Diesel-powered cars account for 75% of global car demand. The diesel engine offers greater torque and lower consumption.
If we look at some data from the last years of automotive mechanics industry, we realize that the most commercially successful cars are coming equipped with diesel engine, which devastate in sales to gasoline engines.
However, the story was not always like this. Until recently, in the early 1990s, the world demand for cars with such motorization hardly exceeded 10%, while in 2010 the situation reverses, reaching 75%.
But what features offered by the diesel engine that have catapulted him to the pinnacle of commercial success?
To begin, we say that the diesel engine delivers more torque and better performance of consumption, which makes it more efficient. On the other hand, over the years it has become quieter and cleaner in terms of C02 emissions. In addition, it can now develop a competitive power, so there are sports cars and high-end equipped with this engine.
This superiority in motorized force (torque) of the diesel engine lies in the violence of your internal air-fuel which, unlike the gasoline engine burns when subjected to enormous pressures mixture explosions, so no need of a spark plug that ignites a spark for its inflammation.
To better understand this process, we briefly summarize what is happening within its mechanics:
In the diesel engine, the air is contained within the combustion chamber of the cylinder, where it is compressed to the end of generating high temperatures. At that time, the fuel is introduced in a pulverized form by an injector into the chamber, where it spontaneously explodes, which generates a pressure that pushes the piston of the cylinder downwards, causing the connecting rod to transmit this movement to the crankshaft, which Spins, transforming this force into mechanical work.
Then, in order to ensure the continuity of the engine force, the combustion gases are extracted and a new mixture of air and then fuel is supplied cyclically.
