Mann+Hummel deploys particulate filter to StreetScooter vehicles

To combat particulates caused from electric vehicles’ (EVs) tire, brake and road abrasion, Mann+Hummel (M+H) has developed a dust filter for five StreetScooter test vehicles used by the Deutsche Post DHL Group in five German city centres. Findings from the trial could be used to provide a basis for broader implementation of the solution.

To combat particulates caused from electric vehicles’ (EVs) tire, brake and road abrasion, Mann+Hummel (M+H) has developed a dust filter for five StreetScooter test vehicles used by the Deutsche Post DHL Group in five German city centres. Findings from the trial could be used to provide a basis for broader implementation of the solution.


StreetScooters equipped with the filter are said to generate no carbon dioxide, nitrogen oxide, noise or particulates under consideration of the overall balance during driving operations.
 
The filter has an active filter system and blowers located behind to direct ambient air to the filters, allowing it to operate at a standstill. It is positioned on the underbody at the height of the rear axle where the highest concentration of particulates is found near to the vehicle. All filters are equipped with sensors to monitor the efficiency online. M+H records the filtration performance, amount of cleaned air, concentration of particulates and the weather data. It is then sent to a cloud and evaluated by filtration experts.
 
Alfred Weber, chief executive officer, at M+H said: "More and more people at our locations ranging from Ludwigsburg to Bangalore and Shanghai are suffering from the consequences of air pollution and who else apart from a filtration expert such as us is going to find a solution?".

Weber added that the legislator should concentrate on prescribing limit values and check for compliance while allowing space for the scientific and industrial representatives and their developers to solve how the limit values can be met.

“The coming together of the biggest logistics provider, the biggest producer of electric commercial vehicles in Germany and the global filtration expert has made driving and delivery operations possible in city centres which is neutral in terms of emissions."

    Oregon Department of Transportation's James Whitty discusses his state's progress with VMT fee-based charging. Back in 2001, the state of Oregon stole a lead on the rest of the US when it decided to address the need to do something about the gas tax and its decreasing ability to fund highway construction and upkeep. Recognising that a dwindling pot of money could only shrink further as vehicles became more fuelefficient, Oregon's Legislative Assembly passed laws which led to the setting up, by the state's g
