Engine technology at the turn of the millennium

Since its birth, new technology has been introduced continuously to the internal combustion engine in response to constant demands for better performance, higher power density and lower fuel consumption. It is described how smaller, more flexible but also more complex engines, provided with enhanced aftertreatment systems and sophisticated engine management systems are appearing on the automotive market. A key element with these engines is better electronic control of fuel and air emission. Furthermore it is shown how, in the automotive field, more sophisticated driveline technology is interacting with the engine, leading to further powertrain optimisation. Finally, global warming impact trade-offs between future changes in engine and fuel technology are discussed
