2. Diesel exhaust fluid - Wikipedia

   en.wikipedia.org/wiki/Diesel_exhaust_fluid

   Diesel exhaust fluid (DEF; also known as AUS 32 and marketed as AdBlue[ 3 ]) is a liquid used to reduce the amount of air pollution created by a diesel engine. Specifically, DEF is an aqueous urea solution made with 32.5% urea and 67.5% deionized water. DEF is consumed in a selective catalytic reduction (SCR) that lowers the concentration of ...

   en.wikipedia.org/wiki/Cetane_improver

   Cetane improver. A cetane improver [′sē‚tān im′prüv·ər] is a chemical which has the effect of increasing a diesel fuel 's cetane number. A few examples are nitrates, nitroalkanes, nitrocarbonates and peroxides. One of the main cetane improver additives manufactured today is 2-ethylhexyl nitrate (CAS n°: 27247-96-7) [1] which starts ...

   Fuel additives in the United States are regulated under section 211 of the Clean Air Act (as amended in January 1995). The Environmental Protection Agency (EPA) requires the registration of all fuel additives which are commercially distributed for use in highway motor vehicles in the United States, [8] and may require testing and ban harmful additives.

5. Winter diesel fuel - Wikipedia

   en.wikipedia.org/wiki/Winter_diesel_fuel

   In North America, gas stations offer two types of diesel fuel – according to ASTM D975 [5] these are named No. 1 and No. 2 fuel. No. 1 fuel (similar to kerosene) has a natural CFPP of -40 °C but it is more expensive than No. 2 fuel. Adding No. 1 fuel will lower the CFPP of No. 2 fuel – adding 10% will lower the CFPP temperature by about 5 ...

6. Diethyl carbonate - Wikipedia

   en.wikipedia.org/wiki/Diethyl_carbonate

   It has been proposed as a fuel additive to support cleaner diesel fuel combustion because its high boiling point might reduce blended fuels' volatility, minimizing vapor buildup in warm weather that can block fuel lines. [7] As a fuel additive, it can reduce emissions such as volatile organic compounds, CO 2, and particulates. [8]

7. Tetraethyllead - Wikipedia

   en.wikipedia.org/wiki/Tetraethyllead

   Tetraethyllead (commonly styled tetraethyl lead), abbreviated TEL, is an organolead compound with the formula Pb (C 2 H 5) 4. It was widely used as a fuel additive for much of the 20th century, first being mixed with gasoline beginning in the 1920s. This "leaded gasoline" had an increased octane rating that allowed engine compression to be ...
