Carbon Cleaning, or the cleaning of Internal Combustion (IC) engines with hydrogen and oxygen (hydroxy) gas - is a technology of the modern age, so it is completely understandable that there are different issues and answers can not be found in connection with it. We will try to find a professionally and scientifically substantiated way to answer all the doubts and concerns about the process of Carbon Cleaning the ICE and the benefits it brings. We warn that the H2E® system is a protected technology for the production of H2E® (hydroxy) gas of reproducible quality, which is produced by: patented production process, specifically engineered electrolyzer cells for this purpose and protected industrial design, specially designed control and power supply, communication of the machine with the server, via the Android application
