Potential for reduction of fuel consumption to meet future CO2 emission targets

Even though fuel efficiency has always been an important factor in powertrain development over the year, CO2 emissions have, thus far, not been restricted by legislation. Therefore, the major technological innovations in the past years have focused on the reduction of nitrogen oxides, particulate matter, hydrocarbon and carbon monoxide emissions. However, the introduction of CO2 emission limits for on-road engines in the USA from 2014 onwards has changed the engineering landscape, placing CO2 emissions and thereby fuel efficiency firmly in focus. In this work, the impact of a variety of technologies on the fuel efficiency of on-road commercial engines is presented. Among the technologies discussed are engine-internal measures like boosting, injection pressure and injection system, combustion system layout and down-speeding. Additionally, friction reduction measures in the engine, as well as advanced energy recovery systems are viewed regard to fuel savings. From a point of view of sustainable future mobility, under adherence of limits of currently restricted exhaust gas components, feasible combinations to meet future CO2 emission targets are proposed.
