The term diesel comes from Rudolf Diesel, a German engineer born in 1858 and died in 1913 who went down in history for the development of a type of engine and a fuel that bear his surname. The idea of diesel, therefore, can refer to said engine and fuel or to the vehicle that uses them.
Diesel fuel or fuel, also known as gas oil or gas oil, is a product obtained from the distillation and purification of crude oil. This fuel is used in diesel engines, created by the aforementioned German engineer in 1893: these are internal combustion engines in which, due to the high temperature registered by the compressed air in its cylinder, the fuel self- ignites when it is injected into the camera. A diesel vehicle, on the other hand, uses this kind of engine and works with the aforementioned fuel.
The main characteristic of the diesel engine is that the high temperature that derives from the high compression ratio allows the fuel to self-ignite. Compression, therefore, increases the temperature of the combustion chamber: when the fuel (diesel, gas oil or diesel) is injected and mixed with hot air, it self-ignites. Therefore, a spark is not needed, as is the case in gasoline engines. Combustion, in turn, causes the gas in the chamber to expand, displacing the piston outward.
Due to its design, the diesel engine achieves a great thermodynamic efficiency, generally higher than that registered by gasoline engines. Diesel, on the other hand, is usually cheaper than gasoline, making the diesel engine a low-cost engine to operate.
In addition to the already exposed advantages of diesel cars compared to gasoline cars, other equally important ones must be highlighted, such as these:
-The former are considered to be much more efficient because their dragging capacity is much more remarkable.
-In the same way, it should not be overlooked that they consume less fuel per kilometer.
However, they also have a number of disadvantages that should not be forgotten, such as the following:
-Diesel cars are considered to be equipped with engines that are not only heavier but also much noisier than gasoline ones.
-Likewise, it is indicated that the initial price of these aforementioned vehicles is more expensive than that of the others.
-It is also established that diesel cars require maintenance that is more expensive than that of their “rivals”.
-Of course, it should not be overlooked that in the event that a diesel vehicle breaks down, its repair will be much more expensive, economically speaking, than that of a gasoline one.
-In this list of disadvantages we cannot ignore the fact that diesel cars turn out to be more polluting than gasoline cars. Precisely for this reason now, in countries such as Spain, measures are being taken to limit the circulation of the most polluting diesel vehicles in the center of cities. Madrid is a clear example of this measure being carried out using labels for vehicles.
