To meet Euro VI emissions requirements has been the central development focus for the current generation of HD diesel engines in the past. Today – after having achieved this challenging target reliable – the development focus changes. Facing significantly increased product cost as well as upcoming legal fuel efficiency respectively CO2 emissions targets, now improved fuel efficiency as well as the reduction of product cost are the main development targets of next generation HD diesel engines. In this presentation AVL will highlight the potentials and challenges of advanced technologies for next generation HD diesel engines, like high advanced air handling, consequent engine downspeeding, advanced aftertreatment systems, waste heat recovery, etc...

Someday, the story of a well-proven engine concept inevitably comes to an end. In the mid-nineties, the 900 series replaced the legendary engines of the 300 class, which formed the backbone of the Mercedes-Benz medium duty powertrain since 1949. Fifteen years later, Daimler Trucks is now presenting the engines OM 934 and OM 936 of the new developed Medium Duty Engine Generation (MDEG) to replace this likewise successful 900 engine class. The presentation illustrates selected highlights of the MDEG’s thermodynamic concept as well as the technology of catalysis and exhaust gas filtration in consideration of the constraints of the EURO VI and the EU-Stage IV/Tier 4 final legislation.

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 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 challenge for non-integrated diesel engine manufacturers such as DEUTZ is the high diversity of industrial applications. To comply with the current EU Stage IV / US Tier 4 final emission standards, meeting customer’s expectations at the same time such as compact design, power density or fuel consumption results in different engine and exhaust aftertreatment configurations. Furthermore, different customer load profiles and engine power ratings require the development of engine operating modes for thermal management. For specific applications the engine calibration needs to be adopted to ensure e.g passive DPF regeneration. The presentation provides an overview of the modular technology concepts enabling optimised installation solutions and emphasises the control of the aftertreatment system for trouble-free machine operation.

On a global scale, racecars burn an irrelevant amount of fuel, so racing series’ interest in fuel-saving technology has nothing to do with saving the planet from racecars’ environmental impact. Transporting teams to the tracks burns far more fossil fuels than any fuel actually consumed at the track.
