CO2 REduction for long distance transport (CORE)

The project proposal CORE (CO2 REduction for long distance transport) is a collaborative large-scale integrating project for a call within FP7-SUSTAINABLE SURFACE TRANSPORT (SST)-2011-RTD-1. The project consortium consists of three truck manufactures in Europe, Volvo, Daimler and IVECO, together with 13 other partners in the automotive industry and universities.The objective is to demonstrate a substantial reduction of CO2 emissions, 15% improved fuel efficiency compared to a EURO V engine and at the same time fulfilling EURO VI emission legislation. By using novel technology and combine them in flexible engines with a high level of precise control, performance advantages will be achieved with improvements in emissions and fuel consumption. The research will focus on efficient air management, combustion and control for the diesel engine, together with optimizing the power train layout utilizing electric hybridization, downsizing and electrification of auxiliaries and alternative fuels.Research to the aftertreatment system is included to further improve the powertrain efficiency. This will be combined improvements to the base engine friction for developing highly efficient drivelines for long distance transports.CORE is divided into five sub-projects, three that will focus on different engine technologies. These activates are supported by two cross divisional projects where friction reduction and improvements to the NOx aftertreatment technologies are studied. The project results will be assessed by vehicle simulations. Results will be evaluated for legislation test cycles and in real life drive cycles. The project will demonstrate three diesel powertrains and one natural gas truck.

​Summary: The objective of the project is to promote CO2 reduction via improved powertrain efficiency, with the goal to overcome known limitations while maintaining the potential for implementation under high volume production by the end of this decade. The technical objectives are to demonstrate 15% improvement in fuel economy. Chalmers is involved in a sub-project concerning high efficiency Diesel engines for long haul trucks. Our task is to explore the potential of new combustion concepts (e.g. Partially Pre-mixed Combustion/Low Temperature Combustion). The primary goal of the task is to study the effects of various injection, EGR, and charging strategies using unconventional valve timings in order to assess how a “high efficiency combustion concept” can be realized and controlled. Particular attention will be given to EGR strategies. The robustness of the various solutions will be considered. For the experiments a heavy duty single cylinder engine equipped with a fully flexible valve system will be used. For simulations, GT-Power and KIVA 4/OpenFoam will be used.

The figure below shows rate of heat release obtained by GT-Power and KIVA 4 simulations for two different intake valve timings. One can see that ignition delay times were increased when later IVC timing was used, and a larger part of the charge was burned in a premixed mode. Temperature reduction before ignition helps in reducing NOx emissions especially for 25% EGR cases, while soot emissions decrease due to more premixed combustion with a later IVC timing.

The project includes 16 partners.

Calculated rate of heat release curves with 25% EGR for IVC 0 aBDC (baseline) and late IVC 100 aBDC cases at 50 % load and 1200 rpm (A50).
