Clogged engine issues

Engine clogging is a real problem!
It increases consumption, reduces performance, releases fumes, causes lags in acceleration and faulty starts and makes the engine management and particulate filter light turn on unexpectedly.

These issues are often caused by a combustion problem, resulting in engine choking.

Engine cleaning with hydrogen

before/after descaling
An alternative solution before replacing clogged parts

Preventive descaling will allow you to regenerate and unclog the parts first to avoid changing them and save on the replacement of turbochargers (from €1,100 to €2,500), catalytic converters (from €500 to €1,600), DPFs (from €500 to €1,600), or EGR valves (from €300 to €400) which are very expensive operations.

The cleaning power of Motor Clean stations is remarkable. Thanks to several years of development and cutting-edge technology, pulsed hydrogen in the intake ducts burns and removes an average of up to 75% of existing dark oxidation deposits (soot) that prevent your engine from running properly.
Our Motor Clean cleaning station produces 3 liters of hydrogen per minute with a purity level of about 97% for a total of 90 liters per 30-minute cycle, allowing a significant increase in calorific value during the treatment phase

Motor Clean station in action


Although it is found in abundance in the universe, hydrogen is a gas that is usually combined with other atoms: it is found in water, oil or natural gases, for example. Hydrogen is considered an energy carrier. It is used mainly in chemistry, refining and industry. But given the environment, hydrogen could eventually play a leading role in the future of energy production. Hydrogen has a very high mass energy density, which means that it contains a lot of energy in a small mass.
hydrogen reaction / Particle filter

It is important to note that today’s cars are equipped with antipollution systems to reduce emissions of CO, CO2, NOx, HC, O2, etc.

These measurements are usually displayed in PPMs for hydrocarbons and as a percentage for carbon monoxide, carbon dioxide and oxygen.

To limit pollution, cars are now equipped with EGR valves. The EGR (Exhaust Gas Recirculation) valve was invented in the United States to reduce NOx emissions by redirecting some of the exhaust gases into the intake circuit to burn it for a second time;

The particulate filter

Particle filter

The particulate filter is part of the exhaust line but it is only present in diesel engines.

Placed after the catalytic converter, it eliminates other fine particulates composed mostly of carbon. Since February 1, 2011 it has been compulsory in new diesel vehicles.

It should be noted, however, that particulate filters can only operate at high temperatures, i.e. during long trips at high speed, and not during daily trips in the city. This post-treatment device is installed on the exhaust system to treat the exhaust gases, thus reducing their harmfulness. Catalytic effect by transforming certain gases into other less polluting components.

To ensure particulate filter efficacy, the temperature of gases must be around 500°C in order to allow spontaneous oxidation of the molecules.

The catalytic converter

the catalytic converter

The catalytic converter is also part of your exhaust system and is useful for gasoline engines and for diesel engines in the fight against polluting emissions.

For a vehicle that runs on gasoline, a catalytic converter referred to as a “3-way” catalytic converter is used that turns nitrogen dioxide and carbon monoxide into a less polluting or non-polluting substance.

For a vehicle with a diesel engine, a 2-way catalytic converter is used to convert unburned hydrocarbons and carbon monoxide in order to release harmless water, nitrogen and carbon dioxide.

It has a “honeycomb” structure consisting of a ceramic monolith made of precious metals such as palladium and uses incoming exhaust gas and engine heat to produce chemicals.

Hydrogen cleaning

Hydrogen is characterized by high reactivity and a burning rate up to five times higher than that of fuels. In addition, hydrogen’s flammability range is larger than that of other fuels. Thanks to these characteristics, adding a small quantity of hydrogen to the fuel-air mixture makes it possible to increase burning rates and make combustion more stable by reducing burning time and decreasing cycle-to-cycle variations.
Various numerical and experimental studies on the impact of the addition of hydrogen in internal combustion engines using gasoline or diesel as a basic fuel have concluded that hydrogen has the following effects:

    - Reduces burning time
    - Increases thermal efficiency
   - Detaches, burns, disintegrates and eliminates soot.
Lastly, for optimum results, we recommend that you drive the vehicle for about 25/30 minutes using a lower gear to keep the engine above 3,000 rpm and remove the last remaining residues from the exhaust.

For prevention, clean your vehicle every 15,000 km or once a year.
