INTERNAL COMBUSTION ENGINE FEDWITH HEAVY FUELS Dec. 2 2, 1936.

Patented Dec. 22, 1936 PATENT OFFICE INTERNAL COMBUSTION ENGINE FED wrrn HEAVY FUELS Albert Bagnulo, Courbevoie, France Application February 13, 1933, Serial No. 656,602
In France March 2, 1932 i 4 Claims.
In engines adapted to be fed with heavy fuels particularly, and more generally with liquid fuels, the independence between the injecting and the suction device contributes to make the engine more complicated and to provoke irregularities in the carburetion process.
The present invention relates to improvements in such engines, according to which the mixture in suitable proportions and the vaporization of the fuel are effected preliminarily under the sole effect of the pressure lowering caused by the piston during its suction stroke.
The features of the invention which I believe to be patentable are pointed out with particularity in the appended claims. The invention itself, however, together with further objects and advantages thereof, will be best understood by reference to the following description taken in connection with the accompanying drawing which shows by way of example in section, an embodiment of an engine according to the invention.
In this engine, the fuel is sucked, not directly into the cylinder C, but into an additional combustion chamber A.
The main volume of fresh and pure air is sucked directly into the cylinder through valve S or any such known and usual means.
The reason of such disposition is to avoid the passing through the cylinder of any fuel before its burning.
B is an additional valve opening into combustion chamber A. The additional air and fuel are sucked respectively through the chamber 0 and the spraying nozzle G, the nozzle G being fed from the constant level tank Q. However, the air and fuel proportion flowing through 3 will, in any case, form a mixture too abundant in liquid particles for igniting.
Between spraying nozzle G and valve B is located a butterfly valve D. This butterfly valve D is controlled by the usual means and serves to vary the quantity of the rich mixture applied to the engine during each suction stroke. It may be of any suitable shape. The said butterfly valve may be omitted and its working replaced by a suitable variation of the lift of valve B, such action being obtained, forlnstance, by means of an eccentric drive controlling the tumbler R. Of course, any other suitable mechanicalmeans may be used for the same purpose.
Valve B may be automatically actuated and, in such case, the variation in its lift may be obtained by means of an adjustable stop (not shown) located between the base M and the cup N of 55 valve 3.
If it is desired to run the engine with feeding by. means of two or morefuels, simultaneously or not, as for example, spirit and an oil, there may be provided several spraying nozzles in the chamber 0. Fig. 2 represents a section of the cham- 5 ber O, in line with the spraying nozzle G of Fig; 1. This adaptation provides for the feeding of a plurality of fuels, and comprises two identical spraying nozzles, penetrating intothe chamber 0, the fuels entering through the paths 1 and 2.
The device according to the invention may be used to feed either one or several of the cylinders of a given engine.
The present invention is not,'of, course, limited to the particular embodiment above described 15 by way of example; it may accommodate the numerous modifications of which the man of the art is aware, without departing from its general meaning.
