FAQ

H2E engine treatment (decarbonisation), is a process of injecting a certain amount of H2E gas into the engine’s air intake. During the treatment, the engine is operating at its default mode, with the aim of inducing the atmosphere in the compression space (and the exhaust system), where the carbon deposits get decomposed.

The term decarbonisation originated in the English language, and stands for the negation of the carbonisation process that takes place within the engine (and the exhaust system) while the car is running. Another term, used interchangeably with decarbonisation is carbon cleaning.

Initially, all the important parameters are entered into the control panel (android application you download to your device). Then, our proprietary algorithm calculates the most optimal operating mode for the best cleaning effects, based on the experience of the previous vehicles we’ve already treated. Then, we turn on the car’s engine and start our machine, which produces gas of certain quality (suitable for your car), which then mixes with the air in the intake manifold, passes through the cylinder and the exhaust system, where it participates in combustion. 

Along the way, the hydrogen binds to the carbon by means of high temperature, thus dissolving hardcore carbon deposits of the course of some twenty thousand combustions (the duration of an average decarbonisation treatment).

The safety and the effectiveness of the H2E decarbonisation has been confirmed by the relevant institutions and the verdict is clear – occasional H2E gas treatment within the checked parameters (amount of H2E gas, treatment duration, and the appropriate operating mode) cannot possibly harm the engine. 

On the contrary, H2E decarbonisation can only positively affect your IC engine – with regular preventative treatments, engine performance is maintained so that the engine that would otherwise fail, continues to operate without issues. Regular treatment protects the engine from the accumulation of soot, but also has a positive effect on the service life of the engine’s peripherals – DPF, catalytic converter, turbine, EGR, and the intake manifold.

Decarbonisation effects depend on the type and the condition of the engine being treated, as well as the gas and the technology used to carry out the entire treatment. H2E technology will bring about the maximum decarbonisation benefits, regardless of type of engine and fuel (diesel, gasoline, LPG).

The parameters affecting the treatment quality (duration, engine operation mode, gas quality/quantity) are optimized in advance based on the previous owner’s feedback, service stations, and the reference laboratories/institutions for vehicle engine testing.

Thanks to the patented gas production process of repeatable quality, service clients who apply H2E technology have no reason to worry. The only prerequisite is for the operator to follow the instructions and ensure the treatment process runs smoothly.

H2E Decarbonization can be done on all types of engines, regardless of the type of fuel, though the effects depend on the type and the condition of the given vehicle. Each treatment will bring the engine closer to its factory condition, thus paying off in driving pleasure and lower fuel consumption. Furthermore, the reliability of the engine increases, general failure and overhaul of expensive engine parts (and engine peripherals) is postponed, so the H2E decarbonisation treatment pays off many times over.

In short, H2E cannot damage fuel injectors; because, unlike chemical additives that mix in with the fuel, H2E gas mixes with air (does not penetrate inside the injectors). 

In engines with direct fuel injection into the cylinder, H2E decomposes deposits on the “head of the nozzles”, which will then have a positive effect and promote proper injection. The nozzles located before the intake valves are not directly affected by H2E gas, as high temperature/pressure is required to bind hydrogen and carbon. 

The H2E positive effect in all types of engines is preventive, because after the treatment, the raw emission of exhaust gases and particles that go through the EGR pollute the intake manifold, and therefore the exhaust, are significantly reduced.

Note: It often happens that service technicians use diagnostics to read improper operation of the nozzle (correction of acceleration according to the cylinders of the allowed parameters), and that the essence of the problem is a dirty “nozzle head” or combustion chamber. In any case, it is preferable to perform the treatment before replacing or repairing the nozzle because:

• There is a chance that the correction will return to normal
• Stubborn carbon deposits that make disassembly difficult, if it is necessary, will be significantly reduced/softened
• New/refurbished nozzles will get less dirty

No, on the contrary, H2E decarbonization will restore lost engine performance and compression. 

