Definitions

  • the invention relates to an exhaust system in a manually operated implement driven by an internal combustion engine.
  • the object of the invention is to improve an exhaust system of the aforementioned type in such a manner that the fouling effect is avoided.
  • the exhaust pipe is connected downstream of a muffler with the condensate guide element being located in a section of the pipe outside the muffler. Hot exhaust emissions do not flow around this section of the exhaust pipe.
  • the comparatively cool environment favors the formation of condensate.
  • the position of the condensate guide element in this area causes the condensate substance to be reintroduced into the exhaust gas flow almost directly at the place of condensate formation.
  • the condensate guide element is advantageously positioned in the immediate vicinity and upstream of the outlet end. A renewed condensing and depositing of the condensate substance returned to the exhaust gas stream is eliminated.
  • the condensate guide element forms a separation point for the exhaust gas stream in its cross-section.
  • separation point is not limited to an angular edged shape. It covers any aerodynamic shape which narrows the flow cross-section of the exhaust pipe and which, in contrast to a venturi-type design, generates flow separation from the surface with subsequent swirl formation.
  • the flow separation caused by the condensate guide element and the subsequent swirl formation support the effect of the exhaust gas stream as it carries the film of condensate on the walls along with it.
  • the condensate guide element runs in a spiral shape along the internal wall of the exhaust pipe.
  • the spiral shape which extends axially permits a restricted degree of axial movement of the film of condensate deposited on the walls and thus its distribution over the axial length of the condensate guide element.
  • the condensate guide element is able to return the deposited condensate to the exhaust gas stream with greater efficiency.
  • downstream end of the condensate guide element is located in the area of a center line of the exhaust pipe. Residual condensate which has not been returned the length of the condensate guide element into the exhaust gas stream, runs in the direction of flow of the exhaust gas along the condensate guide element to its downstream end. Here it is located in the area of the center line where it can be better removed from the exhaust gas stream and discharged. The formation of condensate residues is avoided.
  • the condensate guide element is designed as a spiral-shaped wire spring.
  • the circular shape of the wire cross-section has proved effective both in collecting the stream of deposited condensate and in directing the flow of the exhaust gas stream and forming swirls.
  • the upstream end of the wire spring is preferably bent radially inwardly.
  • the inwardly bent wire end can easily be used as an assembly aid.
  • the end of the wire which projects into the flow cross-section helps to form swirls and thus to improve the reabsorption of the condensate.
  • the wire spring is held pre-tensioned radially in the exhaust pipe.
  • this radial pre-tensioning also ensures the application of a radial force pushing the spring and the internal wall together. A sealing effect can be observed in this area.
  • the film of condensate is unable to creep between the wire spring and the pipe wall. In fact, it is diverted radially inwardly around the wire cross-section of the wire spring where optimum conditions for reintroduction into the exhaust gas stream prevail.
  • FIG. 1 shows an overview of a manually operated implement based on the example of hedge clippers with an exhaust system illustrated in the form of a block diagram
  • FIG. 2 shows a perspective, transparent view of the exhaust pipe of the arrangement illustrated in FIG. 1 with details of the condensate guide element positioned therein;
  • FIG. 3 shows a section through an enlarged schematic view of the flow conditions in the area of the wire cross-section of the condensate guide element in the arrangement illustrated in FIG. 2 ;
  • FIG. 4 shows a perspective, detailed view of the condensate guide element as illustrated in FIG. 2 in the form of a wire spring
  • FIG. 5 shows a variant of the wire spring illustrated in FIG. 4 with one end drawn into the area of the center line.
  • FIG. 1 shows a perspective view of a manually operated implement based on the example of hedge clippers which is driven by an internal combustion engine ( 1 ).
  • the implement in question might also be a brushcutter, a parting-off grinder or a chain saw, for example.
  • a front handle ( 15 ) and a rear handle ( 16 ) are provided for guiding the hedge clippers by means of which a shearing blade ( 18 ) driven by the internal combustion engine ( 1 ) can be guided along the foliage to be cut.
  • the internal combustion engine ( 1 ) is a two-stroke internal combustion engine with total-loss lubrication in which a portion of lubricating oil is mixed with the fuel for operation. It is also possible to provide separate lubrication with a separate lubricant reservoir and an at least approximately loss-free lubrication system, in a four-stroke engine, for example.
  • the exhaust emissions created when the internal combustion engine is in operation are discharged into the environment by an exhaust system which is covered by the housing ( 17 ) and indicated in the illustrated by means of a block diagram.
  • the exhaust system comprises a muffler ( 7 ) downstream of which is connected an exhaust pipe ( 2 ).
  • a stream of exhaust gas indicated by means of an arrow ( 3 ) passes through first the muffler ( 7 ) and then the exhaust pipe ( 2 ) until it discharges into the environment at the free outlet end ( 4 ) of the exhaust pipe ( 2 ).
  • an inner pipe section ( 9 ) of the exhaust pipe ( 2 ) projects into the muffler ( 7 ).
  • a condensate guide or condensate-guiding element ( 6 ) Positioned in the outer pipe section ( 8 ) in the immediately vicinity and upstream of the outlet end ( 4 ) is a condensate guide or condensate-guiding element ( 6 ) which is described in greater detail below.
  • the exhaust pipe ( 2 ) shown in FIG. 1 is illustrated in an enlarged and transparent form in FIG. 2 .
