The diesel engine is a type of internal combustion engine developed between 1893 and 1897 by a
German engineer who gave his name to the invention: Rudolf Diesel.
Invented in 1897 by Rudolf Diesel
Principle and operation of diesel engine
oil, diesel or, rarer, vegetable oils. Unlike a petrol engine, the diesel engine does not have spark plugs,
since the spark plug is spontaneous thanks to the phenomenon of auto-ignition.
The basic principle is based on the presence of pistons which slide inside cylinders connected to
intake and exhaust manifolds. The operation of the diesel engine is divided into four stages: the air
intake allowed by the descent of the piston, the compression of the air then produced by the reverse
movement, injection, combustion and expansion and then exhaust gas Burned. This cycle of
operation is the most used for motor vehicles equipped with this type of engine. There are, however,
two-stroke diesel engine cycles, used by ships.
Évolution et utilisation du moteur diesel
The diesel engine has seen a number of improvements over the years, such as turbocharger turbocharging, which allowed performance to increase after the 1980 s. Thanks to this innovation, it has had a better performance than its competitor ", The gasoline engine.
