VAPORIZER FOR INTERNAL-COMBUSTION MOTORS.
Specification of Letters Patent.
Patented June 30, 1908.
I Application filed August 15, 1907. Serial No. 388,661.
To all whom it may concern:
Be it known that I, Fnrnnnren OBER- niiNsLI, a citizen of Switzerland, residing at Kesswil-on-the-Bodensee, in the Republic of Switzerland, have invented certain new and useful Improvements in and Relating to Improvements in Vaporizers for Internal-Combustion Motors, of which the following is a specification.
The invention has reference to vaporizers for internal combustion motors, for liquid fuel, in which the fuel is converted into a gaseous condition by means of a vaporizer placed before the cylinder head, and the invention relates more particularly to the employment of a high compression for the air of combustion, in order to obtain as complete a combustion as possible. In machines of this kind as hitherto constructed, premature ignitions frequently take place when the air at high pressure passes into the heated vapo-v rizer, and various means, such as water sprays are adopted for preventing such premature ignition. All these methods present numerous defects and are not always reliable, so that frequently the object sought is not attained.
In the internal combustion motor, an obturating member is arranged in the known manner in the passage connecting the vaporizer with the cylinder head, and in accordance with the present invention this member is slowly closed during the suction of the air so that at the beginning of the-compression period the combustion chamber is divided into two compartments entirely separate one from the other. In one of the compartments, in the cylinder, there is practically only pure air, as only a very small quantity of fuel in a finely divided condition is contained therein, that is vto say the small quantity which reachedthe cylinder during the .short time during which the obturating member in the passage connecting the vaporizer and the cylinder was open. In the second compartmerit, in the vaporizer, only fuel is present which has been vaporized.
, munication At the end ofthe compression period, comcylinder is established by opening the obturating member arranged on the connecting assage, whereupon the combustion of the ot fuel takes place almost instantly that is as soon as it is subjected to theinfluence of the high pressure air. 1
In order to' hastenthe' combustion by in between the vaporizer and the.
timately mixing the fuel with the air, before the vaporizer is placed in communication with the cylinder a portion of the high pressure air is admitted to the vaporizer, and eXpels the fuel from the vaporizer towards the cylinder head, at the proper time an intimate mixing of the fuel with the air contained in the cylinder being produced.
The object of the invention is illustrated by way of example in the accompanying drawing, in which:
Figure 1 represents a longitudinal section through the cylinder head on the line AA of Fig. 3-. Fig. 2 represents a longitudinal section on tho lineB-B of Fig. 3. Fig. 3 is a view'of thecylinder head and Fig. 4 represents a section on the line O-C of Fig. 3.
The engine, which a whole follows the known construction, comprises the air admission valve a and the exhaust valve 1) in the cylinder head, which latter carries the vaporizer (Z communicating with the cylinder through a relatively narrow passage 0. The nozzle (2 supplying the combustible and a valvef are arranged in the vaporizer wall;
this'valve obturates a passage g. in the direction of the vaporizer. A rotary valve h or other appropriate obturating member is inserted in the narrow passage 0 connecting the vaporizer with the cylinder. The rotary valve presents two passages, a large passage, i corresponding to the passage 0 and a passage j of smallercross section. This latter passage corresponds to a passage 76 formed in the cylinder head and leading into a passage 1 running perpendicularly to the axis of the rotary valve (Fig. 4) and which communicates with the passage 9 leading to the vaporizer d by means of a pipe m. The passages i, are arranged relatively one to t 1e other in such a manner that after the obturation oi the connecting passage 0 between the vaporizer and the cylinder a slight rotation in the same direction is necessary in order to set the rotary valve in such a manner that the passage 7' comes opposite the passage is.
The vaporizer d is surrounded by a cooling acket 0 closed by means of a cover '1) and receiving cooling liquid in order to prevent eX- eessive heating of the vaporizer. The covers 7) also serve to give access to the vaporizer I for heating the same before the engine is started.
The 0 eration of my device is as follows At the eginning of the suction period, the
rotary valve h is adjusted in such a manner that the vaporizer and bustion of the cylinder are connected one With the other; During the suction, fuel is forced to the vaporizer by anysuitable means, for example a pump, through the nozzle,e' and air-enters the cylinder.
air is alone compressed, so that the pressure of permlssible compression is very 1gb, as
premature ignitions are impossible owing to the closing of the vaporizer. Before the end of the compression period the rotary valve is turned by meansof the rod W, joined to any suitable reci rocating part of the'engine (not shown) unt1 its bore 1', registers with the I v passage 7c, (see Fig. 4) while the passage 0,
v with the passage and thelatter connects with the vaporizer d, through the passage g,
, flowsthrought the vaporizer before .the end of .the pressure in sai the va orizerandthe cylinder his passage is, connects Z, and ipe m, as shown,
connectin I remains c osed.
and valve f, as best. seenin Fig.2, all as above disclosed. The said passages is, Z and m, being restricted, a part of the com ressed air from the cylinderli e same and the valve f, into the compression. period; where it expands, mixes with the fuel in the .va
1 f 11 h vaporizer. ate o owin t e o e'ning' the valve h, is so rotalted-as open direct communication through the latvaporizer and said cylinder. This communication is estab hed 'at,.or an instant before, the 'end of the compression period,.and air, therefore, at a h pressure flows 'fromthe cyhnder into tie vaporizer in opposition to the mixtureof air and fuelwhich was formed in the vaporizer-at and" forces a portion of out of said vaporizer and into ,said cylinder, thereby causing both cylinder and vaporizer to be filled with air and fuel, and an almost Air at h r'essure remainsin the i .m' after its d di ine dtion with the p pe the ressure beneath the valve f becomes sm er than the ressure of the air in the pipe m. This is t 6 case' at theendof the expansion,- and during, the-exhaust. Thethen passes and-in whatmanner the I formed, I declare that What-I claim is:
and means said passa es near orizer d, and increases Immedi-f ofthe passage is, to close said pasr sage and to open the passage c, andthereby I ter between the'said .vided with an air inlet val chamber provided with a instantaneous com- 1 vaporizer until from the pipefin -in to the vaporizer and flushes thislatter, as the eomustion residues are forced into the cylinder,
thereby preventing fouling of the vaporizer in an effective manner. v I
