  " Dispositif mélangeur pour moteurs Diesel actionnés selon le procède à deux combustibles, et en particulier au gaz de gazogène ", 
On fait fonctionner les moteurs Diesel selon le procédé ait à deux combustibles de façon telle que le démarrage et la marche à vide au moteur sont réalisés à l'aide de l'ad-   duction   d'huile Diesel, cependant que jusqu'à la pleine charge une proportion ou fraction de plus en plus grande du deuxième combustible est ajoutée à la fraction, restant      constante, d'huile Diesel.

   Dans les installations de ce type connues jusqu'ici, il se produisait fréquement des diffi-   'cultes,   surtout   @   lors du passage de la marche ou fonctionnement en Diesel pur aux marches au mélange, car l'adduction d'air pour la marche en Diesel, d'une part, et pour la marche au gaz, d'autre part, ne pouvait pas être adaptée d'une façon suffisamment soigneuse aux différents besoins. Des difficultés de dosage de ce genre se présen- taient en particulier pour les moteurs Diesel actionnés 

 <Desc/Clms Page number 2> 

   additionnellement   avec du gaz de gazogène selon le procédé à deux combustibles. 



   L'invention concerne un dispositif mélangeur pour moteurs Diesel actionnés selon le procédé à deux combusti- bles, et en particulier avec du gaz de gazogène, et consiste essentiellement, en vue de   l'élimination   des inconvénients décrits, en ce que pour la marche en Diesel, il est prévu une adduction d'air particulière, séparée de celle destinée à la marche au gazogène. vec un dispositif de ce genre, il ne se produit plus aucune difficultés de dosage lors du passage d'un des différents modes de fonctionnement à un autre, car il est possible d'opérer avec la précision néces- saire l'adduction d'air pour la marche en Diesel et d'utili- ser un dispositif melangeur usuel pour l'adduction du mélange pour la marche au gazogène. 



   Selon l'invention, on opère, avec un avantage particu- lier, l'adduction d'air pour la marche en Diesel par une ouverture ou tuyère calibrée qui est utilement montée de façon qu'elle puisse être remplacée. 



   D'autres particularités   avantageuses   de l'invention ressortent du dessin sur lequel l'invention est mise en lumière par un exemple de réalisation : / 
La figure 1   represente   un dispositif   melangeur   selon l'invention   penaant   la période d'allumage ou d'attisage du gazogène; la figure 2, pendant la marche à vide; et la fi- gure 3, en pleine charge. 1, désigne la conduite venant   du   gazogène, et   2,   la conduite menant au moteur Diesel. La tu- bulure 3 forme le raccord au dispositif d'attisage, qui est par exemple un   injecteur   actionné par les gaz d'échappement, et la tubulure 4 est une tubulure à air.

   Le clapet ou papil- lon de mélange 5 est monté dans la tubulure   2;-le   papillon d'attisage 6, dans la tubulure 3; et le papillon à air, dans la tubulure 4. En outre, le papillon   d'étranglement 8   est 

 <Desc/Clms Page number 3> 

 encore monté dans la partie de conduite située entre les   @   tubulures 1 et 2.

   Pour la marche en Diesel, il est prévu une.conduite d'adduction d'air spéciale 10,   raccoraée   au filtre à air 9, dont le débit est   deternine   par la tuyère ou ajutage calibré 11 et qui   debouche   derrière le papillon 5 dans la tubulure   2.   La tuyère 11 est, comme cela est visible sur le dessin, réalisée de façon qu'elle puisse être   rempla-   cée par une autre, de sorte que la quantité d'air fournie peut être adaptée, pour une même construction du mélangeur, au   ronctionnement   en marche à vide de chaque moteur Diesel particulier à commuter sur la marche au gazogène. Le fonc- tionnement du dispositif representé est le suivant. 



   Pendant la période d'allumage ou d'attisage du gazogène, les papillons 5,   7, 8   sont fermés et le papillon 6 est ouvert, comme sur la figure 1. Le moteur Diesel est actionné en Diesel pur et est alimente en air par la conduite 10. Le gazogène est mis en marche par le dispositif   d'attisage   qui est raccordé à la tubulure 3 et qui aspire le gaz à travers la zone d'incandescence du gazogène. 



   Pendant la période de marche à vide selon la figure   2,   les papillons d'étranglement 5, 7 restent fermés et le moteur fonctionne comme avant en Diesel pur. Le papillon d'étrangle- ment 8 est complètement ouvert et le papillon d'étranglement 6 est fermé. Toutefois, il est possible aussi de laisser   dans   ce cas le papillon   d'étrangement   6 encore dans la position d'ouverture, afin de maintenir le gazogène en feu par l'ac- tîon du dispositif d'attisage. 



