Definitions
- the invention relates to an exhaust system for a work vehicle, with one engine, one exhaust pipe of the engine and one with muffler connectable to the exhaust pipe.
- Agricultural harvesting machines such as. B. in US 6,257 977 A are used to agricultural Harvest goods from a field.
- Occasions when such harvesters are transported or must be driven on a road to the field reach or return from the field.
- Some government agencies have imposed noise limits on commercial vehicles based on drive on public roads. Especially European ones Regulatory noise limits are strict. With increasing engine size and increasing performance requirements it becomes more difficult to comply with these restrictions.
- An increased back pressure typically has one reduced available engine power, lower fuel economy and possibly a reduced lifespan of one Turbocharger result.
- the object on which the invention is based is seen in provide a muffler that muffles the noise during Road transport reduced to permissible values, but at Operation in a field does not create excessive back pressure on the engine exercises.
- the maximum performance requirements the engine of a self-propelled work vehicle, in particular of a combine harvester, not when transported on a road occur in which the noise restrictions must be observed.
- the maximum performance requirements occur in the field.
- For transport by road is the performance requirement in the Usually less than three quarters of the maximum rated power, so that the speed of the engine can be reduced and the associated output flows much smaller than the maximum flows are.
- the present invention is based on a silencer can be dimensioned such that it diminished in these Ejection flows the noise requirements during transport can meet on a street, but for an operation with full Performance in a field would be too restrictive.
- a bypass line for an exhaust system for a Work vehicle suggested in one essentially closed state, a maximum attenuation for the Provides transportation on a road, d. H. a relative high back pressure, and in an essentially open Condition for operation on a field at full power provides reduced flow restriction, d. H. one relatively low back pressure.
- a valve device upstream of the muffler active in road operation enables the Open and close the bypass line. It can be done manually or operated automatically.
- the noise level is reduced to acceptable levels during road transport without a performance limitation during operation in the field of the engine due to excessive back pressure.
- the valve device can have a guide flap that Open and close the bypass line and preferably also the Close and open the line leading to the first silencer can.
- a membrane can be used to guide the flap like this to control that the first muffler when operating the Work vehicle is bypassed in a field.
- the exhaust system can be configured such that the first silencer is completely bypassed and the exhaust gases completely by the Bypass line to be directed. But it can also be a system that only redirects part of the exhaust gas to the To reduce back pressure while still some flow is maintained by the first silencer. Thereby would reduce the noise level and some back pressure maintained.
- the system could also be configured in this way be that the exhaust gas from the first, more restrictive Muffler fully or proportionally (i.e. partially) in one less restrictive, second silencer is redirected. Alternatively, the system could be configured such that the second silencers not necessarily less restrictive is, but the combined flow path through the first and the second silencer is significantly less restrictive than the flow path only through the first silencer.
- the amount of flow through the bypass line depends from the position of the guide flap.
- the position of the guide flap can be controlled by a membrane that is positive Air pressure (overpressure), which is caused by a Control air line supplied from the engine intake manifold the air pressure of a turbocharged engine from the Load of the motor is dependent. Alternatively, one could Suction motor to move the vacuum in the inlet manifold Membrane are used.
- In the control air line can more precise control an electromagnetic valve inserted become.
- the electromagnetic valve can be controlled preferably an electronic control unit of the vehicle, to be controlled.
- the modulation degree of the guide flap can be the electronic control unit proportional to the Power requirements of the engine can be controlled. If the Performance requirements are low, all exhaust gases can pass through the first silencer are directed. If the Performance requirements can increase, progressively increasing Exhaust gas amounts by opening the flap in the Bypass line to be redirected. Therefore, even on the Field where the road noise restrictions are not applicable a maximum amount according to the performance requirements Noise reduction achieved.
- the guide flap can be opened in the Cabin arranged lever and one up to the guide flap extending pressure and tensile force transmitting cable manually be positioned.
- a electromagnetic valve with a manually operated Selection switch connected and with pressurized air or Vacuum must be applied to the pressure on the Manually control the flap of the coupled membrane.
- alternative could be biased by a spring to the Bypass to keep closed, but by increasing Open back pressure.
- the bypass system could be deactivated electronically if the work vehicle is shifted into a higher gear, the is only used for driving on a road, d. H. about that to force all exhaust gas through the first silencer. This would open up the noise level restrictions when driving adhered to the streets.
- FIG. 1 illustrates a motor 50 that is equipped with a Exhaust pipe 54 is connected to a valve device 56 leads.
- the valve device 56 has two outlets connected, a first outlet 60 which is connected to a Silencer line 62 is connected, and a second Connection 66, which is connected to a bypass line 70.
- the silencer line 62 is provided with a first silencer 72 connected, which is connected to a first end pipe 74.
- the bypass line 70 can be equipped with a second silencer 76 be connected, which is connected to a second end pipe 80.
- the second silencer 76 can be a less constricted Be silencers to a substantial proportion of the total to let out the discharged river with less back pressure than the first muffler 62, or it could be more or less be more restrictive than the first muffler 72, the Passage of all the exhausted gas through both Silencer 72, 76 a reduced back pressure during the Field operation of the combine.
- the second silencer 76 are completely eliminated and the bypass line 70 can be connected to the end pipe 80 or formed in one piece with it his.
- a movable one is located within the valve device 56 Guide flap 84.
- the guide flap 84 is about a pivot point 86 pivotable. Is in the position shown in Figure 1 the flapper 84 in one position so that the entire Ejection amount flows through the first silencer 72.
- the Guide flap 84 is connected to an actuating rod 90 which is connected to a membrane 94.
- the membrane 94 is located in pressure connection with a control air line 104
- Control air line 104 is pressurized Air intake manifold 110 connected to the combustion air provides internal combustion engine 50. If the Boost pressure increases in the air intake indicator 110, the Guide flap 84 opened proportionally, so that a lot of Combustion gas to the outlet 66 of the valve device 56 is redirected. The back pressure in the outlet would be higher performance requirements decreased.
- An electromagnetic valve 106 can enter the control air line 104 be looped in.
- the valve 106 can be controlled C, like an electronic control unit with a microprocessor, be connected to transmit signals. Such controls are connected to the transmission of the combine for signal transmission and control engine speed and output power of the transmission to the wheels. Such controls are used to optimize the efficiency of the vehicle.
- the Control can progressively open the bypass line 70 if in the field performance requirements on the combine be put.
- the electromagnetic valve 106 may be replaced by one of the Operator controlled electrical switches are controlled which opens or closes the electromagnetic valve 106.
- FIG. 2 illustrates the system from FIG. 1, the Guide flap 84 is moved to a position in which it Exhaust path through the silencer 72 closes and the Bypass route opens. That would be with this ejection configuration Exhaust system less restrictive and would have a higher from Motor 50 result in deliverable power when on is operated in a field where noise restrictions in the Comparison with the operation during transport on roads are less important.
- FIG. 3 shows an alternative embodiment in which a manually operable, tension and pressure transmitting cable 202 with an operator controlled handle or lever 204 connected is.
- the cable 202 is with an angle lever 208 connected, which at a point 210 with the frame of the Combine is connected.
- An opposite end of the Angle lever 208 is connected to the actuating rod 90.
- Pushing down or pulling lever 204 would make the connection 66 of the bypass line 70 open or close.
