"We are experiencing the evolution of internal combustion engines literally live. It is surprising that it was the Slovaks who deserved it, even though some questions are still unanswered..." RTU Europe, headed by Dick Kvetňanský, is the manufacturer of the innovative RTU eFone combustion engine. In addition to its claimed high fuel efficiency of over 55%, it produces only minimal waste heat and produces power exceeding 800 horsepower. Is this even possible?
When the RTU engine is mentioned in the media, we often come across descriptions such as revolutionary and groundbreaking. However, probably every engine expert will agree that the RTU is more of an innovation and evolution than a revolution. The RTU uses practically the same basis for its operation as a conventional gasoline engine, and can even be assembled from an older diesel engine. It is enriched with new materials and elements that allow it not to produce waste heat on such a massive scale as we encounter in conventional engines. Their ability not to convert liquid fuel into waste heat is one of the most significant innovations that the RTU brings to the world of motoring.
The high efficiency of the RTU engine, hovering around 70 percent, is due to several factors. The most important of these is the aforementioned reduction of waste heat through the use of materials with low friction resistance, a modified combustion process and its own electronically controlled management of the engine's operation. Probably the most interesting innovative element is the use of a completely new piston material. According to its manufacturer, it can literally be wrapped around a finger, but at the same time it can handle 250 times higher pressure than atmospheric pressure. Its production takes place at an extremely high temperature, which changes the material at the molecular level to such an extent that even subsequent spectral analysis cannot detect the original material. Spectral analysis is also used very effectively by many NASA devices worth millions of US dollars. So where is the truth?
Pseudo-adiabatic engine RTU in brief
• does not require cooling or a catalyst
• you can grab it with your hand even during operation
• efficiency 60 to 70%
• power up to 814 horsepower
• significantly lower consumption of around 5.3 liters
• significantly lower exhalations
• possibility of conversion from a classic 4-stroke turbo engine
RTU motors are made from ceramic materials starting from 80%. This is not the ceramic you have in your kitchen, but a complicated and reliable material with excellent technical properties. Part of the development of the RTU motor also required the creation of a completely new way of checking the internal structure of ceramic materials, because they cannot be checked for cracks like metals. RTU Europe has created a method and LWS device that can detect defects in materials during the creation of a specific motor element.
The advantages of ceramic materials can be summarized as follows:
• absence of material failures
• LWS (Light Wave Sensor) measuring device completely eliminates the risk of hidden cracks
• non-metal
• non-conductive (does not conduct heat or electricity)
• low friction and natural gliding capabilities require little or no lubrication
• it is not possible to use the magna-flux technique or X-rays
• low production costs
• production in final form and dimensions
• alternative for a wide range of metal products
Almost adiabatic effect
The name of the technology used by the RTU Europe engine does not mean anything to the uninitiated, and even an expert will pause to consider the meaning of its wording. The adiabatic effect is one in which there is no heat exchange of gas (and therefore air). In the case of the RTU engine, its operation has come very close to an adiabatic phenomenon, which is why the creator added the word “pseudo”. The engine approaches this effect primarily thanks to the subcooled intake air, down to -20 °C. RTU Europe claims that their engine does not need cooling. Several unanswered questions arise about the RTU pseudo-adiabatic engine, which primarily concern its energy consumption. However, the truth is that this engine, created from an in-line 5-cylinder 2.5-liter engine from the Audi TT RS, has already been tested in real life and successfully, and even on the brake (2 days of continuous operation with the brake active).
The future of RTU is not just about the pseudo-adiabatic engine
RTU was not satisfied with the results achieved in the practical application of pseudo-adiabatic processes in combustion engines. Therefore, they are already preparing the Electroliner project, which combines a compact miniaturized diesel engine using RTU technology, an efficient capacitor and a highly efficient electric motor, resulting in a power unit designed for bus, ship, rail or truck transport. In reality, it should be a hybrid power unit, the development of which is currently being carried out by many car manufacturers either independently or as part of their joint venture projects.
Despite the fact that the innovative RTU engine made headlines in all kinds of media late last year, its creator has persistently ignored the publication of any technical details. Today, we can only believe that Dick Kvetňanský is not exaggerating and that the world has truly witnessed a significant engine innovation with Slovak capital.
