The burning of hydrocarbon fuels such as gasoline, diesel, liquefied propane-butane, or methane in the engine releases carbon deposits. With the mileage, the carbon residue becomes larger, accumulating over important parts and interfering with the regular operation of the engine. As a result, the engine loses it's original dynamic parameters!
When hydrogen (H) added to the regular fuel-air mixture of the engine with the help of the temperature in the cylinders, it reacts with carbon (C), and it's converted to methane (CH2,4,6,8 ...), burns and leaves through the exhaust system. The process of transformation of carbon deposits absorbs temperature, which is necessary for the chemical reaction but does not create additional heat!
It takes between 20 and 60 minutes to add a specific flow of hydrogen gas to the engine running to get the decarbonization done! Carbon Cleaner machines, which are designed, manufactured, and certified in Europe have 12V, 220V, and 380V and custom models with different flow rates of HHO. The solution to prevent carbon build-up is to do the engine carbon cleaning procedure once a year or every 15 thousand kilometers.
