What is EN 590 2013?

The EN590 2013 is a technical standard that specifies the requirements for automotive diesel fuel in European countries. This standard was introduced in 1993 and has since gone through several revisions to ensure the quality and compatibility of diesel fuel used in vehicles. The most recent version, EN590 2013, sets the benchmark for diesel fuel across Europe.

Quality and Performance

EN590 2013 defines various parameters and limits that diesel fuel must meet to ensure its quality and performance. These parameters include cetane number, density, sulfur content, flash point, and lubricity. Cetane number measures the combustion quality of the fuel, while density affects its energy content. Sulfur content is an important environmental concern as it contributes to air pollution. Flash point indicates the temperature at which the fuel can ignite, and lubricity determines the ability of the fuel to lubricate fuel system components.

Environmental Impact

EN590 2013 places a significant emphasis on reducing the environmental impact of diesel fuels. One of the key requirements is the limitation of sulfur content to a maximum of 10 parts per million (ppm). This low sulfur content helps in minimizing emissions of sulfur dioxide (SO2), a major contributor to air pollution. Additionally, the standard also sets limits for aromatic hydrocarbons, which are known to have harmful effects on human health and the environment.

Compatibility with Modern Engines

With advancements in engine technology, diesel engines have become more sophisticated and efficient. EN590 2013 takes into account these developments and ensures that diesel fuel is compatible with modern engines. The standard includes specifications for biodiesel blending up to 7% (B7), which promotes the use of renewable fuels without compromising engine performance and durability. This allows for a smooth transition to cleaner energy sources while maintaining the reliability of diesel-powered vehicles.