Slovak capital is responsible for innovations in engines
"We experience an evolution of combustion engines verbatim in live broadcast. Surprising is that just Slovaks deserved it, even if some questions are still not answered..." Erik Stríž
Company RTU Europe, whose head is Dick Kvetňanský, is the producer of an innovative combustion engine RTU eFone. It besides the alleged high efficiency of fuel consumption, more than 55%, produces only minimal waste heat and produces the performance exceeding 800 horsepower. Is it ever possible?
If there is a mention of the engine RTU in the media, we often meet with the labels as revolutionary and epoch-making. Probably every expert in engines will agree on the fact that RTU is more an innovation and evolution than revolution. RTU uses for its activity practically the same basis as the usual petrol aggregate, it can even be put together also from an older diesel engine. It is enriched by new materials and components which enable it not to produce waste heat to such a massive extent as we see with common engines. Just the ability not to change the liquid fuel into waste heat is one of the most meaningful innovations which brings RTU to the world of motoring.
High effectiveness of RTU engine, balancing for about the level up to 70%, is conditioned by more factors. An important thing is just the mentioned waste heat reduction with the help of using low rub resistance materials, modified combustion process and own electronically controlled engine activity management. Probably the most interesting innovative component is the use of totally new piston material. According to the words of its producer, it can be verbatim wind round the finger, however, at the same time it handles 250 times higher pressure than the atmospheric. It is made by extreme high temperature which changes the material on the molecular level at such a rate, that even by the following spectral analysis it is not possible to reveal an original material. Many devices of NASA are exploiting very effectively the spectral analysis in the value of millions of American dollars. Where is the truth then?
Pseudo-adiabatic engine RTU foreshorten
• no cooling and converter needed
• you can touch it by hand also during an activity
• effectiveness of 60% to 70%
• performance to 814 horsepower
• markedly lower consumption around 5.3 liters
• markedly lower air pollutants
• possibility of rebuilding from a classic 4-stroke turboengine
RTU engines are more than 80% made from ceramic materials. It is not the ceramic that you have in the kitchen, but it is complicated and reliable material with excellent technical qualities. A part of RTU engine development also required creating a totally new way of inside structure control of ceramic materials because it is not possible to control the origin of cracks by them as by metals. RTU Europe created a method and device LWS which can releave the material imperfections already during the making of concrete engine components.
We can summarize the advantages of ceramic materials also as follows:
• no material failures
• measuring device LWS (Light Wave Sensor) completely reduces the risk of hidden cracks
• non-metallic
• non-conductor (it does not transfer heat or electric current)
• low friction level and natural sliding abilities require only little or no lubrication
• it is not possible to use magna-flux or X-ray technology
• low production costs
• production in final form and dimensions
• alternative for a wide range of metal products
Almost an adiabatic effect
Name of technology which is used by engine from RTU Europe says nothing to disinterested and even an expert demurs to meaning of its wording. An adiabatic effect means the effect where there is no heat exchange of gas (as well as air). In the case of RTU engine, its activity very approached the adiabatic phenomenon, therefore the creator added the word "pseudo". An engine approaches this effect especially thanks to overcooled sucked air to -20 °C. However, RTU Europe claims that its engine does not need cooling. There are several unanswered questions about presudo-adiabatic RTU engine. They concern especially the energy consumption. However, the truth is that this engine made from serial 5-cylinder 2.5-liter engine from Audi TT RS was already for real and successfully tested and even also on brake (2 days of continuous run with an
active brake).
The future of RTU is not only about a pseudo-adiabatic engine
In RTU they were not satisfied either with achieved results by practical application of pseudo-adiabatic processes in combustion engines. Therefore they are already today preparing the project Electroliner where there is a connection of compact miniaturized diesel engine using the RTU technology, an effective condenser and high effective electroengine and the result is a driving aggregate designed for bus, ship, rail or truck transportation. In fact, it concerns a hybrid driving unit in the development of which many carmakers are participating today either independently or within their joint-venture projects.
Even though the innovative RTU engine got on the prominent places in media of every kind at the end of last year, its creator is persistently ignoring the publishing of any technical details. Today we can therefore only believe that Dick Kvetňanský is really not exaggerating and the world is waiting to see a really significant innovation of engines with the Slovak capital.
