Definitions

  • the subject of this invention is the method of starting and operation of diesel engines fed with slow-burning fuel, applied especially for plant and mineral fuels with a high level of salt and other admixture pollution.
  • pre-ignition plugs are used for easier starting. Their task consists in heating the combustion chamber up, so as to facilitate the ignition of fuel particles which are in a phase of proper mixture preparation. This situation, for example, occurs in diesel engines operating with a precombustion or swirl chamber. In these engines, pre-ignition plugs are placed, whenever possible, on the periphery of the combustion chamber so as not to disturb the process of creation of the fuel mixture, which is obtained by swirling.
  • a diesel engine which is suitable for operating with slow-burning fuel is known from the German brief of protection right for utility pattern No. 295 15 245.1.
  • a pre-ignition plug that reaches deeply into the combustion chamber, i.e. into the precombustion chamber, swirl chamber or chamber of direct-injection engine is employed.
  • the plug should be placed so that the injected jet exactly or partly hits the plug and is prepared there.
  • the purpose of this invention is to create a method of starting and operation for diesel engines fed with slow-burning fuel because traditional methods and systems of starting and operation of diesel engines do not have any, have slender, or have very little possibility of starting or operating in optimum service conditions with the use of viscous and non-flammable fuels, especially at low ambient temperatures.
  • the traditional systems of fuel mixture creation are not, for construction reasons, able or are only in very limited scope able to prepare these fuels for engine starting. The reason for this lies primarily in excessive fuel viscosity. Because of this, the temperature generated in common diesel engine designs which arises from compression and also the calorific effect of available glow elements are insufficient or barely sufficient to consistently ignite slow-burning fuels, especially those with a high temperature of ignition. Also, currently employed filters in engine circulating lubrication system are insufficient to ensure the long-term and stable engine operation, without worrying about its technical condition.
  • the method of starting and operation of diesel engines fed with slow- burning fuels in accordance with this invention is characterized by the fact that fuel supplied to the combustion chamber is heated up in pipes or facilities delivering it to the engine, or in a heat-exchanger which is situated in front of the fuel intake to the combustion chamber, the fuel is additionally heated up by a glow facility which is situated in the combustion chamber until the fuel is precisely sprayed, advantageously, into a fuel and air mixture form, or most advantageously, to a form when the mixture contains fuel in a gaseous state and air, or to a mixture similar to this form and, at the same time, oil that is found in the engine circulating lubrication system is subjected to filtration to the level of at least 1 ⁇ m, or better.
  • the advantage of the method in accordance with this invention is the possibility of feeding the engine with plant and mineral oils containing impurities, for example, salts. These fuels, after reaching the hot surfaces, do not cause any damages or harm and at properly selected parameters, fuel changes its state in the hot zone directly in front of the surface material, up to the ideal situation which is characterized by full conversion into a gaseous state.
  • Example. The method of starting and operation of diesel engines fed with slow-burning fuels which employ glow facilities reaching deeply into the combustion chamber consists in that the fuel delivered to the combustion chamber is heated up in pipes which deliver it to the engine and, additionally, is heated up by a glow facility which is situated in the combustion chamber, until its viscosity decreases to a sufficiently low level when it is possible to obtain a gaseous state of the fuel, upon which it is mixed with air and, in the same time, oil that is found in the engine circulating lubrication system is subjected to a filtration to the level of 1 ⁇ m and the process of heating fuel in fuel pipes before its delivery to the engine is realized by an electric resistance system.

Abstract

L'invention concerne un procédé permettant de faire démarrer et fonctionner des moteurs diesels alimentés par un carburant à combustion lente, qui s'applique notamment aux carburants d'origine végétale et minérale pollués à un degré élevé par des sels et autres additifs. Selon le procédé, le carburant fourni à la chambre de combustion est chauffé dans des tuyaux qui l'amènent au moteur, ainsi que par un dispositif de combustion lente situé dans la chambre de combustion, jusqu'à ce qu'il soit vaporisé avec précision de façon à se présenter sous une forme où le mélange contient du carburant à l'état gazeux et de l'air; en même temps, l'huile qui se trouve dans le système de lubrification du moteur est soumise à une filtration jusqu'à un niveau d'au moins 1 νm ou davantage.
