Diesel Fuel Standard

Definition:

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.

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.
