Reduction in diesel carbonyl emissions using F-T fuel from coal

Green Car Congress

Other research has shown that carbonyls directly influence physiological response to diesel exhaust particles and can also contribute to secondary organic aerosol formation. However, the use of CFT resulted in a remarkable reduction in carbonyl emissions in comparison with using DF. Jakober, 2008). In addition, there was an 18.0–35.8%

HEI study finds London Congestion Charging Scheme shows little evidence of improving air quality

ppb on average; the investigators attributed this increase to higher NO 2 emissions associated with the introduction of particle traps on diesel buses as part of Transport for London’s improvements in the public transport system. NO 2 was projected to increase slightly, by 0.3 —Kelly et al. Resources.

OptiFuel finalizing $2.6M DOE grant to demonstrate RNG hybrid line-haul locomotive

Green Car Congress

In the next 2 years, OptiFuel will be announcing additional refueling products, including an affordable 12,000 DGE (Diesel Gallon Equivalent) CNG/RNG tender; and a 9,000 CNG/RNG DGE, 1,600 hp zero emission, powered tender. In comparison, OptiFuel’s 4,300 RNG hybrid line-haul locomotive is expected to emit 0.04 g/bhp-hr of PM.

Comparative study finds that B20 increases emission rates of a number of pollutants in both light- and medium-duty diesel engines at idle

Green Car Congress

L) diesel engines at idle and load, using a biodiesel blend (B20) and conventional ultralow sulfur diesel (ULSD) fuel. They found that the level of emissions of regulated and unregulated pollutants in diesel exhaust depends on fuel, load, engine calibration, and exhaust aftertreatment technology.

Study finds climate impact of long distance trip can vary by factor of 10 depending upon mode, efficiency and occupancy

Green Car Congress

A notable exception is for the small diesel car; with two passengers ( i.e., 50% occupancy), the specific climate impact is lower than for an average train or bus trip. Similar effects apply for diesel buses, but because of their higher unit emissions of BC and NO x , the contribution of SLCFs is more pronounced. fuel consumption.
