The current Stage IV/Tier4f limits for engine emissions of construction machines is enforcing an even more stringent use of after treatment system as seen already during Stage IIIB/Tier4i emission limits introduction. Our Liebherr Machines Bulle proposal is a simple and cost effective approach with no EGR and SCR only (no DOC, no DPF). In addition to this standard Stage4/tier4f solution, this paper will then presented in details our technical solutions and results of a combined SCR on Filter systems currently in development for specific markets needs and preparing any further legislations steps.

The AGCO Power Inc. located in Finland is as one of the most important suppliers for heavy duty diesel engines mainly used for agricultural and industrial applications. To overcome the challenges for Tier4f / Stage 4 emission regulations for their new engines a high sophisticated SCR control strategy was developed in a close cooperation with the engineering partner AVL. To handle the wide range of applications (Tractors, Combines, Forest machines, ..) for the different customers (Challenger, Fendt, Massey Ferguson, Valtra, ..) for 8 main engine types (from 3 up to 12 cylinder engines) using two technology routes (EGR + SCR and SCR only) with a minimum calibration effort, a model based approach was used within the whole development phase. Different SCR technologies were analyzed and their behavior transferred into physical models in the AVL MoBEO development environment. The same model parameters are also used for the real-time models in the ECU (Engine Control Unit), which are one of the core elements for the model based dosing control.

The purpose of this paper is to demonstrate the impact of low- floor bus seating configuration, passenger load factor (PLF) and passenger characteristics on individual boarding and disembarking (B-D) times -a key component of vehicle dwell time and overall transit system performance. A laboratory study was conducted using a static full-scale mock-up of a low-floor bus. Users of wheeled mobility devices (n=48) and walking aids (n=22), and visually impaired (n=17) and able-bodied (n=17) users evaluated three bus layout configurations at two PLF levels yielding information on B-D performance. Statistical regression models of B-D times helped quantify relative contributions of layout, PLF, and user characteristics viz., impairment type, power grip strength, and speed of ambulation or wheelchair propulsion. Wheeled mobility device users, and individuals with lower grip strength and slower speed were impacted greater by vehicle design resulting in increased dwell time. To ensure safe, efficient and equitable access to the diverse spectrum of transit riders, transit system design needs approaches that transcend existing minimum federal accessibility design standards.
