Definitions

  • pavers and material feeders are used to create paved surfaces.
  • Commonly used pavers and material feeders are powered by an internal combustion engine.
  • the exhaust gases from the engine are expelled through a long exhaust pipe at the height of the driver's cab to keep them away from the operator.
  • the exhaust pipe is typically mounted on a muffler, which, along with the muffler, is vertically attached to the engine hood in front of the operator's platform.
  • the problem is that the exhaust pipe and the associated silencer obstruct the view of the operator on the control panel. Furthermore, the outward-facing exhaust pipe and silencer are exposed to all weather conditions, which often leads to damage to the exhaust pipe and silencer due to rust.
  • the FR 2 170 753 A5 This describes an exhaust system located under the hood of a construction machine.
  • the exhaust system includes an engine from which an exhaust pipe extends towards a finned opening.
  • the exhaust pipe has a curved end that directs the exhaust gases from the engine into the opening, where they exit along with a cooling airflow generated by a fan and a radiator.
  • the US 5,228,530 A This refers to a lawn tractor whose engine is located under a hood behind the driver's seat.
  • the engine consists of a motor from which exhaust gases are routed through an exhaust pipe and a muffler to an exhaust outlet with a grille.
  • the exhaust gases exit the engine through a section of exhaust pipe and are then carried out through the exhaust outlet with the grille by a cooling airflow generated by a radiator and a fan.
  • the US 4,872,308 A This refers to a machine with a drive unit that includes a damper.
  • the damper is cooled by compressed cooling air generated by a fan, thus reducing the risk of fire in the engine compartment.
  • a mixing chamber is located above an exhaust outlet for the damper to mix the exhaust gases flowing from the damper with cooling air and direct the mixture to an outlet in the engine hood.
  • the invention is based on the objective of improving a construction machine by means of simple design features in such a way that exhaust fumes from the construction machine can be kept away from the operating personnel.
  • the exhaust pipe is not located on the hood of the construction machine.
  • the exhaust pipe is located in the engine compartment, with the exhaust pipe ending under the hood.
  • the exhaust pipe in this invention terminates under the engine hood, the operator has improved visibility while operating the construction machine. Furthermore, the exhaust pipe is protected from dirt and adverse weather conditions under the hood, thus improving its functionality and extending its service life. Additionally, the exhaust pipe, located in the engine compartment, is not at risk of damage during transport. Moreover, complex and expensive folding or plug-in devices for the exhaust pipe are unnecessary.
  • the exhaust pipe includes at least one exhaust outlet nozzle, which directs the exhaust flow and also terminates under the engine hood.
  • a limited and controlled quantity of exhaust gases can leave the engine compartment of the construction machine through the exhaust outlet nozzle.
  • the invention provides an exhaust outlet opening in the engine hood, which is flow-optimized in relation to the exhaust pipe, in particular the exhaust outlet nozzle.
  • the exhaust outlet opening provided in the engine hood ensures the unimpeded escape of combustion gases through the hood.
  • the exhaust outlet nozzle or exhaust pipe opens into the exhaust outlet opening. This ensures that the exhaust gases flowing from the exhaust pipe or exhaust outlet nozzle are completely directed into the exhaust outlet opening.
  • At least one exhaust opening is provided in the engine hood to dissipate waste heat from the engine. This prevents the engine from overheating and being damaged as a result.
  • the at least one exhaust air opening comprises flow ribs to give an outgoing exhaust air stream an outflow direction.
  • the exhaust gas outlet is located next to the exhaust air opening. This ensures that the exhaust gas flow is directed into the exhaust air flow, thereby enabling efficient removal of the exhaust gases from the construction machine.
  • the exhaust system includes at least one cooling fan, which is intended for cooling the engine.
  • the cooling fan has a speed control.
  • an airflow produced by the cooling fan is provided for the removal of engine heat, wherein the airflow heated by the engine heat forms an exhaust airflow from the cooling fan to carry away the combustion gases of the engine.
  • the exhaust airflow Upon exiting the exhaust airflow from the exhaust opening formed in the engine hood, the exhaust airflow meets the exhaust gas flow from the exhaust outlet opening, surrounds and dilutes it, and directs it away from the exhaust outlet opening and away from the operating personnel.
