Starting in 2006, Ultra Low Sulfur Diesel (ULSD) began replacing conventional diesel fuels. ULSD contains 97% less sulfur than conventional diesel and effectively reduces sulfur from 500 parts per million (ppm) to 15 ppm. ULSD is a cleaner burning fuel and produces less particulate matter in both new and old diesel engines.
In addition, ULSD will allow manufacturers to make use of improved emissions treatment devices that could not have been used, due to the destructive nature of sulfur, with conventional diesel fuels. The aforementioned treatment devices are capable of further reducing particulates and smog forming nitrogen oxides (NOx).
Emissions Treatment Devices
·Particulate Traps collect particulate matter from the exhaust stream prior to discharge. These traps can effectively reduce particulate emissions by up to 90%.
·Catalytic Converters make use of a chemical reaction in order to convert emissions, such as NOx, into harmless substances. Catalytic Converters can reduce NOx emissions by as much as 50%.
Furthermore, there is a significant reduction in total emissions and could reduce current truck and bus emissions by 90%, assuming the entire fleet were replaced today. When comparing ULSD to gasoline, there is a 30% average increase in efficiency, which would result in reduced fossil fuel consumption and reduced greenhouse gas emissions.
Now, we are not promoting ULSD as the be all end all, but like some of the other technologies, it is a step in the right direction. Anything that we can do to reduce consumption and demand for fossil fuels, which directly impacts levels of greenhouse gas emissions, is positive for us and the environment.
