ORNL researchers quantify the effect of increasing highway speed on fuel economy

Green Car Congress

legal light-duty vehicles from 1984 to present. One tip is that drivers should obey the speed limit since the fuel economy of most vehicles decreases above 50 mph [80 km/h]. Vehicles were tested in dynamometer laboratories at steady speeds from 40 to 80 mph [64 to 129 km/h], with the proper road-load applied. 50 to 60 mph.

Nonthermal plasma torch reforming of exhaust gas for NOx trap regeneration

Green Car Congress

Researchers from the Center for Energy and Processes (CEP), MINES ParisTec, and Renault are exploring the non-catalytic reforming of diesel fuel with diesel engine exhaust gas (i.e. An alternative to the catalytic exhaust gas reforming of diesel fuel method is presented in this paper and consists of using an NTP torch. trap catalyst.
