Abstract
Compared to diesel engines, turbocharged direct-injection petrol engines are an economical alternative for reducing CO2 emissions from vehicles. The possibilities and limitations of downsizing an exhaust gas turbocharged four-cylinder petrol engine were investigated at the Chair of Combustion Engine Technology at the Technical University of Dresden. It was found that the success of turbocharged, consumption-optimised engines depends not only on the choice of a suitable turbocharger system to match the engine concerned but also on having the right number of cylinders to match the turbocharger system. The increased ignition intervals mean that, in some cases, three-cylinder engines may offer a better dynamic response than four-cylinder units.
