Within the EU / Horizon 2020 funded project “REWARD”, Volvo Cars and AVL developed a High Performance Engine concept based on Volvo´s 2.0 l 4-cylinder engine architecture. The power output is increased to over 100 kW / liter by simultaneously reducing fuel consumption by 5% compared to Best In Class D/E class vehicles 2014 and achieving EU7 emission levels. A completely new “Zero-Swirl” combustion concept was developed with a rather straight intake port geometry and a stepped piston bowl concept. Increased injection pressure of up to 3000 bar and fast, accurate injection control allows optimal spray conditions. The charging concept is based on a permanent operating 2-stage turbo system with water cooled air intercooler to achieve the peak power level. It is supported by an electrical compressor for low end torque and response improvement. Furthermore, the Exhaust Aftertreatment System was optimized to achieve the challenging NOx targets and reducing exhaust back pressure to enable the high performance target. All results will be demonstrated in a Volvo XC60 to verify the fuel consumption and emission targets in both WLTC and in real driving conditions.
