an additional measurable effect
slows down re-contamination
helps extend the life of repaired or replaced components

Nothing is wasted.

H2E A-Series Carbon Cleaning Machines Lineup

A-Series machines are designed for auto workshops and service centers that want to offer engine carbon cleaning as a regular, premium service.

All A-Series machines share the same H2E core technology, but differ in flexibility and application range:

H2E SE

Standard preventive engine carbon cleaning

SE machine is used primarily for:

H2E SE is ideal for workshops that want to introduce H2E as a routine service, similar to oil and filter changes.

H2E ECO

Adjustable treatments for higher-mileage and urban vehicles

Eco machine allows technicians to:

It is commonly used for:

H2E Ultra (HD)

High-performance workshop machine

Ultra is the most powerful standard workshop configuration. In its base form, Ultra is suitable for:

Ultra enables:

H2E Ultra also comes in HD variant, which is ideal for engines above 16,000 cc up to 32,000 cc.

H2E C-Series – Systems (continuous-duty operation)

C-Series machines are designed for continuous 24/7 operation in demanding environments. They follow a different usage logic than workshop, A-Series machines.

Effects of H2E Decarbonisation

Independent scientific testing confirmed the effectiveness of each one of our decarbonisation machines and our H2E technology as such.

Post-treatment analysis proved each and every engine became more efficient, cost-effective, and more durable; combined, these improvements lead to the dramatic lowering of operational expenses:

Up to 80% reduction in maintenance costs for key components (DPF/FAP, EGR, catalyst, turbo, injectors, etc.)
Fuel consumption decreased by 4 to 15%
Up to 99% restoration of power and performance

Why H2E delivers stronger and repeatable results

The key difference is not the number of electrodes, but the effective electrolysis surface area.

H2E machines provide:

5–10× larger usable electrolysis surface in a compact design
lower load per surface unit
stable hydrogen and oxygen production
consistent gas quality

A larger effective surface means:

gentler electrolysis
better gas stability
no performance drop over time

This is why:

the first vehicle and the tenth vehicle receive the same effect
results remain stable after months and years of use
H2E outperforms non-regulated and copy machines

Why H2E machines?

H2E is a brand that does not just sell devices – but a complete solution! Each machine comes with support, training, warranty, and supreme technology – result of many years of experience and development.

In addition to not using chemicals and not requiring engine disassembly, H2E devices can be used in almost any service, even in mobile units.
