"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 powertrain 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."
