Water Injection Systems

The power of water

Water can do amazing things in high performance engines. Like our special water injection technology, for example, which noticeably reduces fuel consumption in gasoline engines. This means not only lower costs, but also lower CO2 emissions. What's more, the cooling effect of water in the combustion chamber enables us to achieve more power and torque - water-based driving pleasure, so to speak.


Using expertise

As experts in SCR tank systems for diesel engines, we know exactly what is important when it comes to tank architecture, interfaces and customer needs. In addition, our solutions master the special challenges of water injection systems. This is how we get liquid handling in dynamic conditions, a higher heating capacity and the formation of biofilm under control.


Development in flow

Our water injection systems are designed as complete solutions that meet all the requirements of a modern additive tank system. Our experts are constantly working on improvements in terms of freezing behaviour, usable liquid volume and minimisation of sloshing noises.

The most important highlights

With us, engineering, toolmaking, equipment and processes for mass production come from one source. Thanks to our dense network of locations, we are almost always in the direct vicinity of our customers all over the world.
