As an expert in the field of mechanical engineering with a focus on internal combustion engines, I can provide a comprehensive response to your question regarding the potential for a diesel engine to explode.
Firstly, it is important to understand the fundamental differences between diesel and gasoline engines. Diesel engines operate on the principle of compression ignition, where air is compressed to a high temperature, and then diesel fuel is injected into the hot air, causing it to ignite. Gasoline engines, on the other hand, use spark ignition, where a spark plug ignites a mixture of air and gasoline.
The potential for an explosion in a diesel engine is significantly lower than in a gasoline engine due to the nature of the fuel itself. Diesel fuel has a higher flash point and a lower volatility compared to gasoline. This means that diesel fuel is less likely to ignite when exposed to a source of ignition, such as a spark or flame.
However, this does not mean that diesel engines are completely immune to explosions. The reference to the explosive limits of diesel fuel is crucial here. The lower explosive limit (LEL) is the lowest concentration of a flammable gas or vapor in air that can form an explosive mixture. For diesel fuel, the LEL is indeed less than 1%, and the upper explosive limit (UEL) is about 10%. This indicates that if diesel fuel vapors are present in the air at concentrations between these two limits, they can potentially explode when exposed to a source of ignition.
In the context of a diesel engine, the most likely scenario for an explosion would involve the accumulation of diesel fuel vapors in a confined space, such as a storage tank. If such a tank contains diesel vapors and is exposed to a source of ignition, such as a welding arc, an explosion could indeed occur. This is because the vapors can rapidly mix with the air and form an explosive mixture.
It is also worth noting that while the engine itself is less likely to explode due to the nature of diesel fuel, there are still safety risks associated with the operation of diesel engines. These risks include the potential for fuel leaks, which could lead to the accumulation of vapors in the vicinity of the engine. Proper maintenance and adherence to safety protocols are essential to minimize these risks.
In summary, while diesel engines are less prone to explosions due to the characteristics of diesel fuel, it is still possible for an explosion to occur under certain conditions. The key factors include the concentration of diesel fuel vapors in the air and the presence of an ignition source. By understanding these factors and taking appropriate safety measures, the risk of explosions can be significantly reduced.

The lower explosive limit is less than 1%, and the upper explosive limit is about 10%. That means that diesel fuel vapors from a storage tank can explode with as little as 1% of the air being diesel fuel vapors. ... If the tank contains diesel vapors, a welding arc can easily cause an explosion.Mar 11, 2013
