50 ppm sulfur content was first legislated by the South African Department of Minerals and Energy in early 2006, and has been widely available since then. South Africa's Clean Fuels 2 standard, expected to have begun in 2017, reducing the allowable sulfur content to 1 ppm. As of 2013, Sasol launched 10 ppm diesel at selected filling stations. [14]
The limit was lowered with the introduction of Euro 4 by 2006 to 50 ppm (ULSD, Ultra Low Sulfur Diesel). The standard for diesel fuel in force in Europe as of 2009 is the Euro 5, with a maximum content of 10 ppm.
British Rail Class 55 Deltic diesel locomotive with their characteristic dense exhaust when starting a train. Diesel exhaust is the exhaust gas produced by a diesel engine, plus any contained particulates. Its composition may vary with the fuel type, rate of consumption or speed of engine operation (e.g., idling or at speed or under load), and ...
The EN 590 had been introduced along with the European emission standards.With each of its revisions the EN 590 had been adapted to lower the sulphur content of diesel fuel – since 2007 this is called ultra-low-sulphur diesel as the former function of sulphur as a lubricant is absent (and needs to be replaced by additives).
Sulfur content in gasoline was limited to an average of 120 parts-per-million (maximum 300 ppm) in 2004, and this was reduced to an average 30 ppm (maximum 80 ppm) for 2006. Ultra-low sulfur diesel began to be restricted to a maximum 15 ppm in 2006 and refiners are to be 100% compliant with that level by 2010.
To get the maximum 50/50 note on this cycle, the car shall emit less than the minimum limit applicable to either petrol or diesel car, that is to say 100 mg HC, 500 mg CO, 60 mg NO x, 3 mg PM and 6 × 10 10 PN. Unlike ambient discourse dirty diesel versus clean petrol cars, the results are much more nuanced and subtle.
Diesel exhaust is the exhaust gas produced by a diesel engine, plus any contained particulates. Its composition may vary with the fuel type, rate of consumption or speed of engine operation (e.g., idling or at speed or under load), and whether the engine is in an on-road vehicle, farm vehicle, locomotive, marine vessel, or stationary generator ...
Diesel and gasoline sulphur content is regulated at 10 ppm. [46] Turkey currently follows Euro VI for heavy duty commercial vehicles, [47] and, in 2016 a couple of years after the EU, Turkey adopted Euro 6 for new types of light duty vehicles (LDV) and new types of passenger cars. [48]
