摘要

Concerns regarding global warming and energy security have increased the importance of decreasing emissions of CO_2 from vehicles. Diesel vehicles have higher fuel economy and lower CO_2 emissions than their gasoline counterparts. On a well-to-wheels per vehicle per km basis it has been estimated that diesel light-duty vehicles in 2015 will emit 14-27% less CO_2 than their gasoline counterparts. We estimate here that on a gCO_2/kWh at peak torque, diesel medium-duty vehicles currently have an approximately 10% CO_2 advantage over their gasoline counterparts. At light and moderate loads the CO_2 advantage for medium-duty diesels with SCR after-treatment will be greater than 10% (reflecting pumping losses when gasoline engines are operated at low and moderate loads). Emission of NO_x, HCs, and PM from diesel (and gasoline) vehicles has decreased substantially over the past decade and further reductions are anticipated in the future. In addition to the heavy-duty segment, which diesels currently dominate, modern diesel engines are likely to continue to play an important role in the medium-duty segment, and perhaps also in the light-duty segment in a transition to more sustainable mobility.
