ART OF CONTROLLING COMBUSTION" IN INTERNAL-COMBUSTION ENGINES.
Application fi led December 80, 1922. Serial No. 608,913.
This invention relates to internal combustion engines and will be fullyunderstood from, the following description, ref-..
erence being had also to the drawing, in which Fig. 1 represents a central sectional view of one .form of apparatus contemplated in the invention;
Fig. 2 is a sectional detail on an enlarged scale, showing the position of parts when the1 engine is under certain load conditions; an p Fig. 3 is a sectional detail of a modification.
Refcrrin more articularly to the drawing, the re erence c aracter 1 designates the air intake leading to a carbureter C of any desired form, the usual choker valve 3 and throttle valve 3' being provided. Extending into the air passage is a tube 4 carrying a, wick 5 which projects above into a perforated wick-cage 6 and below into a liquid container 7.- Advantageously this container accompanying is attached to the tube 4 by a screw thread joint or the like, so as to be readily detachable, it being contemplated that such a container willsupply in convenient manner a chemical agent efiicient in modifying the combustion of hydrocarbon fuels to the end of checking knocking or detonation. Slidable over the wick-cage 6 is a sleeve or cover 8 whose upper end-9 is closed so asto act as a piston in the outer sleeve 10, a duct I 11 communicating with the cylinder chamher 12, from which in turn a pipe 13 connects to, the intake manifold. The outer sleeve or cover 10 is also slidable, having a piston '14 in the cylinder chamber 12. An expansion sprin 15 bears .against the ,under side of the plstonand'is adjustable by virtue of the adjusting nut 16 which crowds the snugly fitting piston 7 along the extended endot sleeve 10.
When the-engine is at rest, the'pressurein, the intake manifold, as communicated through pipe 13 to the under surface of piston 14.- and on through duct 11 to the top of piston -9 is not different from the pressure effective upon the other sidesof the respective pistons. correspondingly the piston 9 with:sleeve8 is afiected only by gravity and the sleeve is down over the wick-cage, acting as a cover against evaporative waste of. the'liquid, and the outer sleeve 10 is held up by the spring 15. When the en 'ine. is running, the pressure from the inta e manifold through pipe 13 is less than that effective on the under{ side of piston 9 and the sleeve 8 is correspondingly raised up into the outer sleeve 10, 60 thus exposing the wick so that the chemical agent supplied thereby is volatilized. from discussion of the various possible theoretical explanations of why such results occur. When the engine speed exceeds that for which the spring 15 has been set, the piston 14 is carried down, taking with it the inner sleeve 8 and coveringthe wick. This prevents needless waste of'the knock-controlling agent when the engine conditions aresuch as not to require it.
In the modification shown in Fig, 3, a single sleeve 'or cover 20 is arranged to slide over the wick cage 21. The top of the cage forms an abutment which supports an'expan'sion spring 22 hearing above against an adjusting screw 23 in the iston 24 which is' attached to the sleeve. pipe 13 connects the cylinder chamber 26 below. the piston with the intake manifold, as m the form shown in Fig. 1, and the other relationships are-the same, the wick-tube 4 being 7 set in the air intake 1 and having the de tachable liquid-container 7 below. In this form, the sleeve 20 is held. up by the spring A 22 until the engine runs at aspeed exceeding thatfor which the spring 22 is ad usted, when the lessened ressure under the piston, I as communicated 5 0111 the intake manifold, 1
