Exhaust aftertreatment systems for public transport buses

Cities and towns in particular should serve as role models in respect of ecological and health concerns. And buses are a central pillar of the public transport system. Consequently, the task of cutting pollutant emissions has an important role to play in urban public transport, because the public view the public transport system as an especially "green" form of transportation. By consistently equipping or retrofitting their buses with state-of-the-art exhaust aftertreatment system, municipal transport authorities can respond to the expectations of their citizens.

Diesel emissions can be almost entirely eliminated by means of enclosed diesel particulate filters made by HJS. Use of an HJS SCRT® (Selective Catalytic Reduction Technology) system enables not only particulate but also NOx emissions to be effectively and efficiently reduced.
