The improved efficiencies of the modern diesel engine have led to its increased use within the mobility industry. The vast majority of these diesel engines employ a high-pressure common rail fuel injection system to increase the engine's fuel-saving potential, emissions reduction, and overall performance. This one-day seminar will begin with a review of the basic principles of diesel engines and fuel injection systems. Diesel and alternative fuels will be discussed, followed by current and emerging diesel engine applications. The majority of the day will be dedicated to the common rail system itself, beginning with a comprehensive overview of the complete system. The instructor will then introduce the main subsystems, including hydraulics and controls. Finally, the subsystems will then be broken-down into their respective components.

Mixed mode with auto ignition but inhomogeneous charge. Injection-controlled but with EOI before SOC. Papers describing experiments and test data, simulation results focused on applications, fuel/additive effects, combustion control, and PPC injection strategies are invited and will be placed in appropriate sub-sessions. Papers with an emphasis on the modeling aspects of combustion are encouraged to be submitted into PFL110 or PFL120 modeling sessions.

Mixed modes with both flame propagation and slow auto ignition. Distinct from SI knock: autoignition is desired and will not ruin the engine. Papers describing experiments and test data, simulation results focused on applications, fuel/additive effects, and SACI mode change are invited and will be placed in appropriate sub-sessions. Papers with an emphasis on the modeling aspects of combustion are encouraged to be submitted into PFL 110 or PFL120 modeling sessions.

Engines can and do experience failures in the field in a variety of equipment, vehicles, and applications. On occasion, a single vehicle type or equipment family will even experience multiple engine failures leading to the inevitable need to determine what the most likely cause of one or all of those failures was. This comprehensive seminar introduces participants to the methods and techniques used to determine the most likely cause of an individual engine or group of engine failures in the field. The seminar begins with a review of engine design architecture and operating cycles, integration of the engine into the vehicle itself, and finally customer duty cycles and operating environments. Special emphasis is placed on the number and type of subsystems that not only exist within the engine (diesel and gasoline) but are used to integrate the engine into the overall vehicle package. Following this review, participants learn about failure types, investigation techniques, inspection methods, and how to analyze the available evidence using their own knowledge of engine and vehicle operating characteristics to determine the most likely cause of an engine(s) failure.

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.

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...

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.
