What is EN 590:2013?

EN590:2013 is a technical standard that specifies the requirements for automotive diesel fuel. It was first introduced in 1993 by the European Committee for Standardization (CEN) and has seen updates since then, with the latest version being EN590:2013.

The Importance of EN590:2013

EN590:2013 plays a crucial role in ensuring the quality and performance of diesel fuel used in vehicles. It sets the standards for various parameters including sulfur content, viscosity, cetane number, and cold flow properties, among others. Compliance with these specifications helps to prevent engine damage, optimize fuel efficiency, and reduce harmful emissions.

Main Specifications of EN590:2013

The key specifications outlined in EN590:2013 include:

Sulfur Content: The standard restricts the maximum sulfur content to 10 parts per million (ppm) for on-road diesel fuels. This low sulfur content helps reduce particulate matter emissions, which are harmful to both human health and the environment.

Viscosity: EN590:2013 sets limits on the kinematic viscosity range of diesel fuel to ensure proper fuel delivery and combustion in engines. The specified range allows for optimal atomization of the fuel spray, preventing injector clogging and combustion issues.

Cetane Number: This represents the ignition quality of the fuel. EN590:2013 requires a minimum cetane number of 51, which ensures good cold starting capability and efficient combustion, resulting in smoother engine operation.

Cold Flow Properties: The standard includes requirements for diesel fuel's ability to resist gelling and maintain fluidity at low temperatures. These properties are essential to prevent fuel filter plugging and ensure reliable engine performance in cold climates.

Conclusion

EN590:2013 is a vital technical standard that ensures the quality, performance, and environmental compatibility of automotive diesel fuel. Its strict requirements regarding sulfur content, viscosity, cetane number, and cold flow properties help to safeguard engines, improve fuel efficiency, and reduce harmful emissions. Compliance with EN590:2013 is essential for both automobile manufacturers and fuel suppliers to guarantee optimal vehicle performance and minimize the impact on our environment.