As the engine runs, carbon deposits may interfere with proper sealing and prevent the pistons from running against the cylinder walls. By removing these carbon deposits, we allow for a tighter fit, increased sealing, and stronger compressions.Note: H2E decarbonization is intended as a preventive service of the compression space and exhaust manifold. The service that performs the treatment is obliged to determine the condition of the engine before the treatment itself. H2E technology enables more experienced repairmen to repair certain faults on their own responsibility.

No, decarbonization cannot clean the intake manifold. H2E decarbonization has a preventive effect resulting in a significantly slower accumulation of deposits caused by exhaust gas emissions as well as a significant, scientifically proven reduction in raw exhaust emissions.

During the H2E treatment, hydrogen binds with hard carbon deposits exclusively through the high temperature that is a consequence of normal engine operation. This means that the direct decomposition of deposits starts from the seat of the intake valve (after the intake manifold).

Most of the H2E (hydrogen and oxygen) gas burns at the very beginning of regular ignition, reduces air and fuel, turns into superheated water vapor and we get the effect of “steam cleaning” of the cylinder and exhaust system. A smaller part of superheated water vapor and H2E gas with exhaust gases, depending on the engine operating mode during the treatment, comes into contact with the EGR valve and has a positive effect on it. It often happens in practice that after the H2E treatment, an error indicating a malfunction of the EGR valve is turned off, but it cannot be said that it has been cleaned, only removed. 

In any case, only one H2E treatment significantly delays the moment when mechanical cleaning of the EGR valve and intake manifold will be required. If the time for mechanical cleaning has already come, H2E treatment immediately before or after mechanical cleaning will significantly prolong the following. When H2E treatment is applied regularly there is a high probability that problems with the intake manifold and EGR will never occur.

After H2E decarbonization, it is not necessary to perform a minor service (filter and oil replacement).

The direct influence of H2E decarbonization is possible only through the exhaust gases that penetrate into the crankcase and mix with the crankcase gases.

The indirect impact of H2E decarbonization is far more important because tests by relevant institutions have confirmed that the raw emission of harmful exhaust gases (combustion by-products before the catalyst and particle filter) is significantly reduced., meaning that fewer harmful gases and particles penetrate into the crankcase and mix with crankcase gases and engine oil. This also explains better condition of the engine oil during the service interval in vehicles where H2E decarbonization was applied.

By regularly treating the engine with H2E gas, we reduce the accumulation of oil deposits in the crankcase and oil lines, because it is precisely the increased emission of exhaust gases, that is, poor fuel combustion, that causes it. Poor fuel combustion increases the amount of harmful particles that remain on the cylinder rods, the oil rings (oil links) pull them into the engine crankcase during piston movement, and the oil pump distributes them throughout the entire oil system.

According to our customers’ experiences, yes, but the actual percentage will vary because each customer is different and has different driving preferences.

The general feedback after decarbonization, which is reflected in the first place in the significant reduction of harmful exhaust gases (CO, HC, NOx…), clearly indicates a return of efficiency closer to the factory parameters. Most H2E treatment clients surveyed reported consumption reductions of 8% or more, but the precise measurement of consumption is highly debatable due to the variations in driving styles.

You can repeat the treatment whenever you think it is necessary, because the decarbonization process does not harm the engine. Bearing in mind that this procedure removes soot from the car’s engine (which will certainly accumulate again over time) – the decision on the interval of repeating this procedure is left solely to the owner of the vehicle.

Depending on the mileage traveled, as well as the amount of accumulated soot, the procedure can be repeated shortly after the first time, in order to achieve the highest benefits. On the other hand, the procedure can be done once and never again.

However, as we have seen for ourselves the results of H2E procedure – repetition is necessary at a certain interval, depending on the type of engine. That interval is about 10,000 km for diesel engines, about 20,000 km for gasoline engines, while about 30,000 km for engines that use LPG or CNG for propulsion.

Depending on how much soot deposits were in the engine, some clients decided to do a second treatment shortly after the first and then noticed a significant difference in the performance of the car. On the other hand, you can plan decarbonization (for example) once a year and thus continuously get rid of deposits from the engine.

