Diesel Fuel

Diesel fuel is a type of petroleum-based fuel that is commonly used in diesel engines. It is made from crude oil and has a higher energy density than gasoline, which makes it more efficient and better suited for heavy-duty vehicles.

EN 590 Diesel Fuel Specifications (ULSD)

Diesel fuel EN590 is a standard that specifies the requirements for diesel fuel used in diesel engines with compression ignition. It sets limits on the properties such as sulfur content, density, flash point, cetane number, and more.

EN 590 Gas Oil Specifications:

what physical properties does EN 590 diesel have? What are the fuel’s chemical properties?

Gas Oil meets BS 2869 (2010) Class A2 and the EN590 specification. Gas oil is a dyed and marked product, to be used for small furnace or boiler applications, stationary diesel and untaxed engines. Crown Oil supplies red diesel that meets EN 590 standards.
For diesel fuel to meet EN 590 specifications, it means that the fuel must have the required physical and chemical properties that the standard requires. The table below shows the physical properties and chemical properties that the EN 590 standard requires, as well as how the fuel meets these characteristics.
