Verified Diesel Emission Reduction Technologies and Their Outcomes
- Biodiesel: Reduced inorganic ( soot)carbon emissions, Increased NOx emissions - Increased organic carbon ( SOF / VOC ) emissions.
- Diesel Particulate Filter ( various manufacturers ): Reduces TPM, Does Not Address NOx.
- Diesel Oxidation Catalyst( various manufacturers) : Reduces TPM, Does Not Address Nox.
- Clean Diesel Technologies fuel borne catalyst: potential fine metallic emissions & potential resulting health effects - need PM filter - minimal Nox reduction.
- Purinox - water / diesel fuel emulsion: PM/HC/CO emissions can increase as a result of tuning to compensate for decreased power- only summer blend verified
- Envirofuels Diesel Fuel Catalyzer: verified on tier 0 locomotive engine - verification report specifies an increase in total particulate( TPM ) emissions on the treated fuel, as compared to the baseline fuel, even though the gaseous emissions and visible smoke opacity decreased significantly.
- Envirofuels diesel fuel catalyzer showed a verified fuel consumption reduction
of 5% during "line haul duty", but the % of error was + / - 4%, and under the heaviest load, there was no reading given for fuel consumption reduction. The Envirofuels verification report indicates that TPM increased as little as 40%, and as much as 170%. Envirofuels Diesel Fuel Catalyzer, while "verified', actually increased TPM emissions, and showed what amounts to an inconclusive result for fuel use reduction.

Famous quotes containing the words verified, emission and/or reduction:
“Essential truth, the truth of the intellectualists, the truth with no one thinking it, is like the coat that fits tho no one has ever tried it on, like the music that no ear has listened to. It is less real, not more real, than the verified article; and to attribute a superior degree of glory to it seems little more than a piece of perverse abstraction-worship.”
—William James (1842–1910)
“Approximately 80% of our air pollution stems from hydrocarbons released by vegetation, so let’s not go overboard in setting and enforcing tough emission standards from man-made sources.”
—Ronald Reagan (b. 1911)
“The reduction of nuclear arsenals and the removal of the threat of worldwide nuclear destruction is a measure, in my judgment, of the power and strength of a great nation.”
—Jimmy Carter (James Earl Carter, Jr.)
