DiePer & Upgrade – Joint Final Event – 25 September 2019

The DiePer & Upgrade Joint Final Event is a conference on nano particulates (particles > 10nm), diesel and gasoline efficiency improvements and thermodynamic improvements, as well as optimized engine concepts.

The DiePer and Upgrade Final Event took place on Wednesday 25 September at Messecongress, Graz, Austria.
In the morning everyone was welcomed by Virtual Vehicle and AVL List GmbH and throughout the day different partners presented their findings and demonstrated their prototypes.

The one day event was a conference on nano particulates (particles > 10nm), diesel and gasoline efficiency improvements and thermodynamic improvements, as well as optimized engine concepts. . 

The presentations that were held during this event, can be found below.

Towards higher thermodynamic efficiency potential of variable compression ratio for diesel engines – Florence Duffour
A) What results are you the proudest of? The innovative and complete methodology that has been developed, through the panel of tools: 0D, 3D CFD, experimental assessment.
B) Describe the poster in one sentence. Diesel VCR technology: from theoretical approach to real life vehicle use.
C) What is going to happen with the results? The proposed methodology can be integrated into most of combustion system developments.










Exhaust aftertreatment component development; novel approaches to sub 23nm particle filtration – Jeremy Gidney
A) What results are you the proudest of? I am most proud of the low PN emissions we have achieved with the SCRF catalyst without compromising backpressure. 
B) Describe the poster in one sentence. The poster compares the difference in backpressure and PN for conventional catalysed soot filters and those achieved for SCR on filter, demonstrates that the SCRF is both more stable and gives low PN down to 10nm, even at the cold start.
C) What is going to happen with the results? The results are of value when comparing aftertreatment options and we will use them to showcase our low emissions capabilities.









Concept for Lowest PN and High Efficiency – Ludwig Buergler/Philippe Mallet
A) What results are you the proudest of? When we started to work with the vehicle, we could immediately achieve the emission targets on the projected level significantly below the NOx target of 40 mg/km in RDE and WLTC cycles.
B) Describe the poster in one sentence. The poster describes the development route to next generation diesel engines, which are clean in all emissions components and in all driving situations with low CO2.
C) What is going to happen with the results? The advanced energy management strategies are a big step forward in pollutant emission reduction and will be applied to the next generation of diesel drive trains.










Highly Efficient and Clean Light Commercial Vehicle Demonstrator: IVECO Daily – Andy Ward
A) What results are you the proudest of? Achievement of the project targets for efficiency and >10nm particulate number in the IVECO daily vehicle demonstrator.
B) Describe the poster in one sentence. Development of a High Efficiency Light Commercial Vehicle. 
C) What is going to happen with the results? The advanced energy management strategies are a big step forward in pollutant emission reduction and will be applied to the next generation of diesel drive trains.












Robustness over lifetime – Michael Pfragner
A) What results are you the proudest of? Characterizations of catalysts which were poisoned on AVL hotgas testbed in a newly developed procedure, show that the ageing method has a high potential.
B) Describe the poster in one sentence. Evaluation of CO2 and pollutant emissions deterioration in a simulation, where measurement results from AVL hotgas testbench, AVL component testbed and Bosch FIE testrig were used as model input.
C) What is going to happen with the results? Further investigations planned concerning ageing of aftertreatment systems.











Diesel powertrain system modelling – Alexandre Reine
A) What results are you the proudest of? Focusing on soot emissions, engine warm-up and transient operation as well as on (virtual) evaluation of vehicles on driving cycle, the partners have developed, evaluated and validated new models and methodologies using project data.
B) Describe the poster in one sentence. The development of a set of innovative modelling approaches to assess engine, powertrain and vehicle attributes including emissions, by simulation.
C) What is going to happen with the results? The four partners involved in modeling and simulation tasks have developed a set of innovative modeling approaches to serve the project and the industry with enhanced capabilities to assess engine, powertrain and vehicle attributes including emissions, by simulation.










Independent Assessment of Demonstrators – Christian Doppler
A) What results are you the proudest of? I am most proud of showing a very comprehensive picture of emissions for the demonstrators in legal cycles as well as RDE drives for fuel consumption and regulated emissions.
B) Describe the poster in one sentence. The poster explains the methodology of the final assessment as well as the fulfilment/failing of specific targets for each of the two demonstrators.
C) What is going to happen with the results? The results serve mainly as feedback for the two vertical work packages, as achieved and failed targets are illustrated thoroughly.












Life Cycle Assessment of Diesel passenger car & LCV – Helen Jund
A) What results are you the proudest of? Performing the Life Cycle Assessment (LCA) of the vehicles enabled to highlight the role of NOx emissions (driving phase) for several environmental impact categories: secondary PM formation, eutrophication (vegetation overgrowth) or smog formation. Hence the great benefits of their reduction, along with the other emissions reductions, is confirmed. Furthermore, analysing the overall life cycle of the vehicles enabled to point out the main contribution of their production phase to fine PM formation; noticeably, braking PM emissions contribute ahead to tailpipe emissions.
B) Describe the poster in one sentence. Environmental life cycle assessment of ICE vehicles propelled with diesel fuel.
C) What is going to happen with the results? The results of the LCA analysis have shown that improvements on thermal engines can show encouraging environmental impacts reductions under certain circumstances and could contribute to lower GHG emissions of the transportation sector.
