Co-Simulation Platform Connecting Chemistry
and Powertrain Dynamics to Traffic Simulation
The differences between greenhouse gas and exhaust emissions from passenger vehicles under laboratory and real conditions have caused the European Commission to introduce more stringent regulations for the vehicle approval procedures. To meet these stringent regulations, the use of novel numerical methods employing virtual calibration, optimisation and prototyping becomes increasingly common.
The overall goal of the project is the development of innovative software for real time simulation of vehicles under real driving conditions to accurately predict fuel consumption and exhaust emissions. A multi-stage modelling is applied that incorporates detailed tabulated chemistry for the description of the combustion and emissions formation processes inside the engine cylinder, aftertreatment system modelling at the microscopic level and the modelling of powertrain, driver and traffic conditions at the macroscopic level. These sub-models will be coupled into a real-time software that will be implemented on a hardware-in-the-loop (HiL) platform to carry out a realistic and inexpensive vehicle virtual calibration and optimisation for RDE applications. The simulation platform will be applicable to vehicles with conventional combustion engines as well with variety of hybrid concepts and hence, be innovative approach for the current market.

Ziel: verbesserte Modellierung der Flammenausbreitung beschäftigen.
Die Flammengeschwindigkeit ist ein wichtiger Parameter für den Verlauf von Verbrennungsprozessen, insbesondere in Benzinmotoren. Gerade für Bedingungen, die typischerweise in Motoren herrschen, ist die Unsicherheit über die Flammengeschwindigkeit noch groß. Daraus folgt, dass bessere Modelle für die Flammengeschwindigkeit direkt das Verbrennungsmodell verbessern. Damit wird eine genauere Vorhersage über (Motor-)Effizienz und Schadstoffbildung möglich.

PaREGEn addresses the short term scope of the GV-02 call via research into and the innovation of gasoline engines for light duty vehicles. Specifically, engines used in mid to premium passenger cars will be addressed. With the electrification smaller vehicles, focusing on larger cars is especially important: the need for clean, efficient & economic engines for inter-urban transport is more urgent and effective to resolve the challenges of air quality, decarbonisation & cost-effective mobility.
Through using state of the art techniques, like optical engines, modelling & simulation tools (for new control strategies or understanding particle formation) and applying new engine componentry, the optimal trade-off between efficiency & emissions will be found. Of attention will be the control of particle numbers between 10 to 23nm. This learning will be used in two, manufacturer lead vehicle demonstrations. These demonstrators will use downsized engines not yet on the market. The two approaches will use different combustion, dilution, fuel injection, boosting and after treatment systems. Completion of the project will show the way forward to a 15% CO2 reduction along with real driving emissions limits. If adopted across all light vehicles these short term engine innovations will reduce the EU vehicle parc emissions by ~2MtCO2 in 2025, 10nm in 2030. As well as improving EU competitiveness, a valuable contribution from PaREGEn will be new tools: to benefit engine design, development & control in general, long after project completion.

Production of second-generation bio-fuel and its influence on engine combustion and emissions (BioEng). This project aims to improve the production processes for 2nd generation biofuels. Using ‘high gravity’ techniques which have higher raw material concentrations, the project will improve the economic feasibility of this promising technology.
Experimental and Computational Tools for Combustion Optimization in Marine and Automotive Engines
The research objectives of the ECCO-MATE project are to develop a synergistic framework for cutting edge research on novel engine technologies for optimizing energy efficiency and minimizing NOx, SOx, and soot emissions, based on state-of-the-art simulation and diagnostic tools for both automotive and marine engines. The research methodology will be based on science in the fields of aerodynamics, two-phase flow and combustion chemistry. The required range of expertise cannot be found in a single institution. Therefore, there is the need for establishing a multi-disciplinary, inter-sectorial and intra-sectorial network, tackling the problems via the development of appropriate tools.
The ECCO-MATE innovation lies on developing common methods for the experimental and computational investigation of marine and automotive diesel engine combustion by coupling state-of the-art two-phase flow and combustion chemistry with advanced engine diagnostic and CFD tools.

Fuel Flexible Engine Platform.
The utilisation of alternative fuels is made possible by providing a truck engine with new components. Injector adapted for fuels with low viscosity and with high volatility. Different types of ignition systems will be evaluated and demonstrated to handle high-octane fuels. Cylinder head and combustion geometry will be modified to handle two separate injectors. The engine will be able to operate in different combustion modes, which allows optimising the efficiency, emissions and fraction of alternative fuel dependent on load and speed. The high degree of flexibility gives the engine a potential for higher efficiency than is possible using only diesel. The project will also lead to increased fundamental understanding of fuel properties and its effect on combustion, through systematic studies spray, engine tests and improved simulation models.
