HBPO showcases joint project with MANN + HUMMEL at the IAA

The Lippstadt-based automotive supplier HBPO is exhibiting at the IAA this year once again, and presenting a world first, jointly developed with partner MANN + HUMMEL. The two companies have designed a particulate filter that can be integrated directly in the front-end module. This ensures that vehicles with combustion engines have a particulate emission level comparable with electric vehicles.

There have never been filters for direct integration in the vehicle front-end available before. The particulate matter produced by other road users is trapped directly by a filter.

The filter was developed by MANN + HUMMEL – long-standing partner supplier of HBPO – in collaboration with the global market leader from Lippstadt. HBPO was then responsible for integration in the front-end module. “There is not a great deal of space in the vehicle front-end – we have to make clever use of the design space,” explains Guido Opperbeck, Manager Research & Development at HBPO. The flexible filter elements from MANN+HUMMEL are integrated between the radiator and bumper. An active air control system between these regulates the thermal management and optimises the CD value by intelligent opening and closing of the air flaps.

Ultimately, the particulate matter balance of every vehicle thus equipped can be improved. With the new development, vehicles with combustion engines could achieve the particulate matter balance of a purely electric powered vehicle.

This is made possible by a powerful filter element that would have to be replaced regularly – during the annual inspection, for example. The replaceable element developed especially for this can be removed and replaced easily.


Commitment to better air quality

The particulate filter integrated in the front-end module has been designed for active and passive use. In passive mode, the system filters the air flowing through during travel and thus reduces the concentration of particulate matter. In active mode, the fan located behind the radiator increases the volume of air flowing through the filter and thus the filtration capacity. The aim is to achieve a vehicle emission balance even in passive mode on a par with the level of a purely electric vehicle in cities where the WHO limit of 50 micrograms per cubic metre is exceeded.


Intelligent systems could also use sensors to control the filter system in such a way that filtration capacity is regulated depending on ambient conditions and the related concentration of particulate matter. This way, optimum filtration capacity can be ensured in all situations, thus improving the particulate emission balance of the vehicle.

This world first is a solution for all vehicle categories, no matter which type of drive they have. It thus contributes to cleaner air and cleaner mobility in new vehicles.
