Description

Internal-combustion engine arrangement
Technical field
The present invention relates to a kind of internal-combustion engine arrangement, it has an accumulator conduit that under high pressure absorbs fuel oil, stretches out a fuel duct from this accumulator conduit to each cylinder, and this fuel duct holds an automatically controlled fuel valve.
Background technique
If be used to control the electronic equipment generation fault of fuel valve in this internal-combustion engine arrangement, internal-combustion engine is out of service so.Special in the device that is used to drive navigation, the fault of this device causes serious consequence, can control it because ship has only under sail.But concerning the internal-combustion engine arrangement that uses on land, electronic device failure also causes bad consequence.
Summary of the invention
Thus, task of the present invention is to design a kind of like this internal-combustion engine arrangement, makes to make internal-combustion engine enter urgent running state when electronic device failure at once.
Can realize like this that according to this task of the present invention promptly in order to open fuel valve, replacedly each fuel valve is loaded by means of a kind of compressed fluid, this fuel valve allows to enter.For this reason, when electronic device failure in order to make internal combustion engine use a kind of fully independently system.
Compressed fluid valve according to the positioning control of the bent axle of internal-combustion engine preferably is set in the compressed fluid conduit between a compressed fluid storage and each fuel valve.In a kind of like this structure, internal-combustion engine itself carries out the control of fuel valve.
According to a kind of design proposal of the present invention, compressed fluid is a pressurized air.When the compressed fluid storage is the storage of starting air simultaneously, so just obtained a kind of very simple design proposal.
Description of drawings
Other feature and advantage are from remaining dependent claims and by means of drawing the explanation of accompanying drawing to an embodiment.Show among the figure:
Fig. 1 be in the internal-combustion engine arrangement according to a schematic representation of strength member of the present invention,
Fig. 2 is a sectional drawing of compressed fluid valve,
Fig. 3 is a sectional drawing of fuel valve.
Embodiment
Cylinder of internal-combustion engine is represented with 1 and the accumulator conduit is represented with 2 generally among Fig. 1.Accumulator conduit 2 is under high pressure supplied with fuel oil by means of a pump 3.Then, fuel oil arrives fuel valve 5 by fuel duct 4, and these fuel valves are attached troops to a unit respectively to a cylinder.In illustrated embodiment, internal-combustion engine has four cylinders 1.But the present invention is not limited to a certain number of cylinders.
Each fuel valve 5 links to each other with a compressed fluid storage 8 with a control unit 7 through a compressed fluid conduit 6.Pressurized air is as compressed fluid in an illustrated embodiment.Pump 9 of supplying with compressed fluid storage 8 links to each other with a transmission device 12 by an axle 11 that holds a cut-off clutch 10, and the bent axle 13 of internal-combustion engine can drive this transmission device.But also can pass through a Motor-Driven Pump 9.Transmission device 12 drives an axle 15 that is connected to control unit 7 by another cut-off clutch 14.In a similar manner, the known control unit that is used for starting air 16 links to each other with transmission device 12 by an axle 18 that holds a cut-off clutch 17.Control unit 7 and control unit 16 are connected on the compressed fluid storage 8 by a conduit 19,20 respectively.
For each compressed fluid conduit 6, control unit 7 holds a valve that has two locking bodies.These two locking bodies 21,22 interconnect by a valve rod 23 regularly and they can be operated to resist the effect of a Returnning spring 25 by a cam 24 on axle 15.With respect to compressed fluid conduit 6 closes ducts 19, this conduit is used to guide compressed fluid to locking body 21 in position shown in Figure 2.Locking body 22 is positioned at the enable possition simultaneously, discharges the gas in the compressed fluid conduit 6 in this position.Poppet stem 25 when rotating cam 24.This produces such result, and promptly locking body 22 closures and locking body 21 open wide and make compressed fluid to flow towards fuel valve.
Fuel valve 5 has a valve rod 26 with two locking bodies 27,28.Shown in operating position, locking body 27 sealing fuel ducts 4.Simultaneously locking body 28 is raised from its fitting surface and makes an input pipe 29 towards the cylinder release pressure.Can in this position, on valve rod 26, form pressure by a hole 30 in valve rod 26.This pressure also acts on the ball valve 32 by a hole 31 in the fixing part of a housing.Ball valve 32 remains on the locked position of coupler at this valve control unit 34 by 33 effects of a pressure spring.Valve control unit 34 is arranged on a lifting electromagnet in the housing 35 and links to each other with one in the known and mode that do not illustrate.Lifting electromagnet is controlled by electric control device.
Valve control unit 34 supports a pressure disk 36, and this disk has sealed a pressure chamber 37 on opening direction.Fluid can load by 6 pairs of pressure chambers of conduit 37.
When the internal-combustion engine proper functioning, wherein fuel valve 5 is automatically controlled, and cut-off clutch 10,14,17 is opened.If internal-combustion engine cuts out cut-off clutch 14,17 so because the electric control device fault is out of service.
When internal-combustion engine because electric control device fault and when out of service, continuously starting air being input in the single cylinder of internal-combustion engine by means of control unit 16 in known manner, as drawing by arrow among Fig. 1 38.Simultaneously, the bent axle 13 of internal-combustion engine begins rotation and by transmission device 12 live axle 15 when cut-off clutch 14 is closed, these axial control unit 7 guidings.Cut-off clutch 10 is closure when arriving desired speed of bent axle 13.Therefore, by the valve according to Fig. 2 of control unit 7, compressed fluid conduit 6 loads with on the predetermined conduit that is sequentially connected to compressed fluid the storage 8 19 and therefore pressure chamber 37 to fuel valve 5.The pressure disk 36 poppet valve control units 34 of each fuel valve make ball valve 32 can leave its fitting surface when the pressure that is subjected to acting on the valve rod 26.Therefore, the pressure on valve rod 26 has reduced.Because the part on the valve rod has been widened, the pressure that remains on 4 li of fuel ducts is valve rod 26 raises and therefore locking body 27 leaves it fitting surface.Fuel oil can for example flow to input pipe 29 from fuel duct 4 and flow to cylinder now.If continue the axle 15 that rotation has cam 24, Returnning spring 25 is closed described valve so.The pressure that discharges in the compressed fluid pipeline 6 by locking body 22 makes pressure spring 33 be pressed onto ball valve 32 on the locked position of coupler again through valve control unit 34 simultaneously.Next on valve rod 26, form pressure once more and make valve rod that locking body 27 is delivered on the operating position again, thereby end to flow to the fuel oil of cylinder.Next axle 15 raises other valve of the control unit 7 that is used for other compressed fluid conduit 6 according to this.
If internal combustion engine operation cut-off clutch 17 is so opened, make and do not import starting air herein.Cut-off clutch 10 remains closed and makes pump 9 be kept at the pressure in the compressed fluid storage 8.If the electronic control system of fuel valve 5 is recovered again, cut-off clutch 10,14,17 is opened again so.
Though when urgent operation, use pressurized air, because pressurized air is generally used for starting, also can be a kind of liquid as compressed fluid.