   Dans la période de pleine charge selon la figure 3, le papillon 6 est fermé   complètement;   le papillon   d'étranglement   8 est ouvert, de même que ies papillons 5 et 7, qui sont utilement réunis par un accouplement à entraînement. Le moteur Diesel reçoit par la conduite 10 la quantité d'air usuelle nécessaire à son fonctionnement à vide et, additionnellement, 

 <Desc/Clms Page number 4> 

 le mélange de gaz et d'air venant du gazogène et formé dans le mélangeur. L'adduction d'air pour le fonctionnement en Diesel reste toutefois complètement indépendante de la   l'or-

 jgmation du mélange et de l'adduction d1aielci. 



   La représentation graphique indique certes une   dispo-   sition particulièrement avantageuse, peu encombrante et précisément appropriée tout particulièrement à la propulsion des véhicules. Toutefois, l'invention   n'est   pas limitée à l'exemple de réalisation représente. Les propositions sur lesquelles elle est fondée peuvent au contraire être encore réalisées de n'importe quelle autre manière au point de vue de la construction.

  "Mixing device for diesel engines operated according to the two-fuel method, and in particular gasifier gas",
Diesel engines are operated according to the dual fuel method such that starting and idling of the engine is carried out with the aid of the diesel oil addition, while until full. charge an increasing proportion or fraction of the second fuel is added to the fraction, remaining constant, of diesel oil.

   In installations of this type known hitherto, difficulties frequently arose, especially when switching from pure diesel operation or operation to mixed steps, since the air supply for operation in Diesel, on the one hand, and for gas operation, on the other hand, could not be adapted in a sufficiently careful manner to the various needs. Dosing difficulties of this kind arose in particular for diesel engines operated.

 <Desc / Clms Page number 2>

   additionally with gas generator gas according to the two-fuel process.



   The invention relates to a mixing device for diesel engines operated by the two-fuel process, and in particular with gasifier gas, and consists essentially, with a view to eliminating the drawbacks described, in that for running in Diesel, a special air supply is provided, separate from that intended for operation with gasifier. With a device of this kind, there are no longer any dosing difficulties when switching from one of the different operating modes to another, since it is possible to operate the air supply with the necessary precision. for diesel operation and to use a conventional mixing device for the adduction of the mixture for gasifier operation.



   According to the invention, one operates, with a particular advantage, the air supply for diesel operation through a calibrated opening or nozzle which is usefully mounted so that it can be replaced.



   Other advantageous features of the invention emerge from the drawing in which the invention is highlighted by an exemplary embodiment: /
FIG. 1 represents a mixing device according to the invention controlling the period of ignition or stirring of the gasifier; FIG. 2, during idling; and Figure 3, fully loaded. 1, designates the pipe coming from the gasifier, and 2, the pipe leading to the diesel engine. The tube 3 forms the connection to the fan device, which is for example an injector actuated by the exhaust gases, and the tube 4 is an air tube.

   The mixing valve or butterfly 5 is mounted in the pipe 2; the scouring butterfly 6 in the pipe 3; and the air throttle, in the pipe 4. In addition, the throttle valve 8 is

 <Desc / Clms Page number 3>

 still mounted in the pipe part located between the @ pipes 1 and 2.

   For diesel operation, a special air supply pipe 10 is provided, connected to the air filter 9, the flow rate of which is determined by the nozzle or calibrated nozzle 11 and which opens behind the butterfly valve 5 in the pipe 2. The nozzle 11 is, as can be seen in the drawing, made so that it can be replaced by another, so that the quantity of air supplied can be adapted, for the same construction of the mixer, to idle operation of each particular diesel engine to be switched to gasifier operation. The operation of the device shown is as follows.



   During the period of ignition or fanning of the gasifier, the butterflies 5, 7, 8 are closed and the butterfly valve 6 is open, as in figure 1. The Diesel engine is powered by pure Diesel and is supplied with air by the gasifier. pipe 10. The gasifier is started by the fan device which is connected to the pipe 3 and which sucks the gas through the zone of incandescence of the gasifier.



   During the idling period according to figure 2, the throttle butterflies 5, 7 remain closed and the engine operates as before in pure diesel. The throttle butterfly 8 is fully open and the throttle butterfly 6 is closed. However, it is also possible in this case to leave the throttle valve 6 still in the open position, in order to keep the gasifier on fire by the action of the scouring device.



   In the full load period according to figure 3, the throttle 6 is completely closed; the throttle butterfly 8 is open, as are the butterflies 5 and 7, which are usefully joined by a drive coupling. The diesel engine receives through line 10 the usual quantity of air necessary for its operation when empty and, additionally,

 <Desc / Clms Page number 4>

 the mixture of gas and air coming from the gasifier and formed in the mixer. The air supply for diesel operation remains, however, completely independent of the or-
 EMI4.1
 jgmation of the mixture and the adduction d1elci.



   The graphical representation certainly indicates a particularly advantageous arrangement, which takes up little space and is precisely suitable, in particular, for the propulsion of vehicles. However, the invention is not limited to the exemplary embodiment shown. The propositions on which it is based, on the contrary, can still be realized in any other way from the point of view of construction.
