Abstract

The charge control for an i.c. engine inlet has a grid formed of parallel vanes which are inclined at a large angle w.r.t. the flow axis. The grid occupies most of the width of the intake and can have a second grid downstream in which the vanes are inclined at a reverse angle. - The two grids can be connected by a single grill, with the vanes shaped to divert the charge at least twice. The deflectors can be mounted on a sleeve fitted between the intake manifold and carburettor.

Description

       

  Madame Marcelle JACQUET,épouse- HERBAUX.

INVENTION.

  
 <EMI ID=1.1>

 <EMI ID=2.1> 

  
sence et de gouttelettes dont les plus grosses n'ont pas le temps de brûler pendant 1[deg.]explosion.Il en résulte un gaspillage de carburant pouvant atteindre 25%.

  
Les artifices utilisés pour éviter ces pertes:hélices,tamis,c8nes percés,gicleurs spéciaux,réchauffeurs divers,ont

  
 <EMI ID=3.1> 

  
réchauffé.

  
Ce problème, a été résolu en chauffant seulement les gouttelettes et non l'air les contenant.Une ou plusieurs persien-

  
 <EMI ID=4.1> 

  
se entre les volets fixes(5-8) des persiennes:Les gouttelettes(l-2),à cause de leur masse,sont peu déviées et percutent les volets chauds..

  
Il y a,pour plus d'efficacité,au moins deux persiennes parai lèles(Fig D),ou en opposition(Fig A),plus performant.

  
Dans ce cas,on peut fusionner les volets qui' ont vaguement la forme d'aube de turbine,la ressemblance s'arrêtant là. Etant donné leur vitesse,les gouttelettes capturées s'étalent sur les volets très inclinés à cet effet.Le carburant s'évapore donc très vite,sa vapeur étant emportée au fur et à mesure par l'air,auquel elle se mélange.

  
Le dispositif en persienne perpendiculaire au conduit d'air

  
a ses volets très courts,ce qui facilite le passage de la chaleur de la bride support(K) jusqu'au centre(O) des volets. De plus,il s'oppose à la rotation du flux gazeux,contraire- , ment à la plupart des dispositifs qui font le contraire,et limite ainsi les pertes de charge,tout en évitant la centrifugation du carburant plus dense vers l'extérieur,source d'hétérogénéité-

INVENTION.

  
 <EMI ID = 1.1>

  
dull, especially those of vehicles, whose highly variable power is supplied by carburetors.

  
 <EMI ID = 2.1>

  
gasoline and droplets, the largest of which do not have time to burn during 1 [deg.] explosion. This results in wasted fuel of up to 25%.

  
The devices used to avoid these losses: propellers, sieves, drilled cones, special nozzles, various heaters, have

  
 <EMI ID = 3.1>

  
warmed up.

  
This problem was solved by heating only the droplets and not the air containing them.

  
 <EMI ID = 4.1>

  
between the fixed shutters (5-8) of the shutters: The droplets (l-2), because of their mass, are little deviated and strike the hot shutters.

  
For more efficiency, there are at least two parallel louvers (Fig D), or in opposition (Fig A), more efficient.

  
In this case, it is possible to merge the flaps which have the vaguely shape of a turbine blade, the resemblance ending there. Given their speed, the captured droplets spread over the flaps which are very inclined for this purpose. The fuel therefore evaporates very quickly, its vapor being carried away progressively by the air, with which it mixes.

  
The device louver perpendicular to the air duct

  
has its very short flaps, which facilitates the passage of heat from the support flange (K) to the center (O) of the flaps. In addition, it opposes the rotation of the gas flow, contrary to most devices which do the opposite, and thus limits the pressure drops, while avoiding the centrifugation of the denser fuel towards the outside, source of heterogeneity-
