Papers are invited on technology developments and the integration of these technologies into new emission control systems. Topics include the integration of various diesel particulate matter (PM) and diesel Nitrogen Oxide (NOx) reduction technologies plus analogous technologies for the growing population of direct injection gasoline engines. Novel developments in sensors and control systems will also be considered.

Papers are invited for this session on particle emissions from combustion engines, including measurement and testing methods, and the effects of changes in fuel composition. Papers are also invited on the topics of the environmental and health effects of elemental carbon and organic carbon that constitutes solid cored particles plus the environmental and health effects of secondary organic aerosol emissions. This includes particulate emissions from both gasoline and diesel engines.

Papers for this session on the general topic of combustion engine gaseous emissions (regulated and non-regulated). This includes hydrocarbon species production over aftertreatment devices as a result of changes in fuel specification and the inclusion of bio-derived components, specific NOx species production over catalytic devices, well-to-wheels CO2 production for alternative technologies and consideration of secondary emissions production (slip) as a result of aftertreatment.

Designing more efficient and robust emission control components and exhaust systems results in more efficient performance, reduced backpressure and fuel penalty, and higher conversion efficiency. This course will help you to understand the motion of exhaust flow in both gasoline and diesel emission control components including flow-through and wall-flow devices such as catalytic converters, NOx adsorbers, diesel oxidation catalysts, diesel particulate filters as well as flow through the overall exhaust system. Discussions will also cover: flow recirculation in inlet cones, flow maldistribution and its effect on conversion efficiency in flow throughs, non-uniform particulate deposit in diesel filters, and roots of non-uniformity in flow distribution due to exhaust system design such as bends.

As diesel emissions regulations have become more and more stringent, diesel particulate filters (DPF) have become possibly the most important and complex diesel aftertreatment device. This seminar covers many DPF-related topics using fundamentals from various branches of applied sciences such as porous media, filtration and materials sciences and will provide the student with both a theoretical as well as an applications-oriented approach to enhance the design and reliability of aftertreatment platforms. Structure, geometry, composition, performance, applications and optimizations of DPFs are some of the main topics covered in this advanced level seminar. Computer simulation techniques for analysis and optimization of DPF performance are also demonstrated.

All gasoline powered vehicles and equipment create exhaust and evaporative and refueling emissions. Unlike exhaust emissions, which occur only when the engine is operating, evaporative emissions (evap emissions) occur all the time. Controlling evap emissions to PZEV levels is as challenging as controlling exhaust emissions. It becomes even more important in the case of plug-in hybrid electric vehicles (PHEV) and extended range electric vehicles (EREV) which generate evaporative fuel vapors, but have no place to burn/consume the vapors when the engine does not operate for extended periods of time. Constantly changing evaporative regulations including new test procedures for accommodating future EREVs and PHEVs vehicle evap systems, new test fuels to reflect changing commercial gasolines, identifying and controlling new sources of fuel vapor emissions, etc., require that individuals working in this area have a solid understanding of both regulatory and system design issues for evap emissions 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 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 environmental and health impact of individual vehicles/vessels are regulated through various legal acts by the European Commission. For energy efficiency or emissions of carbon dioxide, thus the climate impact the situation is different especially if all modes of transport is included. With the Euro VI regulations the shortcomings of previous emission stages, i.e. real driving emissions, seems to have been solved making road transport a clean choice of transport for the first time. The traditional green modes of transport like diesel rail and inland waterway vessels lag behind, both in stringency and real world emissions but are energy efficient.
