In addition to the usual air intake or intakes of the carburettor, we provide an adjustable additional air intake, diagrammatically shown at 7, permitting the variation at will of the quantity of air, admitted to the mixture according to the tel'nperature and the hygrometric state ofthe'air and to the quality of the fuel employed. When the engine is hot, A and the external temperature favorable, a supplementary air admission is vefl'ected through intake '5, this additional air, upon its aassage through the apertures in the plates, mixing intimately with the first mixture suprealizing an economy in fuel. 7

In the embodiment shown in Fig. 3, rods 8 carrying substantially ovoid elements 9 are provided, these rods extending along the center lines of the apertures, and one element 9 being provided in each aperture.

The rods 8 are solidary joined, forexample by a plate 10, and connectedby a linked rodvll to any suitable controlling device. Said device may be realized, as shown in Fig. 3, by an operativefconnection with the throttle valve 2 of the carburetor in-such a manner that the elements 9 will partly obturate the apertures G when the engine is running under light load conditions. A safety device may be further provided for locking the rods 8 in aposition in which the elements 9 completely obturate the apertures 6 thereby preventing the operation of the engine and consequently thetheft of the automobile, for example, of which the engine forms the power unit. Said locking device may be realized as shown, Fig. 3, by a small plate 12 which slides in the body 4 and maintainsthe plate 10 in the position 10 The plate 12 isactuated by a bent lever 13 and a rod 14; said latter can be locked by any suitable bolt or padlocln Claims r '1'.
