Diesel EN590 refers to a specific grade of diesel fuel that meets the European standard EN 590. This standard specifies the requirements for automotive diesel fuels in Europe, ensuring consistency and quality across the market.

• Automotive Engines: Diesel EN590 is used in modern diesel engines for cars, trucks, and buses. Its low sulfur content helps to protect engine components and reduce emissions.
• Industrial Use: It can also be used in industrial diesel engines and machinery, providing efficient and reliable performance.

• European Regulations: EN590 is a European standard, so diesel fuel that meets this specification is generally used across EU countries and other regions following similar standards.
• Environmental Compliance: The ultra-low sulfur content of EN590 diesel fuel helps to meet stringent environmental regulations aimed at reducing air pollution and improving air quality.

• Cetane Number: The cetane number of EN590 diesel fuel must be at least 51. This rating measures the fuel’s ignition quality and is important for smooth engine performance and reduced emissions.
• Sulfur Content: EN590 specifies a maximum sulfur content of 10 parts per million (ppm), which is known as Ultra Low Sulfur Diesel (ULSD). This low sulfur content helps to reduce harmful emissions and is crucial for compliance with environmental regulations.
• Density: The density of EN590 diesel fuel is typically between 820 and 845 kg/m³ at 15°C. This density range ensures proper combustion and engine performance.
• Flash Point: The minimum flash point (the temperature at which the fuel can vaporize to form an ignitable mixture in air) is 55°C. This is important for safety during storage and handling.
• Cold Filter Plugging Point (CFPP): EN590 diesel fuel must meet specific requirements for its CFPP, which indicates the lowest temperature at which the fuel will flow through a filter. This is essential for ensuring that the fuel remains usable in cold weather conditions.
• Viscosity: The viscosity of EN590 diesel fuel is specified to ensure proper engine lubrication and fuel pump function. It typically ranges from 2.0 to 4.5 mm²/s at 40°C.
• Additives: EN590 diesel fuel may contain various additives to improve its performance, such as lubricity additives to protect the fuel system and detergents to keep the engine clean.
