ALABC: 48V mild hybrids can meet emission targets with CO2 reductions of 15-20%

Green Car Congress

The T-Hybrid (based on a Kia Optima) ( earlier post ) and the ADEPT (based on a Ford Focus) ( earlier post ) both utilize an advanced 48V lead-carbon battery system with bolt-on electrical components that allow for significant engine-downsizing without loss in performance. liter engine the performance of a 1.8

MECA report finds additional NOx emission reductions from new heavy-duty trucks achievable and cost-effective

Green Car Congress

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.

Audi introduces new high-efficiency 2.0L TFSI based on Miller cycle; 190 hp, 47 mpg

Green Car Congress

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 consistent reduction of friction as well as the use of low-friction engine oil (0W-20) also increases efficiency.

2014 Sprinter van for US standard with new 2.1L diesel; new driver assistance features

Green Car Congress

This downsizing enables lower fuel consumption, accompanied by low emissions and optimum weight. This results in faster heating-up of the oil, therefore minimizing frictional losses after cold starting. Charging takes place at all times via a two-stage exhaust-gas turbocharger system.

Ford E85 Direct Injection Boosting Study: A Less Expensive Alternative to Diesel

Green Car Congress

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.) Bromberg, J.B.
