As an expert in the field of energy and fuels, I've spent considerable time studying the properties of various fuels, including diesel. Diesel, a versatile and widely used fuel, is known for its high energy density and efficiency, especially in heavy-duty engines and transportation systems. The calorific value, also known as the heating value, of a fuel is a critical parameter that indicates the amount of energy released when the fuel is completely combusted.
The calorific value of diesel fuel is indeed a topic of interest for many, particularly those involved in energy production, distribution, and consumption. It's important to note that the calorific value can vary slightly depending on the specific formulation of the diesel and the conditions of measurement. However, as a general approximation, the calorific value of diesel is around 45.5 MJ/kg. This value is slightly lower than that of gasoline, which is approximately 45.8 MJ/kg.
Despite this slight difference, diesel has a distinct advantage over gasoline in terms of energy content by volume. Diesel is denser than gasoline, which means that for the same volume, diesel contains more energy. This is why, when comparing the energy content per liter, diesel comes out ahead. The energy content of diesel by volume is roughly 36.9 MJ/liter, compared to 33.7 MJ/liter for gasoline. This difference is significant, especially in applications where fuel efficiency is a key factor.
The higher energy content of diesel by volume is one of the reasons why it is preferred for heavy-duty vehicles and machinery, such as trucks, buses, and construction equipment. These vehicles require a large amount of energy to operate efficiently, and diesel provides that energy in a compact form.
Moreover, the efficiency of diesel engines is also a contributing factor to the preference for diesel fuel. Diesel engines typically have a higher thermal efficiency compared to gasoline engines, which means they convert a greater proportion of the fuel's energy into mechanical work. This results in better fuel economy and lower operating costs, which are important considerations for fleet operators and businesses.
In summary, while the calorific value of diesel is slightly lower than that of gasoline on a per-kilogram basis, its higher density and energy content per liter make it a preferred choice for many applications. The efficiency of diesel engines further enhances the appeal of diesel fuel in the transportation and heavy machinery sectors.

The calorific value of diesel fuel is roughly 45.5 MJ/kg (megajoules per kilogram), slightly lower than petrol which is 45.8 MJ/kg. However, diesel fuel is denser than petrol and contains about 15% more energy by volume (roughly 36.9 MJ/litre compared to 33.7 MJ/litre).Sep 24, 2016
