Back to the future.

It happens quite often that the engine for which we develop our filtration solution is still under development itself and is therefore an engine of the future. The intense exchange and constant updating of the development status on both sides, and a collaboration based on trust at partnership level are the prerequisites for successful development work. It is particularly important to us to identify tomorrow’s changes and trends in automotive and engine manufacturing at an early stage, so that we can come up with solution methods in a proactive way. We mainly focus on the following trends:


Engine manufacturers are trying to develop engines with less and less weight and smaller cylinder capacity while at the same time increasing performance. This also reduces fuel consumption and it increases the challenges we face. The main challenge is to create solutions that take up as little space as possible, have a low weight and a minimum of final assembly effort and time. Moreover, they have to cope with the high efficiency of an engine with as little maintenance requirements as possible.

Lightweight construction

Size and weight are not only a matter of design, but also of the material used. The material too, is an additional important focus: the right choice of material has a significant impact on driving power, on the reduction of operating costs and on fuel consumption. And that in turn leads to a reduction in CO2 emissions. In addition, lightweight construction stands for a reduction of raw materials needed and in the end it also reduces waste.

Hybrid construction

We are intensely working on the development of aluminum-plastic hybrid components: owing to our know-how in pressure casting and in die casting we have the best conditions to implement the ecological and economic advantage of this type of construction in the best possible way. So finally the end customer can reduce his fuel consumption and CO2 emissions.

Energetic® series

It has nearly become a constant trend at Hengst to develop product solutions generating as little waste as possible. As early as in 1995, we launched our Energetic® series as an environmentally friendly alternative to the spin-on filter.

Our Energetic® series consists of service-friendly cup filter systems with long-lasting housings where only the filter insert has to be changed. The filter insert is free of metal and completely thermally recyclable. Up to 80% of the waste can be avoided by using an Energetic® component.
