powertrain engineering TRUE TOP PERFORMANCE Building on AVL’s comprehensive expertise in turbocharged gasoline engines, AVL and Volvo teamed up to develop a 450 hp concept engine, producing 228 hp for every liter of engine displacement (168 kW/l). This is the highest liter output ever to be achieved by a four-cylinder engine. The electrically driven compressor has been at the center of a number of engineering projects, in which AVL has accumulated vast experience. The technology is deployed to adapt the high-performance engine’s torque characteristics to suit the requirements get behind the wheel of an S60 demonstrator car and find out for themselves what the technology can deliver. 1 0 F O C U S of everyday operation. Participants of the Aachen Colloquium had the chance to closer to optimum fuel consumption. Turbocharging can also help to produce a full load curve with a constantpower characteristic. “These two factors – load point shifting and the greater range over which the power is available – are crucial to the success of downsizing or rightsizing in gasoline With gasoline engines, higher power densities are on the rise. “Although the average engine output of 65-75kW/l in the mass segment is relatively moderate, or even stagnating, there is a trend towards higher and higher power densities in gasoline engine development,” explains Paul Kapus, Head of Gasoline Engine Development at AVL. The smaller turbocharged engines used for downsizing are operated at a specifically higher load, bringing them > Volvo S60 demonstrator vehicle with 450 hp engine
