Reducing Black Carbon Emissions and Ground-Level Ozone Would Provide Immediate Benefit Against Climate Change

Green Car Congress

AUGUST 21, 2009

Reducing emissions of black carbon soot and ground-level ozone would quickly make a considerable dent in the climate change problem and would also contribute to public health and protect crop yields, according to an essay in the September/October issue of Foreign Affairs. Besides a danger to breathe, ozone lowers crop yields.

At cruising altitude, airplanes emit a steady stream of NO x into the atmosphere, where the chemicals can linger to produce ozone and fine particulates. The trend towards smaller engine cores with smaller mass flow rates in the core stream, presents new opportunities for emissions control. increase in block fuel burn.

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.

Short-lived climate pollutants (SLCPs) include methane, tropospheric ozone, black carbon, and fluorinated gases. The Concept Paper presents initial ideas that will be considered and evaluated in the coming months by ARB staff, in coordination with other agencies, as it develops a SLCP Strategy pursuant to SB 605.

Air pollution impairs the function of blood vessels in the lungs, according to a study of more than 16,000 patients presented at EuroEcho-Imaging 2016. The volunteers were exposed to ambient air or dilute diesel exhaust with a PM 2.5 and ozone on pulmonary circulation on the same day and over five and ten days.

Exhaust from modern gasoline powered engines, despite higher ignition temperatures than those powered by diesel, can be effectively treated for NO along with NMVOC (and CO) using a three way catalytic (TWC) converter. 85% is modelled to be emitted by the passenger car fleet based on the COPERT model and TRACCS database. —Karl et al.

JANUARY 28, 2014

Compared to the 2010 “Business as Usual” scenario—which includes all adopted emission control measures for the South Coast—NO x levels must be reduced by 65% and by 75% to meet the 2023 and 2032 ozone standards, respectively. All totaled, engine heat accounts for 26% of the fuel consumed, and exhaust heat accounts for another 24%.

The chemistry of a fuel impacts the emissions from an engine, with the most obvious example being unburned or partially burned fuel which is a major component of engine exhaust. Engine-out exhaust contains typically 1?3% via the unburned or partially burned fuel which is a major component of engine exhaust. —Hubbard et al.
