The specific gravity of good diesel fuel, measured at 60/60°F, falls between 0.82 and 0.88. This range also applies to its density when measured at 15.6°C.
Understanding Diesel Fuel Specific Gravity
Specific gravity is a crucial characteristic of diesel fuel, indicating its density relative to water. This property is vital for several reasons, including:- Energy Content: Denser fuels (higher specific gravity) generally contain more energy per unit volume, which can impact fuel economy and engine performance.
- Combustion Quality: The specific gravity range ensures optimal fuel atomization and combustion within the engine, leading to efficient power generation and reduced emissions.
- Fuel Blending and Quality Control: Maintaining specific gravity within the specified range is essential for consistent fuel quality and performance across different batches and blends. As detailed in fuel refining and chemistry, properties like density and API gravity are closely monitored during fuel production to meet industry standards.
Key Values for Good Diesel Fuel
The following table summarizes the typical specific gravity and density values for good diesel fuel based on standard measurements:| Property | Value Range | Measurement Conditions |
|---|---|---|
| Specific Gravity | 0.82 to 0.88 | 60/60°F |
| Density | 0.82 to 0.88 | 15.6°C |
Note: The reference clarifies that the specific gravity at 60/60°F and the density at 15.6°C share the same numerical range, indicating their close relation and use in fuel specifications. For a comprehensive understanding of fuel blending, density, and API gravity, further details can be found in specialized resources on diesel fuel refining and chemistry, such as Chapter 4 of relevant industry guides.
