Jet A-1 fuel is a kerosene-based aviation turbine fuel used in commercial and military aircraft. It has a minimum flash point of 38C and a maximum freezing point of -47C, ensuring safety and performance at high altitudes. It meets international standards like ASTM D1655 and DEF STAN 91-091, with additives to enhance stability, conductivity, and corrosion resistance. EN590 diesel fuel is a low-sulfur automotive diesel that meets European standards for use in diesel engines. It has a cetane number of at least 51, a sulfur content below 10 ppm, and a flash point above 55C, ensuring efficient combustion and reduced emissions. EN590 complies with Euro 5 and Euro 6 regulations, optimizing fuel economy and engine performance while minimizing environmental impact. D6 fuel oil, also known as Residual Fuel Oil or Bunker Fuel, is a heavy, high-viscosity petroleum product used primarily in industrial boilers, power plants, and large marine engines. It has a high sulfur content (up to 3.5%) and requires preheating for proper combustion due to its thick consistency. D6 is less refined than diesel and jet fuels, making it a low-cost, high-energy fuel suited for large-scale applications. D2 diesel fuel is a mid-distillate petroleum product used in diesel engines, meeting ISO 8217 and ASTM D975 standards. It has a cetane number of at least 51, a sulfur content of up to 500 ppm (Low Sulfur) or 10 ppm (Ultra-Low Sulfur - ULSD), and a flash point above 52�°C, ensuring efficient combustion and reduced emissions. D2 is widely used in transportation, agriculture, and industrial applications due to its reliability and energy efficiency.
