Manufacturers continue to optimize diesel emission controls, such as DOC, DPF and SCR, in order to promote uniform catalyst coating, improve NO x conversion efficiency, reduce back pressure on the engine, and reduce thermal mass. Better catalysts and urea dosing systems can achieve high NOx conversion during lower temperature operation.
Thanks to this rightsizing approach, the new engine enjoys the consumption benefits of a downsizing engine in partial load operation, while at higher loads it has the advantages of a large-displacement engine. The result is optimal efficiency and performance characteristics across the entire engine speed range. Stroppiana, A.,
This downsizing enables lower fuel consumption, accompanied by low emissions and optimum weight. Conversely, intervention will be stopped if the driver carries out an evasive maneuver, takes his or her foot off the brake pedal or presses the accelerator pedal. The engines attain both a high specific power output and high torque.
The resulting higher BMEP levels allow downsizing of the engine at equivalent vehicle performance. Furthermore, by enabling higher CR, downsizing and downspeeding, E85 DI + gasoline PFI makes the engine more efficient in itsusee of gasoline. Earlier post.)
In addition, they found that many systems are capable of NO x conversion over a wide temperature range at rates close to those of three-way catalytic converters on gasoline vehicles. Further, as NO x conversion catalysts are improving, so are diesel particulate filters and their methods for regeneration. E-boost and 48V.
The A48 engine in Achates’ test cell was developed on an 80mm bore, Johnson said; the TARDEC application will be a bit downsized. Conversely, in a four-cylinder configuration, the gas-exchange events overlap too much. Any opposed-piston engine with a stroke/bore below 2.0 Three-cylinder configuration.
This is because the ethanol component may affect the conversion efficiency of the gasoline component in a blend, that is, make an engine more or less efficient in its use of the gasoline component. converted all vehicle efficiency measurements into vehicle energy efficiency (VEE, km/MJ) based on fuel energy densities reported in each study.
liter downsized turbocharged centrally-mounted direct injection engine. This study also showed that that catalyzed GPFs can improve the conversion efficiency for NO x , THC, and CO emissions and have no measurable impact on CO 2 emissions and fuel economy.

Auto plants around the country are in danger of downsizing or shutting down altogether, and helping these facilities to retool for EV production instead makes economic sense. To these ends, the US Department of Energy has established the Domestic Manufacturing Conversion Grant Program.
And there they would have stayed without a chance conversation and assistance from some very capable librarians and archivists. Moreover, unlike some libraries, which have downsized their journal collections in favor of electronic databases, LHL remains committed to preserving its print holdings.
