How is Low Sulphur Diesel different from regular diesel?
Low sulphur diesel is an environmentally friendly reformulated diesel fuel that helps people who drive diesel-powered vehicles protect the environment. Exhaust emissions are virtually Sulphur-free (98% lower than ordinary Diesel) and Particulate and Nitrogen Oxide emissions are reduced considerably. Pedestrians also notice the difference as the quality of city air improves and the smell of exhaust gases decreases. The sulphur content in diesel is directly linked to the production of exhaust particulate matter (visible as black smoke). Cleaner engines that meet low exhaust emission standards therefore require fuels with low sulphur contents. Sulphur content is also linked to the lubricating properties of the fuel. Low sulphur fuels may require additives to provide lubrication to fuel pumps and injection systems. If necessary, these would be added at the refinery.
