EN590 diesel is a standard specification for diesel fuel in the European Union and other countries that adhere to European standards. It sets the requirements for the properties of diesel fuel used in road vehicles with diesel engines. Here's a brief description of EN590 diesel:
Sulfur Content: EN590 typically mandates low sulfur content, usually less than 10 parts per million (ppm). Low sulfur content helps reduce harmful emissions such as sulfur dioxide, which contributes to air pollution and acid rain.
Cetane Number: EN590 specifies a minimum cetane number, which indicates the ignition quality of the diesel fuel. Higher cetane numbers generally result in better engine performance, smoother combustion, and lower emissions.
Density and Viscosity: The standard sets limits on the density and viscosity of the diesel fuel. Proper density and viscosity ensure optimal engine performance and fuel efficiency.
Distillation Properties: EN590 diesel must meet certain requirements regarding its distillation characteristics, ensuring that the fuel evaporates and combusts effectively within the engine.
Cold Flow Properties: The standard includes specifications for the cold flow properties of diesel fuel, such as the cloud point and the cold filter plugging point. These properties are crucial for preventing fuel gelling and ensuring engine operability in cold weather conditions.
Water and Sediment Content: EN590 limits the amount of water and sediment that diesel fuel can contain, as excessive levels can lead to engine problems and fuel system corrosion.
Additives: While not explicitly detailed in the EN590 specification, diesel fuel may contain additives to enhance performance, improve lubricity, prevent corrosion, or address specific environmental concerns.
Overall, EN590 diesel is designed to meet stringent quality and environmental standards, ensuring reliable and efficient operation of diesel engines while minimizing harmful emissions and environmental impact.
