Ways to reduce nitrogen oxide emissions In order to comply with the increasingly tough emission standards worldwide, engine manufacturers are forced not only to substantially reduce emissions of particulate matter (PM), but also emissions of nitrogen oxides. The main approach pursued by MTU is low-emission combustion, in other words an internal engine solution. However, this means taking into a...
The competition to deliver fuel e cient and environmentally friendly vehicles is driving the automotive industry to consider ever more complex powertrain systems. Adequate performance of these new highly interactive systems can no longer be obtained through traditional approaches, which are intensive in hardware use and nal control software calibration. This paper explores the use of dynamic pr...
Future light duty vehicles in Europe and the United States are required to be certified, owing progressively more stringent regulations [...]
The abatement of the pollutants deriving from diesel engines in vehicle sector still represents an interesting scientific and technological challenge due to increasingly limiting regulations. Meeting stringent limits NOx soot emissions requires a catalytic system with great complexity, size units, number as well increased fuel consumption. Thus, after-treatment device for use integrated catalys...
1 The fuel economy and emissions of both conventional and hybrid buses equipped with emissions 2 aftertreatment were evaluated via computational simulation for six representative city bus drive cycles. 3 Both series and parallel configurations for the hybrid case were studied. The simulation results indicate 4 that series hybrid buses have the greatest overall advantage in fuel economy. The ser...
