The diesel-engine is preferably used when there is a need for high torque and good performance: locomotives, boats, trucks, farm tractors, generators, gear auto or public works. From a historical point of view, it is the Navy that is primarily concerned with diesel-engines (Rebuilt Detroit Diesel Series 71). Given the size of first engines, it would seem natural that engineers and naval architects are, before all others interested in this new engine they had instead of hosting.
But it is a Danish merchant ship, Selandia, which was the first in 1912. It is equipped to moderate by other considerations, since it is above all submarines that were fitted. Thus, the French engineer Maxime Laubeuf fitted out its a diesel submarine Egret (1901) for gasoline engines while not developed enough power and steam engines, emitting excessive smoke would have been counterproductive, the concern is precisely to develop a discreet building.
Diesel was preferred because it is less expensive and better spraying with a lower viscosity, but heavy fuel oil, vegetable or mineral oils are sometimes used. In 1924, inventing the injection pump, the French Lucien Eugene Inchauspe (1867-1930) made him a powerful engine. The diesel engine compression ratio has experienced rapid expansion in automobile in Europe from the late 1980s, when the supercharger, turbocharger.
First designed for transport "heavy" (trucks in particular), the diesel-engine eventually earn a spot in individual or family car, even if the engine "essence" remains majority. In fact, diesel having a larger volume calorific value than petrol and enjoying a slightly more favorable taxation, engines are more economical to pump although more expensive to purchase and the maintenance.
For the motor city below (960 mm bore and stroke 2500 mm), the piston moves 5 meters per round. For a rotational speed of 102 r / min, the linear velocity of piston is 8.5 m / s. The rated maximum power output at 92 rev / min, it will be 7.6 m / s. In cylinders of diesel engine operates the fuel combustion, which consists of random access oxidation of by the oxygen present in air.
As soon as the fuel injected (sprayed), it almost instantly ignites, without the need to use a spark ignition. Burning the mixture greatly increases the temperature and pressure in cylinder (60 to 100 bars), pushing the piston providing a force working on a connecting rod, which drives the crankshaft rotation (or crank shaft serving as an axis engine, see crank system).
However, the diesel engine is rarely used on motorcycles and airplanes, including a question-board mass, except that Clerget aircraft were distinguished by a power to weight ratio comparable to that of a gasoline engine, but World War II stopped the development. However, the use of diesel engines in light aircraft, appeared in 1980s began to develop: Cessna L19 equipped with a diesel engine of Renault 25 pushed to 135 hp in 1988, amateur-built aircraft with a Dieselis Isuzu (Opel) 70 hp 19987.
The reasons for the success of diesel engine in car, beyond tax benefits depend on political and not technical choices are mainly due to its higher than the gasoline engine efficiency. This performance can further enhanced by the implementation of innovative technologies: Supercharging utilizes a compressor to increase the amount of air (and thus oxygen) introduced into engine, which is particularly appreciable in elevation (and hence in aviation).
