How Water Injection Works
We incorporated the expertise from various entrepreneurial activities, especially in the field of water injection (e.g. fuel-water emulsion), into Go2water GmbH, which was founded at the beginning of 2020. Its business purpose is the development and marketing of a water injection system (intake manifold) for retrofitting internal combustion engines; the focus is on reducing nitrogen oxide emissions from diesel engines without sacrificing performance, consumption and CO2 emissions. A technology that can be retrofitted to virtually all diesel engines in passenger cars, light commercial vehicles, inland waterway vessels and stationary engines. Water injection lowers the very high combustion temperatures and thus combats the cause of the problematic NOx emissions. The effectiveness of our process has been scientifically proven. The greatest advantage over the systems available to date is the universally applicable, extremely space-saving design, the simple technical controllability, the high availability and the favorable price. Go2water combines a basically proven process with modern know-how and intelligent electronics. Its beneficiaries are both people and the environment.
One hundred percent shareholder of Go2water is Vogtmann und Herold Beteiligungs GmbH, a company of the Vogtmann Group, whose mobility competence is bundled in Vogtmann-Herold+Co.GmbH. The companies are headquartered in Neuwied. Go2water thus benefits from being embedded in an innovative and economically well-positioned traditional company with almost 75 years of diesel expertise.
Retrofitting of Diesel Automobiles
With water injection, distilled water is injected into the engine's intake air as a dispersed spray, depending on the load. This addresses the core problem of the diesel engine: The very high combustion temperatures, the cause of NOx emissions. Go2water reduces the temperature peaks. To a level that continues to ensure the function of diesel particulate filters or storage or oxidation catalytic converters - and starts where exhaust gas recirculation reaches its limits. Go2water water injection can be retrofitted to all passenger car diesel engines in emission classes Euro 4, Euro 5 and Euro 6 b/c without exception. As proven by various research projects, the efficiency of the diesel engines is fully maintained: Fuel consumption and CO2 emissions will not increase, running culture and performance remain unchanged. In the automotive sector, Go2water water injection has a unique selling point: it is currently the only technology available that combats exhaust gas pollutants at source instead of aftertreating them in the exhaust tract. We are working to make the system available for the first engine families under the German Government's Retrofit Directive by the end of 2021. Our core objectives are a favorable price (from 1200 euros including installation for a four-cylinder engine) and the broadest possible model availability. An Initial Assessment by the German Federal Motor Transport Authority (KBA) was completed positively this spring.
Water Injection for Waterways Transport
The high nitrogen oxide pollution in the cities has also led to a focus on the reduction of exhaust emissions from ship engines. Go2water offers river transport a new and very economical way of reducing nitrogen oxide emissions. Water injection makes sense even for the predominantly smaller engines used in passenger shipping. Particularly because the system requires extremely small installation space as well as very little maintenance and does not increase operating costs. Additional benefit for Ship Operators: With the Onboard Electronic Control System, Go2water has not only a NOx sensor but also an integrated fuel consumption sensor. The combination of water injection with new fuels offers further potential for Inland Navigation. A research project using GTL fuel is currently being carried out at HTW Saar University in cooperation with G02water. The aim is to simultaneously reduce nitrogen oxides and fine particles by 50 percent and to completely avoid diesel odours. Water injection can also be combined with diesel particulate filters (DPFs), a measure that will be subsidized by the German Government by up to 90% from the second half of 2021.
*GTL stands for Gas-To-Liquid, a diesel fuel produced from natural gas
THE TEAM BEHIND GO2Water
Experience meets innovation: We share a strong passion for mobility and a dedication to sustainable technologies for a clean environment. In the case of Go2water, this has turned into a commitment to reducing exhaust emissions from existing vehicles, especially since there is huge potential here for keeping the air clean. Technologies such as water injection point to the future, as does their combination with new, alternative fuels. Every drive solution has a raison d'être. Until e-mobility or fuel cells have matured into a real alternative in terms of technology and infrastructure, the internal combustion engine has its justification, especially in combination with green fuels. We need to be open to new technologies; bans make neither social nor economic sense - and ultimately do not improve our carbon footprint.
