EN590 is the European standard for diesel fuel that outlines specific technical requirements and characteristics to ensure the quality and compatibility of diesel fuels used in road vehicles.
EN590
You are here:
Composition and Properties
Sulfur Content: EN590 sets limits on sulfur content, aiming to reduce emissions and air pollution. Ultra-low sulfur diesel (ULSD) with sulfur content typically not exceeding 10 parts per million (ppm) is a common requirement.
Density and Viscosity
Specifies acceptable density and viscosity ranges to ensure proper combustion and engine performance.
Cetane Number
Defines the minimum cetane number, which indicates the ignition quality of the diesel fuel. Higher cetane numbers generally result in better combustion.
Distillation Characteristics
Specifies distillation temperature ranges to ensure that the fuel evaporates and ignites within optimal engine conditions.
Cold Flow Properties
Addresses cold weather performance, including cloud point and cold filter plugging point, to prevent fuel gelling in low temperatures.
Compliance with European Emission Standards
EN590 aligns with European emission standards, supporting the use of advanced emission control technologies in diesel engines to reduce pollutants.
Biodiesel Blending
The standard allows for the blending of diesel with biodiesel, up to certain specified percentages, promoting the use of renewable fuels and addressing environmental concerns.
Quality Assurance
EN590 ensures consistent fuel quality by establishing testing methods and quality control measures. Compliance with these standards helps maintain the efficiency and reliability of diesel engines.
Regulatory Compliance
Diesel fuels meeting EN590 standards are widely accepted in European countries and are often required for use in modern diesel engines.
Future Developments
Standards may evolve to address emerging technologies, environmental concerns, and changes in the automotive industry, ensuring that diesel fuels remain compatible with modern engines.