  • a diffuser is provided that can be used to dilute and cool the combustion gases.
  • the diffuser allows the exhaust gases to expand and cool immediately after exiting the combustion engine, thus preventing excessive heating of the exhaust pipe. Furthermore, the diffuser improves the dissipation of generated engine heat, and the cooled exhaust gases released by the diffuser do not unnecessarily raise the ambient temperature of the construction machine's engine.
  • the exhaust pipe is connected to an exhaust aftertreatment system. This system widens and slows the exhaust flow and reduces its vibrations.
  • the exhaust aftertreatment system can include a particulate filter, a catalytic converter, a silencer, etc.
  • the exhaust aftertreatment device is preferably located in the engine compartment of the construction machine. This also makes it possible to protect the exhaust aftertreatment device from adverse weather conditions.
  • the Figure 1 Figure 1 shows a section of a construction machine 100, which includes an exhaust system 1 according to the invention.
  • the construction machine 100 is in particular a road paver or a feeder.
  • the exhaust system 1 has an engine compartment 2 with a hood 3.
  • An internal combustion engine 101 for powering the construction machine is located in the engine compartment 2.
  • An exhaust pipe 4 is positioned in the engine compartment 2, under the hood 3. The exhaust pipe 4 extends upwards to an upper surface of the hood 3, but does not protrude from the hood 3.
  • Exhaust outlet nozzles 5 are provided at one upper end of the exhaust pipe 4, which determine the direction of the exhaust flow as it exits the exhaust system.
  • the exhaust outlet nozzles 5 are arranged side by side, but can also be arranged in any other configuration on the exhaust pipe 4. Furthermore, the exhaust outlet nozzles 5 can have different diameters or different heights.
  • the exhaust outlet nozzles 5 open into the exhaust outlet opening 6. Although it is evident from the Figure 1 If not shown, it is possible that the exhaust outlet nozzles 5 protrude into the exhaust outlet opening 6 over a certain length without protruding significantly from the hood 3.
  • an exhaust opening 7 is provided in the engine hood 3, which is fluidically connected to a cooling fan 102.
  • the cooling fan 102 transports the waste heat from the engine 101 to the exhaust opening 7, where the cooling airflow exits the engine compartment as exhaust air. 2 exits.
  • the exhaust opening 7 occupies a larger part of the surface of the engine hood 3 than the exhaust outlet opening 6.
  • the exhaust outlet opening 6 is located in a lower left area of the exhaust opening 7.
  • the exhaust opening 7 has flow ribs 8 arranged parallel within the exhaust opening 7.
  • the flow ribs 8 assume an inclined position to direct the exhaust airflow forward away from the hood 3.
  • the exhaust outlet opening 6 is located along two sides of the exhaust air opening 7, with the exhaust outlet opening 6 being positioned in front of and beside some flow fins 8, so that when the exhaust air stream exits the exhaust air opening 7, it carries the exhaust gas stream coming from the exhaust outlet opening 6 forward away from the engine hood 3. It is also provided that the exhaust air stream guided by the upper flow fins 8 flows out above the exhaust outlet opening 6, thereby covering the exhaust gases exiting the exhaust outlet opening 6 and keeping the exhaust gases away from the operating personnel.
  • an exhaust aftertreatment device 9 is flanged to the exhaust pipe 4.
  • the exhaust aftertreatment device 9 is located inside the engine compartment 2, below the engine hood 3. Together with the exhaust pipe 4, the exhaust aftertreatment device 9, which includes, for example, a particulate filter, a catalytic converter, a silencer, etc., ensures optimal removal of the combustion gases from the combustion engine.
  • Figure 2 shows an engine arrangement 200, as it can be used for a construction machine 100 according to the invention.
  • the engine arrangement 200 is shown.
  • Figure 1 The illustrated embodiment shows the Figure 2 a diffuser 103, which is connected to the exhaust aftertreatment device 9 via the exhaust pipe 4.
  • the diffuser 103 is designed to dilute and cool the combustion gases.
  • the diffuser which is not shown installed in engine compartment 2, is, according to the invention, fluidically connected to the one in Figure 1
  • the exhaust outlet opening 6 shown is aligned and does not protrude from it.
