Diesel EN 590 is a standardized diesel fuel formulated to meet stringent quality and environmental standards set by the European Committee for Standardization (CEN) that specifies the requirements for diesel fuel used in diesel engines. It is commonly used in Europe and many other countries around the world today. EN 590 diesel has specific properties and characteristics to ensure it meets environmental and performance standards.
This is one of the most significant parameters in EN 590. It
determines the level of sulfur allowed in diesel fuel, which affects emissions and
environmental impact. The standard has undergone revisions over the years to
reduce sulfur content for cleaner emissions. The most recent version of EN 590
sets the maximum sulfur content at 10 parts per million (ppm) for ultra-low sulfur
diesel (ULSD).
This measures the ignition quality of the diesel fuel. A higher
cetane number indicates better ignition characteristics and smoother engine
operation.
This refers to the mass per unit volume of the diesel fuel. It affects fuel
efficiency and combustion characteristics.
EN 590 specifies the temperature at which certain
percentages of the diesel fuel evaporate (e.g., 10%, 50%, and 90% distilled).
This helps ensure proper engine performance across a range of operating
conditions.
These include parameters such as cloud point and cold
filter plugging point (CFPP), which determine the ability of the diesel fuel to flow
at low temperatures without causing issues such as wax precipitation or filter
clogging.
This type of diesel fuel has a maximum sulfur
content of 10 ppm, as specified in the latest version of EN 590. ULSD is widely
used in modern diesel engines to comply with stringent emissions regulations
and to reduce environmental impact.
This refers to diesel fuel with sulfur content higher
than ULSD but still lower than traditional diesel fuel. LSD typically has sulfur
content ranging from 10 to 500 ppm.
This is traditional diesel fuel with sulfur content higher than
500 ppm. It is less common today due to environmental concerns and stricter
emissions regulations.
Compared to other fuels, Diesel EN 590 offers several key advantages:
