Definitions
- the present invention relates to an engine comprising a rotary valve for transferring a fluid between a source of fluid and a combustion chamber of an internal combustion engine; said plug comprising at least one substantially cylindrical surface and a lateral flank.
- the prior art includes the document FR 2 559 208.
- the present invention relates more particularly to an engine comprising at least one rotary plug for controlling the admission of gas, in particular of an air-fuel mixture into a combustion chamber of an engine, comprising an intrinsic sealing system.
- the present invention applies to two-stroke or four-stroke internal combustion engines having one or more cylinders supplied by a gas, in particular an air-fuel mixture.
- the distribution of a fuel mixture in the combustion chamber can be carried out by parts moving in a reciprocating movement such as valves.
- the Applicant has protected, in patent application EP-A-0 435 730, a system of this type.
- the performance of the engine may be limited by the injection systems with valves, in particular with regard to the control of the start and the end of the injection and the cross section of the carburetted air (oscillation problems). .
- the bushels thus disclosed have an axis of rotation situated in a plane perpendicular to the axis of the cylinder, are pierced with a transverse channel for bringing the connecting channel and the combustion chamber into communication and are connected to means of drive allowing them to rotate as a function of the rotation speed of the engine crankshaft.
- Sealing devices are sometimes provided for this purpose, either upstream or downstream of each plug, or in both places.
- Patent application FR 2 559 208 relates to a plug for controlling the exhaust and / or the admission of gas from and / or to a combustion chamber to which one or more sealing members is applied.
- the improvement envisaged in this patent consists of lubrication and refrigeration of the contact surface between the sealing member (s) and the plug.
- the present invention provides an engine comprising a rotary valve of simple design, which does not require an additional and independent sealing member at the intake.
- the invention relates to an engine comprising a rotary plug according to claim 1.
- the face of the channel furthest from the longitudinal axis of the plug moves away from said axis from the inlet orifice.
- At least one of said plug flow channels may include a fuel trapping means.
- said fuel trapping means consists of an elbow formed by said channel and capable of retaining said fuel under the effect of the centrifugal force created by the rotation of the plug.
- the rotary valve is intended to control the admission of an air-fuel mixture into the combustion chamber of an internal combustion engine.
- the plug further comprises, from a certain distance from its end opposite to the combustion chamber, two channels arranged symmetrically with respect to a longitudinal plane.
- the plug may include an axial channel intended for its cooling.
- the plug can be mounted in a single-cylinder engine, placed at the entrance to the combustion chamber;
- several bushels can be mounted, each in the cylinder head of a combustion chamber of a multi-cylinder engine.
- a single axial cooling channel then preferably passes through all of the bushels.
- one or more bushels according to the invention can be fitted to an outboard motor, their longitudinal axis (s) then being able to be vertical.
- Figure 1 illustrates the arrangement of plugs in the case of a multi-cylinder engine.
- the cylinders 1 (three in number in this example) each capped by a cylinder head 2 whose hemispherical bottom defines the upper part of the combustion chamber 4 which is further delimited by the walls of the cylinder 1 and by the upper part of the piston 5.
- At each cylinder at least one injection orifice 3 provides communication between the combustion chamber 4 and at least one rotary plug 6 according to the invention.
- the plug 6 is rotatably mounted in the cylinder head 2 and controls the distribution of a mixture compressed air and fuel in the combustion chamber 4 since it is placed between the injection orifice 3 and a conduit (not referenced) for supplying compressed air.
- a fuel injection device 7 is preferably placed on the compressed air duct, at the inlet of the plug 6.
- each bushel of generally cylindrical shape, comprises at least one longitudinal shaft 8 which protrudes at least on one side and comes to bear on a bearing 9.
- the shafts 8 of the various bushels can be brought to an end at the end.
- each shaft 8 is hollow, which allows a coolant to pass through, for example, intended to cool the interior of said plug. This function is important given the rotation speeds of the plugs.
- a single cylindrical shaft 8 can cross all the bushels, or shaft sections can be mounted on either side of a cylindrical bushel.
- FIG. 2 shows in more detail a plug 6 according to the invention.
- the general shape of the plug can be cylindrical, with a longitudinal axis of rotation 10. As has been said, an axial channel 11, coincident with the axis 10 of rotation of the plug allows for example to circulate a coolant to the inside the bushel.
- a channel 12 intended for the flow of an air mixture under pressure-fuel for example, is provided inside the plug.
- the channel 12 is not straight, is preferably of variable section and has a first orifice or outlet orifice 121 cooperating with the combustion chamber 4 and a second orifice or inlet orifice 122, through which the mixture is introduced.
- the inlet orifice 122 belongs to the lateral surface of the plug and is placed at a non-zero distance from the axis 10 of rotation of the plug while the outlet orifice 121 belongs to the cylindrical surface of the plug while being offset radially with respect to the inlet 122.
- the outlet 121 is in any case placed farther from the axis 10 of rotation than the inlet 122.
- the neutral axis or fiber 123 of the channel 12 can be substantially parallel to the axis of rotation 10 of the plug 6.
- the fuel injector 7 opens near the inlet, inside the plug. More precisely, the injector 7 is oriented so that the axis of the jet that it generates is substantially contained in the same plane as the face 124 of the channel 12 closest to the axis 10 of the plug.
- the wall 125 of the channel 12 furthest from the axis 10 is inclined so that it moves away from the axis 10 from the end 122 of the plug.
- Figures 3 and 4 help to better understand the geometry of the plug at the inlet 122.
- two channels 12 A and 12 B arranged symmetrically with respect to a longitudinal plane of the plug.
- a larger number of channels can be provided without departing from the scope of the invention.
- Each channel 12 and each associated injector 7 must preferably be arranged as indicated above.
- Figure 3 which illustrates the zone into which the injector 7 enters shows the annular injection sector while in Figure 4 appears the partitioning of this sector into two zones 12 A, 12 B at the origin of the two channels. If two channels are provided, the plug will then rotate twice as fast as the engine in the case of an application to a two-stroke engine.
- a fuel trapping means can be provided, according to the invention, downstream of the inlet 122.
- This means can consist of a double deflection of the channel 12 which moves away then approaches the axis 10 of the plug, thus forming a "pocket” 126 that the centrifugal force contributes to filling.
- FIGS. 5, 6 and 7 illustrate the path of the channel 12 or more precisely of the two channels 12 A and 12 B provided according to this embodiment, downstream of the inlet 122.
- the trapping means is intended to complete and improve the seal produced at the level of the inlet 122 of the plug.
- the end 121 of the channel 12 allows an arrival of the mixture in the axis of the orifice 3, which is known per se.
- the rotary drive of the bushel can be achieved by any means known per se (belt, chain, sprockets, ...) so that it is controlled by the speed of the motor or a sub-multiple of this speed, depending the number of channels planned.
- the plug is capable of entraining the fuel particles towards the interior of the channel 12.
- the seal is completed by means of trapping the heaviest particles of the mixture.
- This means is advantageously capable of trapping the particles before the admission phase. This means makes it possible to retain the trapped fuel and prevent it from going out to one or the other of the ends of the plug as long as the intake is closed.
- the pressure variation allows said particles to be immediately reintroduced into the mixture and sprayed to the combustion chamber.
- the plugs according to the invention can be aligned as shown in Figure 1 thus providing a long axial channel 11 preferably intended for the passage of a cooling fluid.
- a single rotary drive is necessary for all of the plugs thus mounted.
- Figures 2 to 7 show the case of a plug crossed by two channels 12, it can be envisaged without departing from the scope of the invention that the two channels meet near the end 121 opening towards the combustion chamber .
- the plug (s) then have the same speed of rotation as the motor.
- these can also have the shape of a convergent-divergent along their length.
- plugs according to the invention can be made for example of aluminum, by molding.
