D2 Diesel Gas Oil Explained
D2, short for Gasoil, represents the second distillate derived from crude oil. Initially used in engines before the advent of petrol cars, D2 doesn't require spark plugs, owing to Rudolf Diesel's engine design. Today's diesel engines still operate on similar principles, relying on compression ignition.
Additives and Winterization
Automotive diesel, unlike raw D2, undergoes refinery-added additives for enhanced efficiency and cold weather performance. These additives modify its flash point and improve water absorption to prevent issues like freezing fuel pipes.
Sulphur Content and Evolution
One significant difference between GASOIL and D2 lies in their sulphur content. Over the years, regulatory bodies like the US EPA and European standards have imposed increasingly stringent sulphur limits. From 4% in the past, sulphur content in modern D2 is now well below 0.2%, with "Ultra Low Sulphur" variants reaching as low as 0.02%.
Standards and Specifications
ISO sets the standard for D2, while national variants exist in regions like the US (ANSI), Europe (DIN), and Russia (GOST). These standards define parameters like sulphur content, ensuring uniformity and quality across the industry.
Impact on Pollution and Transportation
Reducing sulphur in gasoil has led to decreased pollution in urban areas. Moreover, automotive diesel variants like EN590 and EN560, compliant with ISO standards, are being tested in planes for increased fuel efficiency and reduced emissions. However, challenges like condensation, ice formation, and wax deposits need innovative solutions for broader adoption in aviation.
The Future of Diesel Fuels
As efforts to reduce emissions intensify, the aviation industry may transition to gasoil-based fuels for improved efficiency. Solutions like preheating and filtration are being explored to address technical challenges and pave the way for a cleaner, more sustainable future in transportation.
