D2 Diesel Fuel Overview

D2 Diesel is a standard grade of gasoil (diesel fuel) commonly used for automotive, industrial, and power generation applications. It is heavier and less refined than D1 diesel, making it more energy-dense but less suitable for extremely cold climates.

Key Features of D2 Diesel:

• Sulfur Content:
• Traditional D2 diesel contained up to 500 ppm of sulfur.
• Modern Ultra-Low Sulfur Diesel (ULSD) variants contain a maximum of 10-15 ppm to meet environmental regulations.
  
  
• Cetane Number:
• Typically 45-51, ensuring efficient combustion in diesel engines.
  
  
• Density:
• 850-870 kg/m³ at 15°C, making it denser than D1 diesel.
  
  
• Flash Point:
• Above 60°C, ensuring safety in transport and storage.
  
  
• Cold Flow Properties:
• Can gel in extreme cold, making it unsuitable for subzero temperatures without additives or blending with D1 diesel.

Uses of D2 Diesel:

• Automobiles & Trucks: The most common diesel fuel for road vehicles in many parts of the world.
• Industrial Machinery: Used in construction, mining, and manufacturing industries.
• Power Generation: Often used in diesel generators and backup power systems.
• Marine Fuel: Some marine engines use D2 diesel, though Marine Gas Oil (MGO) is often preferred.

D2 Diesel Variants:

D2 vs. EN590 Diesel:

• D2 Diesel is widely used globally but contains more sulfur than EN590, which follows stricter European environmental standards.
• EN590 is usually ultra-low sulfur diesel (ULSD), making it more suitable for newer diesel engines with emission control systems.

Availability & Trade:

• Common Suppliers: Russia, Middle East, USA, Europe, and Asia.
• Traded in Metric Tons or Barrels, and pricing depends on crude oil costs, refining margins, and global demand.
