The CORE (CO2 Reduction for Long-Distance Transport) project was a collaborative largescale integrating research activity for a call within the European Commission’s 7th Framework Programme research area for sustainable surface transport. The project consortium consisted of three truck manufactures in Europe – Volvo, Daimler and IVECO – together with Ricardo plus other partners in the automotive industry and academia. The objectives were to demonstrate a substantial reduction of CO2 emissions, improve fuel efficiency by 15% compared to a EURO V engine, and, at the same time, fulfill EURO VI emission legislation.
By using novel technologies and combining them in flexible engines with a high level of precise control, performance advantages were achieved, with improvements in emissions and fuel consumption. The research focussed on downsizing, efficient air management, combustion and control for the Diesel engine, together with optimizing the powertrain layout, utilizing electric hybridization, electrification of auxiliaries and alternative fuels.The immediate technical target of 15% fuel-consumption improvement has now been reached and demonstrated in simulation by Ricardo.
Research into 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 several sub-projects, three of which will focus on different engine technologies. These activities 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. The target fuel economy improvement of 15% is based on a EURO V state-of-the-art technology operating at the EURO VI emission standard. It is envisioned to achieve 6–9% in the sub projects, with different engines, powertrains and fuel approaches. The hybridization of the powertrain will contribute with an estimated 3–5% fuel economy improvement, dependent on the vehicle test cycle, through usage of energy recuperation during deceleration events. An additional 2–4% of fuel economy improvement is attributed to friction reduction of the combustion engine and energy efficient exhaust gas aftertreatment systems and operation. .