Not only that it can, it’s especially recommended for these types of engines. Taking into account that vehicles with high-pressure mechanical pumps are quite old and have traveled many kilometers, it is highly recommended to do a treatment to refresh the engine – refreshing the engine in the sense of getting rid of deposits that have accumulated over the years on the exhaust manifold, valve seats and other parts of the engine.

No, the by-product of hydrogen and carbon bonding is in a gaseous state and as such is not retained in the catalyst and particulate filter. Due to the high temperature, which occurs while the engine is running, part of the hydrogen from the H2E gas binds with carbon and turns it into a hydrocarbon. Hydrocarbon is also a gas that cannot be contained in the catalytic converter and particulate filter.

As a byproduct after the combustion of the mixture of air, fuel and H2E® gas, superheated water vapor comes out, the amount of which increases significantly during decarbonization, which increases the humidity of the exhaust gases, which leads to the dissolution of soot, soot and carbon deposits in the exhaust block, exhaust manifold and peripherals such as the EGR valve, catalyst, DP filter and other parts of the exhaust system, such as differential pressure sensors and lambda probes.

The answer is absolutely NO. The engine components themselves contain moisture from the surrounding air on their surface, which, during sudden heating (such as engine start-up and operation), turns into condensate. Namely, there is a big temperature difference between the working elements of the engine and the surrounding air itself, which creates condensate, which evaporates after the engine is fully heated.

This phenomenon is especially noticeable when the engine is started in winter, so we can safely say that engine decarbonization cannot lead to engine corrosion, because the parts and components themselves are designed and manufactured so that they do not corrode. Moisture itself can appear at any time in certain parts of the engine, and even in the fuel, without affecting in any way the performance of the vehicle and/or the corrosion of certain engine components.

With H2E decarbonization, this danger does not exist. Namely, the intercooler is not in contact with the exhaust gases, nor the compressor section of the turbine. 

Directly – by binding H2E gas with carbon deposits, and indirectly by the fact that after treatment, the emission of particles that pollute the turbine significantly decreases, H2E gas exclusively begins to react – to bind particles of soot and carbon at high temperatures. 

Therefore, there is no return of hydrogen to the intake manifold of the engine.

After the decarbonization process itself, it is necessary to take the car out on the open road and drive 10-12 km to expel the dissolved elements of soot and carbon deposits from the entire exhaust system, turbine, EGR valve, including the exhaust manifold, catalyst, middle and rear boiler, as well as the DPF/FAP filter in newer diesel units.

It is recommended to drive those 10-12 km in one working cycle, so that the engine reaches operating temperature and achieves optimal sealing and efficient combustion. As a result, the compression part of the engine and the exhaust block become significantly cleaner after treatment and driving.

Engine cleaning with H2E gas is definitely the most effective and safest cleaning method. The answer to the question of why we waited so long for this technology to become widely accessible lies in the very nature of water electrolysis. Namely, electrolysis is a rather unstable process, and the electrolyzer itself, a rather complicated instrument.

Also, the product of classical electrolysis is very unstable and changeable, as are the conditions in which the device is used. In addition, it is sensitive to: voltage and temperature changes, atmospheric influences, such as air pressure, air humidity and the altitude where the machine is located.

Hybrid Power System engineers have developed an electrolyzer, power supply and management (complete system), which largely eliminates all external influences such as temperature, pressure and air humidity, as well as the altitude at which the machine is located.

In this way, we obtained hydrogen and oxygen gas of reproducible quality, and named it H2E®. Based on this technology, it is now possible to expect the same quality of decarbonization, regardless of atmospheric influences, the state of the city’s electrical network and the current state of the electrolyzer.

What we offer is H2E® gas of repeatable quality, which in practice means that the quality of the gas is the same in all atmospheric conditions, regardless of external parameters such as temperature, pressure, air humidity or altitude at which the treatment is performed.

Thanks to this – the H2E machine produces gas of the same quality, which we then adjust to each vehicle, based on our proprietary algorithm. It is also the first IoT machine of its kind in the world, which generates a database with feedback from users. Our working principle is “turnkey”, and our motto is uncompromising quality in everything we do.
