1. What It Is: ULSD Euro 5 (10 ppm) is a high-grade diesel fuel with maximum 10 parts per million sulfur, designed to meet the Euro 5 emissions standard. It's used in modern diesel engines with advanced emission control systems (like DPF and SCR).
2. Key Specifications (Typical Euro 5 / EN590 Compliant):
- Sulfur Content: Max 10 ppm
- Cetane Number: Min 51
- Density @15°C: 820–845 kg/m³
- Flash Point: Min 55°C
- Viscosity @40°C: 2.0–4.5 mm²/s
- CFPP (Cold Filter Plugging Point): - Summer: Max +5°C
- Winter: Down to −20°C (depends on climate class)
- Aromatics: Max 11%
- Polycyclic aromatics: Max 2%
- Lubricity (HFRR @60°C): Max 460 μm
3. Applications:
- Passenger vehicles with diesel engines
- Commercial trucks, buses
- Generators and modern industrial equipment
- Marine engines (in emission-controlled areas)
4. Environmental & Regulatory Compliance:
- Meets Euro 5 standard, limiting NOx, PM, and HC emissions
- Required for vehicles with Diesel Particulate Filters (DPF) and Selective Catalytic Reduction (SCR) systems
- Compatible with Euro 5 and Euro 6 engines
5. Market & Trade: - Standard diesel fuel in Europe, Gulf states, Singapore, South Korea, and increasingly in Africa and Asia
- Commonly exported under EN590:2009 or EN590:2013 specs
- Delivered by truck, vessel, or rail
- Requires SGS or equivalent inspection
