Since 2004, SmartWay Partners have saved 144.3
These systems will also need to deliver very low criteria pollutant levels (e.g., Gains in new vehicle fleet economy by OEM, 2004-2009. Ford, however, was starting with the worst 2004 new vehicle fleet fuel economy of any of its major competitors. Electrical loading optimization design. Click to enlarge. Brake drag.
The on-road transportation (ORT) and power generation (PG) sectors are major contributors to CO 2 emissions and a host of short-lived radiatively-active air pollutants, including tropospheric ozone and fine aerosol particles, that exert complex influences on global climate. Unger et al. Click to enlarge. Unger et al. Nadine Unger, Drew T.
Large-capacity PHEVs—sized for 40 or more miles of electric-only travel—are not cost-effective in any scenario, according to the findings, although they could minimize GHG emissions for some drivers and provide potential to shift air pollutant emissions away from population centers. Shiau et al.
TRU gensets are typically engine-powered generators designed to provide power to electrically driven refrigeration units. TRUs and TRU gensets emit diesel PM, NO x , greenhouse gases and other pollutants. ARB adopted the TRU Airborne Toxic Control Measure in 2004, with amendments in 2010 and 2011, to reduce PM emissions from TRU units.
