Definitions

  • the invention relates to a method for controlling the speed limitation of an internal combustion engine in a hand-held implement according to the preamble of claim '1.
  • Portable, hand-held implements such as motorized chain saws, power cutters, hedge trimmers, brush cutters, blowers or the like are usually driven by an internal combustion engine, which must be taken on site via a starting device in operation.
  • the z. B. may be a recoil starter, the engine is placed in a start mode, d. h., the fuel supply and the combustion air supply adjusted accordingly. This can be z. B. done by the adjustment of a choke or throttle in the intake.
  • the clutch usually a centrifugal clutch, engages above an engagement speed and separates the work tool from the drive below the engagement speed.
  • a speed lock circuit is provided which keeps the instantaneous speed of the engine electronically below the engagement speed, preferably below a limit speed of the speed lock circuit forces.
  • the speed control device When the speed lock circuit is switched on, the speed control device will permanently try by controller intervention to keep the speed below the predetermined limit speed of the speed lock circuit. Therefore, after the startup phase has elapsed, the speed lock circuit must be turned off so that the user can use the entire engine speed band for work.
  • the invention has for its object to provide a method which causes without additional sensors with little technical effort to turn off a speed lock circuit.
  • the object is achieved in that a deactivation signal for switching off the speed lock circuit is generated and applied only when an operating change signal of the internal combustion engine is detected, so the operating state of the engine is changed.
  • an operation change signal is derived from the increase in the course of the instantaneous speed over time. If the user is full throttle when the speed lockout circuit is engaged, the speed increase, ie the speed swing over a time unit, will be significantly steeper than during the startup mode of the internal combustion engine. This can be done in a simple manner without additional sensors by monitoring the slope, so the mathematically first derivative of the course of the instantaneous speed over time, d. H. ⁇ n / ⁇ t occur. If there is a significantly steeper speed increase, ie if the mathematical value ⁇ n / ⁇ t is greater than a predefined threshold value, an operating change signal is generated which leads to a deactivation signal for the speed lockup circuit.
  • the deactivation signal is generated only when a predeterminable time has elapsed after the start of the internal combustion engine. This will ensure that the internal combustion engine has reached a stable operating condition before the entire speed band is released.
  • a hand-held implement 1 is shown using the example of a motor chain saw.
  • This portable, hand-held implement 1 is exemplary of other portable, hand-held implements such.

  • the saw chain 35 is driven by a not shown drive pinion and a clutch 33 from a crankshaft 13 of the engine 8.
  • the crankshaft 13 is connected via a connecting rod 11 with a piston 10 in connection, which limits a combustion chamber 22 in the cylinder 9 of the internal combustion engine 8.
  • the necessary for the operation of the engine fuel / air mixture is sucked through an intake passage 38 into the crankcase 12 of the engine 8 and ignited in the combustion chamber 22 via a spark plug 23.
  • the fuel / air mixture is from a fuel system 40, which is accommodated in an air filter box 4 of the housing 31 and fed from a fuel tank 41.
  • a throttle lever 5 for controlling the rotational speed of the engine 8 is provided on the inside; on the gas lever 5 opposite longitudinal side of the handle 2, a throttle lever lock 7 is arranged.
  • the throttle lever 5 can be operated only when the throttle lock 7 is depressed.
  • a mode selector 39 is provided which can assume operating positions such as “stop”, “operation”, “start” or the like.
  • the engine is switched to the respective corresponding operating state.
  • the internal combustion engine is started by a recoil starter 6, which - in a known manner - engages one end of the crankshaft 13 and rotates it to start the internal combustion engine 8.
  • Fig. 2 an internal combustion engine is shown in the basic structure of the engine 8 in the hand-held implement after Fig. 1 equivalent.
  • a fuel valve 17 is provided which opens into an overflow channel 20 of the two-stroke engine.
  • the volume of the crankcase 12 is connected via two symmetrically arranged overflow channels 20 and 21 with the combustion chamber 22.
  • the combustion air sucked into the crankcase 12 via an inlet 16 is conveyed into the combustion chamber 22 and, together with the fuel introduced into the overflow channel 20, is conveyed into the combustion chamber 22.
  • the mixture is ignited by the spark plug 23, wherein during the downward stroke of the piston 10, the outlet 19 opens and the combustion gases via a silencer 36 (FIGS. Fig. 1 ) dissipates.
  • the spark plug 23 is connected to an ignition device 30, which in response to the signals of an ignition module 24 and other variables spark on the spark plug 23 triggers.
