I'm an expert in the field of automotive engineering, and I'm here to provide you with a detailed explanation regarding the flammability and fire risk associated with diesel engines.
Diesel engines, like any internal combustion engine, are designed to operate under controlled conditions to ensure safety and efficiency. The fuel used in diesel engines is diesel fuel, which is a hydrocarbon-based liquid that is indeed flammable. The flash point of diesel fuel is a critical parameter that determines the temperature at which the fuel can vaporize to form an ignitable mixture in the presence of an ignition source. For diesel fuel, this flash point ranges between 52 and 96 degrees Celsius. This means that under normal atmospheric conditions, diesel fuel will not ignite until it reaches these temperatures.
However, it's important to note that the ignition temperature of diesel fuel is higher than its flash point, typically around 210 to 250 degrees Celsius. This is the temperature at which diesel fuel will spontaneously ignite without an external ignition source. Therefore, for a diesel engine to catch fire, two conditions must be met: the diesel fuel must be heated to its flash point to form a flammable mixture, and then it must be exposed to an ignition source, such as a spark or a hot surface, that can raise the temperature to its ignition point.
The statement that diesel fuel is flammable and has a slower flash point than gasoline is accurate. Gasoline has a lower flash point and is more volatile, which means it can ignite more quickly and easily than diesel. This is why gasoline engines can be more prone to fires in the event of an accident or a malfunction. However, this does not mean that diesel engines are immune to fire risks. They can still catch fire under the right conditions, such as in the event of a severe accident where the fuel tank is ruptured and the fuel comes into contact with a hot surface or ignition source.
It is also worth mentioning that diesel engines are equipped with various safety features to minimize the risk of fire. These include fuel shut-off valves that can be activated in the event of an accident to prevent fuel from leaking out, and fire-resistant materials in the engine compartment to contain any potential fire.
In summary, while diesel engines are designed to be safe and reliable, they can indeed catch fire under certain conditions. The key factors that contribute to this risk include the flammability of diesel fuel, its flash point, and the presence of an ignition source. However, with proper maintenance, adherence to safety protocols, and the use of safety features, the risk of fire in diesel engines can be significantly reduced.

Diesel fuel has a flash point between 52 and 96 degrees C. So, yes, diesel fuel can catch fire and therefore, under the right conditions, Diesel engines can catch fire, too. ... It is flammable, it has a slower flash point than gas so it starts slow like kerosene.