  • the exhaust pipe ( 2 ) has a circular cross-section and runs along a center line ( 12 ).
  • the condensate guide element ( 6 ) Positioned at the outlet end ( 4 ) is the condensate guide element ( 6 ) which is designed as a spiral shaped or helical wire spring ( 14 ) in the embodiment shown.
  • the spiral-shaped wire spring ( 14 ) or coil spring is inserted radially pre-tensioned into the free end of the exhaust pipe ( 2 ) near the outlet end ( 4 ).
  • the wire spring Due to the radial pre-tensioning force, the wire spring is fixed in position in both a frictional and positive fit and conforms to the internal wall ( 5 ) of the exhaust pipe ( 2 ) on the inside.
  • the exhaust pipe ( 2 ) is also provided with an axial retainer ( 21 ) at the outlet end ( 4 ) to fix the position of the wire spring ( 14 ) axially.
  • the exhaust pipe ( 2 ) Upstream of the condensate guide element ( 6 ), the exhaust pipe ( 2 ) provides the exhaust gas stream ( 3 ) with an undisturbed, circular flow cross-section. This flow cross-section is narrowed several times circumferentially and radially inwardly by the wire spring ( 14 ) which rises up from the internal wall ( 5 ).
  • the flow conditions at the condensate guide element are shown in an enlarged, schematic view in FIG. 3 .
  • the circular cross-section of a wire ( 22 ) of the wire spring ( 14 ) ( FIG. 2 ) is pressed against the internal wall ( 5 ) of the exhaust pipe ( 2 ).
  • the course of the exhaust gas stream ( 3 ) is shown by means of flow lines. In the interests of clarity only two ( 27 ) of these flow lines, located near the wall, are shown in the drawing.
  • a film of condensate ( 23 ) has formed on the internal wall ( 5 ) upstream of the wire ( 22 ).
  • the film of condensate ( 23 ) endeavors to migrate in the direction of the exhaust stream ( 3 ) towards the outlet end ( 4 ) ( FIG. 2 ).
  • the view shown in FIG. 3 illustrates how as a result the film of condensate ( 23 ) builds up upstream of the wire ( 22 ) and is directed away from the internal wall ( 5 ) towards the center line ( 12 ) by the condensate guide element ( 6 ) ( FIG. 2 ).
  • the aerodynamic shape selected for the circular cross-section of the wire ( 22 ) causes a break in the laminar flow of the exhaust gas stream ( 3 ). Downstream of the maximum distance to the internal wall ( 5 ), a separation point ( 26 ) is formed after which the flow separates off from the surface of the condensate guide element ( 6 ) and the subsequent section of the internal wall ( 5 ). Thus the swirls ( 25 ) indicated are formed. Once a significant portion at least of the exhaust gas stream ( 3 ) close to the wall downstream of the condensate guide element ( 6 ) has formed swirls, the separation point ( 26 ) formed in relation to the cross-section of the wire ( 22 ) manifests itself as a separation line along the length of the wire material.
  • the circular cross-section of the wire ( 22 ) shown other, for example angular, cross-sectional shapes may be useful for the formation of an aerodynamic separation point ( 26 ).
  • the narrowing of the free flow cross-section due to the condensate guide element ( 6 ) causes a local acceleration of the exhaust gas stream ( 3 ) which is shown in the illustration by means of the decreasing distance between the flow lines ( 27 ) and which reaches its maximum value somewhere in the area of the maximum radial lifting or elevation of the condensate guide element ( 6 ) from the internal wall ( 5 ).
  • the exhaust gas flow ( 3 ) and/or the weight direct the film of condensate ( 23 ) around the cross-section of the wire ( 22 ) into the aforementioned area.
  • FIG. 4 shows an individual, perspective view of the wire spring ( 14 ) illustrated in FIG. 2 .
  • the wire spring ( 14 ) usefully comprises some two to six screw-like spirals ( 10 ).
  • the embodiment shown illustrates a spiral ( 14 ) with slightly more than four turns.
  • the wire spring ( 14 ) is also curved radially inwardly at its upstream end ( 13 ) as a result of which the end ( 13 ) projects inwardly into the flow cross-section of the exhaust gas flow ( 3 ) ( FIG. 2 ).
  • FIG. 5 A variant of the wire spring ( 14 ) shown in FIG. 4 is illustrated in FIG. 5 .
  • the spirals ( 10 ) run in a spiral against the internal wall ( 5 ) of the exhaust pipe ( 2 ), as is also the case in the embodiment illustrated in FIGS. 2 and 4 .
  • the longitudinal axis ( 28 ) coincides with the center line ( 12 ) of the exhaust pipe ( 2 ) ( FIG. 2 ).
  • the downstream end ( 11 ) of the wire spring ( 14 ) thus lies at least approximately on the center line ( 12 ) of the exhaust pipe ( 2 ) or in the center of the flow cross-section of the exhaust gas stream ( 3 ).
  • the embodiment illustrated in FIG. 5 corresponds to that shown in FIG. 4 in so far as all the other features and reference numerals are concerned.
  • the condensate guide element ( 6 ) is designed as a spiral-shaped wire spring ( 14 ).
  • a metal strip, a contoured exhaust pipe ( 2 ) wall or comparable other designs may also be advantageous.
  • an annular aperture-like design may also be useful, it also being possible to positioned several circular disks one after another in a cascade.
