application filed December 16, 1914. Serial No. 877,560.
To all whom it may concern:
Be it known that I, ANDREAS R-ADOVANOVIC, a citizen of the Republic of Switzerland, residing at Zurich, Switzerland, have invented new and useful Improvements in Combus tion-Engines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawing, and to letters or figures of reference marked thereon, which form a part of this specification.
This invention relates to improvements in combustion engines with controlling piston and scavenging of the working cylinder across the axle of the cylinder.
The invention consists in the feature, that for the purpose to obtain a more rapid exhausting of the burned gases, additional exhaust openings are provided in the cylinder opposite the usual exhaust openings, which discharge into a chamber in connection with the exhaust channel, and that between this chamber and the scavenging air channel on the one side and the exhaust channel on the other side controlled shutting-off means are arranged.
In the combustion engines hitherto know with scavenging of the working cylinder across the axle of the cylinder the exhaustopenings are arranged only on the one half of the circumference of the cylinder. By the addition of a further row of exhaust openings opposite the usual exhaust openings (and above the openings for the entrance of the scavenging air) the cross-section of the exhaust openings is doubled in the beginning of the exhaust; consequently the fall of pressure to atmospheric pressure in the present structure takes place in onehalf the time that it does in structures provided with one row of exhaust openings.
. In the accompanying drawing two forms of execution of the object of the invention are shown by way of example.
Figure 1 is a vertical section through the cylinder of a combustion engine in a first form of execution, Figs. 2 and 3 are horizontal sections through the cylinder on the lines AB and CD respectively of Fig. 1, and Fig. 4 a view of the whole engine on a reduced-scale; Fig. 5 shows in a horizontal section through the cylinder a further form of execution of a part of the object of the invention.
In the Figs. 1 to 4 of the drawing 2 denotes the working cylinder of the combustion engine and 7c denotes the piston thereof; 7" are the openings in the cylinder jacket for the entrance of scavenging air in the cylinder and f is the scavenging air channel, a are the usual exhaust openings arranged in the cylinder jacket opposite the openings f and a are the additional exhaust openings, which are arranged in the cylinder opposite the openings (1 and above the openings 7 and discharge into the chamber r situated on the outside of the cylinder.
a denotes the exhaust channel, in which the exhaust openings at and the chamber 7" discharge; o is a valve which serves to shutoff the chamber 7 toward the scavenging air channel f This valve is controlled by a lever Q1 41' and a cam disk w fixed on a shaft to, which latter is driven by a crank shaft b of the engine by means of a control ling shaft 0 and bevel gears d (Fig. 4). 0 denotes throttle valves arr nged between the exhaust channel a and the chamber 1', z. e. at the places where these rooms run into each other. by means of a lever 9 a rod 16 a lever 39 and a common lever 19 by the cam disk to fixed on the shaft to.
The working of the engine is the followmg: During its forward stroke the piston 7:: opens the openings at and oi so that the burned gases can stream out through the openings at directly into the exhaust channelv a in the direction of the arrows at and through the openings a into the chamber 7' in the direction of the arrows m; the throttle valves ;0 being in the open position (drawn in full lines) the burned gases escape from the chamber 1- into the exhaust channel a (Fig. 2). It is clear that by exhausting through the openings a and the additional openings 05 the exhaust takes place much quicker, than by exhausting through the exhaust openings a alone. By its further forward stroke the piston k opens the openings f for the scavenging air, which now enters into the cylinder 2 to expel. the exhaust gases in a known manner. At the same time the throttle valves 7? are closed (as indicated in dotted lines) and the valve 4) is opened. The scavenging air now flows into the chamber 7' and rom here through Each of these valves is controlled the openings a in the cylinders in the direction of the arrows Z. During its return stroke the piston is first closes the openings 7, but while the throttle valves are still closed and the valve 4) is still open, the scavenging air is always streaming into the cylinder till the openings a'and a are closed by the piston. By the addition of the openings a not only the exhaust is accelerated,
but also the duration of the scavenging is extended, from the moment the piston closes the openings f to the moment it completes the closing of the openings at and a Instead of the throttle valves ;0 and the valve a any other throttleor shut-ofi' means can be provided. An example of such a further form of execution of the object of the invention modified with regard to the throttle means is illustrated in Fig. 5. Instead of the throttle valves 7) vertical slots 8 are provided in the outer walls of the chamber 1- that is at the places Where this chamber runs into the exhaust channel a. Through-out these slots air with a higher pressure than that of the scavenging air is blown-in in the direction toward the middle of the cylinder in such a manner that at each side an air wall is formed serving as throttle means, which prevent a directly entering of the scavenging air from the chamher 1* into the exhaust channel (1, For the rest the working of the engine is the same as in the first described example of execution.
The air with a higher pressure than the scavenging air is supplied through a pipe 8 provided with a shut-01f valve 8 the operation of these valves and of the valve 4) th same as thecperation of the throttle valves 72 and the valve 'v in the first described example of execution of the engine.
