Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improved internal combustion engine, and more particularly to a two-cycle internal combustion engine in which the first K operating process is performed in two strokes or one rotation of the Krasif shaft. This does not preclude application to internal combustion engines.

In two-cycle internal combustion engines, when the pistol moves upwards, the gas mixture is pressurized, so that at the end of this stroke ignition or possibly injection occurs, so that the expansion of the scum causes the pistol to move downwards, and It is known that for this purpose, at the end of the downward stroke, the exhaust opening is first opened, so that a pressure reduction is obtained, and the scavenging opening is opened a little later.

It is also known that during the first part of the first stroke the scavenge and exhaust ports remain open at four o'clock, and then during the rise of the stroke the scavenge and later the exhaust are closed. be.

A conventional internal combustion engine with scavenging and exhaust ports is very simple and reliable. However, this type of internal combustion engine has a relatively low efficiency (mainly because a very large amount of fresh gas escapes through the exhaust port during the scavenging phase, and due to the very structure of the internal combustion engine, the scavenging port is We must acknowledge the fact that due to the fixed position with respect to the exhaust vents, no adjustment between them is possible.

In such two-cycle internal combustion engines, valves are incorporated, thereby effectively enabling the aforementioned regulation and thus improving efficiency reduction by allowing fresh gas to escape. However, the rotation speed of such an internal combustion engine is 40 per minute.
It is limited to 00 to 4500.

The present invention relates to a two-cycle internal combustion engine, whereby the time during which the scavenging port is open and the exhaust time are adjusted to an appropriate KvI4trJ by converting one side to the other &141 regardless of the position of the exhaust gas
It is very advantageous for the internal combustion engine to rotate at high rotational speeds, for example as in the case of competing internal combustion engines.

In the second case, the internal combustion engine according to the invention can be configured as a four-stroke internal combustion engine, thereby making it possible to better regulate the intake and exhaust air of the internal combustion engine.

The internal combustion engine according to the invention is primarily characterized by having in its combustion chamber at least one valve floating within this chamber.

BRIEF DESCRIPTION OF THE DRAWINGS In order to better illustrate the characteristics of the invention, certain embodiments will be described below with reference to the accompanying drawings, in a non-limiting sense.

The two-cycle internal combustion engine according to the present invention essentially consists of a classif case 15, a cylinder 2, a cylinder, and a cylinder 7, and a cylinder head 3.
These are made from one part to simplify the explanation. The entire body is provided with an intake port 4, which enters into the syringe 2 through an opening 6, and is provided with holes 8 for attaching a connecting portion between the syringe case 1 and the syringe 2, an exhaust lower and an ignition brush 9. It is being

The internal combustion engine further comprises a cylinder head 11 fixed on a cylinder shaft 10, to which a connecting rod 13 is connected by means of a shaft 12, which can itself vibrate and is therefore pistol 15
It is assembled into.

According to the embodiment shown in FIGS. 1 to 3, the silicator head 3 is made in the shape of a hemisphere with a concave inner surface, so that a pulse in the shape of a spherical T-shape 1-16 is formed in this hemispherical cavity. The valve opens the exhaust lower and is also provided with a hole 8 for the ignition brush 9, the spherical segment 16 being connected with a rod 17, the opening 1 being inserted into the drive disc 18 in a suitable manner. attached to the t-lid 3 to the cylinder in such a way that the disc rotates about the A-A axis, thereby fixing the O-end 7 at a suitably defined angle in the disc 18. and is guided therein.

The 0-piece 17 should be adapted so that the spherical sejime, :J, can freely move in the combustion chamber, in other words, the 0-rad 1 is mounted freely and rotatably in the disk l-8. .

If necessary, a crown gear fixed with respect to the housing of the internal combustion engine and a meshing gear can be provided on the shaft 17, thereby eliminating the stoppage of the spherical gear 16 with respect to the disc 18.

The functioning of the internal combustion engine according to the invention is very efficient.

In reality, the exhaust lower is closed during compression stroke (
1), so that the compressed fuel-air mixture can be automatically ignited by the self-contained ignition jet 9, so that towards the end of the expansion stroke the scavenging port 6 is freed by the pistol 15, the exhaust lower is trapped to be opened since a partial exhaust of the burnt scum is already obtained, so that during the upward movement of the pistol 15, the scavenging air 06 is connected to the exhaust lower. At the same time, the position of the spherical sedge 16 can be adjusted in such a way that it remains open only for a very short time, thus allowing as little unburnt residue as possible to escape through the exhaust lower.

In this way, the simultaneous opening of the scavenging port 6 and the exhaust lower can be adjusted in a suitable manner, so that the efficiency of the two-cycle internal combustion engine is increased, in particular by less escape of unburned gases, thereby A variant of the embodiment is shown in FIGS. 4 and 5, which is substantially the same as that according to FIGS. 1 to 3, but with the following differences: , M4 the valve or spherical valve 16 is replaced by a valve in the form of a disc 19 which vibrates to and fro, while in FIG. It has been replaced by a cylindrical object 20.

The function of the internal combustion engine shown in FIGS. 4 and 5 is similar to that described above.

It is understood that the invention is in no way limited to the embodiments described by way of example and shown in the accompanying drawings, and that such internal combustion engines do not depart from the scope of the invention (depending on the shape and dimensions). It is clear that it is made with 5.

Therefore, if air is compressed in this internal combustion engine and the ignition tube is replaced by a sector of the diesel fuel oil phase, this internal combustion engine can be suitable for being driven by that fuel.

Exhaust gas must be removed and/or components 16.1
It is also clear that improvements can be made by appropriately contouring 9 or 21.

Although shown in the drawings and embodiments, whereby the intake air is ensured by a classical case boss, it is clear that the same effect can also be achieved using a separate scavenge position.

In some embodiments of the two-cycle internal combustion engine, in combination with the above, a fine pulse and a main pulse may be provided, which are placed in close proximity to the ignition valve, through which part of the exhaust scum is removed. Ru.

In such a case, these valves function as auxiliary gas exhaust ports, such that the exhaust lower remains as the main exhaust or the exhaust lower functions as a secondary exhaust.

If the internal combustion engine according to the invention is configured as a four-stroke internal combustion engine, either the inlet or the outlet is opened and closed by the above-mentioned spherical tether, and the exhaust or intake respectively takes place in a customary manner through conventional valves. .

It is also possible to construct a four-stroke internal combustion engine, in which case the inlet and the outlet are respectively opened and closed by spherical sedges.
