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.

ORNL study quantifies fuel economy costs of common driver practices and vehicle alterations

Green Car Congress

The results for the SUV pulling a 3,500 pound enclosed cargo trailer were significant, resulting in FE penalties ranging from 30%, for the city cycle, to 50% at 80 mph (129 km/h), at which point significant CO generation indicated protective enrichment due to high load. l/100 km) at 60 mph (97 km/h) to 33 mpg (7.1 l/100km); and.

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

Green Car Congress

One tip is that drivers should obey the speed limit since the fuel economy of most vehicles decreases above 50 mph [80 km/h]. ORNL staff members John Thomas, Shean Huff and Brian West have worked to quantify this trend through analysis of dynamometer testing results for 74 vehicles at steady-state speeds from 50 to 80 mph [80 to 129 km/h].

Toyota Central R&D developing free-piston engine linear generator; envisioning multi-FPEG units for electric drive vehicles

Green Car Congress

Toyota envisions that a pair of such units (20 kW) would enable B/C-segment electric drive vehicles to cruise at 120 km/h (75 mph). Burned gas is scavenged out through exhaust valves mounted in the cylinder head of the combustion chamber; fresh air is brought in through the scavenging port at the side wall of the cylinder liner.

UCLA, ARB, WVU measure on-road particle numbers for heavy-duty diesel and CNG trucks in California

Green Car Congress

In a new study, a team from UCLA, with colleagues from the California Air Resources Board (ARB) and West Virginia University, measured total particle number emission factors (PNEFs) from six newly certified heavy-duty vehicles (HDVs) powered by diesel and CNG totaling over 6,800 miles of on-road operation in California.