  • the ignition module 24 cooperates with a rotating fan wheel 15, which is fastened on one end of the crankshaft 13 and correspondingly has circulating magnets for induction of the ignition energy in the ignition module 24.
  • a generator 14 which may also provide the energy required for ignition of the spark plug 23.
  • the alternator 14 is connected to the ignition device 30 and feeds the alternating current signals into the ignition device 30.
  • the generator 14 also provides a speed signal available, whereby the instantaneous speed n of the crankshaft 13 and the engine 8 is reported to the ignition device 30.
  • the adjoining an intake port 16 of the engine 8 opens into the crankcase 12 and is controlled by the reciprocating piston 10.
  • a position sensor 26 is arranged at the throttle valve 18.
  • a position sensor 28 can be arranged on the choke flap, which, for example, indicates an operating change, namely the operating mode "start", when the choke is closed.
  • a sensor 29 may be arranged on the mode selector 39.
  • a sensor for. B. a pressure sensor 37 may be attached.
  • the prevailing in the intake negative pressure can be directly close to the operating condition of the engine.
  • the throttle lever 5 a position sensor 25 and the throttle lock 7 to a position sensor 27, wherein both sensors 25 and 27 each emit a signal when operating the respective lever.
  • the ignition device 30 includes a speed control device 50, which is associated with a speed lock circuit 51.
  • a speed control device 50 By means of the speed control device 50, unacceptable speed states of the internal combustion engine 8 are to be avoided. So z. B. via the speed control device 50, the maximum speed of the engine 8 is set as well as an idle speed of the engine.
  • the speed lock circuit 51 specifies a limit speed n G , over which the speed should not increase, in particular at the start of the engine 8.
  • the predetermined limit speed n G is below an engagement speed of the clutch 33, which is designed in particular as a centrifugal clutch.
  • the centrifugal clutch produces a drive connection with the working tool of the implement 1 as a function of the engine speed, wherein a torque-transmitting drive connection with the crankshaft 13 is established above an engagement speed of the clutch 33.
  • a torque-transmitting drive connection with the crankshaft 13 is established above an engagement speed of the clutch 33.
  • Below the Einkuppelprintiere the drive connection is interrupted, so that the working tool is.
  • the working tool does not start uncontrollably.
  • engages the speed lock circuit whose limit speed n G with a safe distance below the Einkuppelprintiere the centrifugal clutch. This ensures that at fixed start settings, the engine 8 does not run above the limit speed.
  • the speed lock circuit 51 is only in the operation of the internal combustion engine, d. H. after completion of the starting phase of the internal combustion engine, switched off by generating a deactivation signal.
  • the deactivation signal is z. B. generated by the speed control device 50 when an operating change signal of the implement is detected, so there is a change in the operating mode of the implement.
  • the speed lock circuit 51 is initially turned on.
  • the speed lock circuit 51 thus provides the speed control device 50 with a limit speed n G.
  • the speed control device ensures that the instantaneous speed n remains below the limit speed n G.
  • the operation change signal is processed in the rotation speed control device 50 and in the rotation lock circuit 51, respectively, and in response, the rotation lock circuit 51 is turned off.
  • the user has the full speed bandwidth of the internal combustion engine available for his work.
  • the speed lock circuit 51 After the speed lock circuit 51 is turned off, it is constantly checked whether the engine is still in operation. If the user turns off the machine, the speed lock circuit 51 is immediately activated, so that at a next start of the engine, the speed lock circuit 51 limits the allowable speed back to the limit speed n G below the Einkuppelprintiere the clutch 33.
  • An operation change signal can now be derived from the increase in the instantaneous speed n over time. If the user suddenly gives full throttle, the speed increase of the instantaneous speed n, ie the speed increase over a unit of time, will be significantly steeper than idling the machine. In a simple way, the slope, ie the mathematically first derivative of the course of the instantaneous speed over time, ie .DELTA.n / .DELTA.t monitored. If there is a significantly steeper speed increase, ie if the mathematical value ⁇ n / ⁇ t is greater than a predefined threshold value, an operating change signal is generated, which leads to the deactivation signal for the speed lock circuit 51. Without a sensor, the system can detect that the user is using the machine on the job and turning off the speed lock circuit 51.
  • the operating change signal may be advantageous, in the presence of the operating change signal, to generate the deactivation signal for the rotational speed blocking circuit 51 only when a predetermined time has elapsed after the start of the internal combustion engine. In the same way, it may be expedient to generate the deactivation signal only when the operating change signal is present for a predetermined period of time. In a development of the invention, the operating change signal can also form the deactivation signal.
