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. In the Tianjin study, they team fueled a four-cylinder light-duty diesel engine fueled with CFT and DF, identifying 13 individual carbonyl compounds in the exhaust.

GISS study finds applying stricter non-CO2 vehicle emission standards worldwide would yield climate benefits in addition to major health and agricultural benefits

Green Car Congress

Climate response to non-CO 2 vehicle emissions. vehicle emissions under the baseline scenario (a) and the difference between the tight-standard and baseline scenarios (b). However, these standards will not reduce CO 2 emissions, which is required to mitigate long-term climate change, the team notes. Shindell et al.

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

Green Car Congress

Kelly and his team used a multifaceted approach to explore the impact of the Congestion Charging Scheme on air quality: a variety of emissions and exposure modeling techniques, analysis of air monitoring data, and a newly developed assay for the oxidative potential of particulate matter collected on filters at urban background and roadside monitors.

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

Green Car Congress

The program will demonstrate that a suite of commercially available, EPA-rail-certified engines present a near-term, low-risk solution to create an affordable RNG hybrid line-haul locomotive with near zero emissions while simultaneously improving fuel cost by 50%. g/bhp-hr of NOx, a reduction of 400 times. g/bhp-hr of PM.
