Definitions

  • the invention relates to an ignition circuit for an internal combustion engine, in particular for the internal combustion engine in a hand-held implement.
  • the ignition circuit for two-stroke engines in particular for two-stroke engines in handheld tools, essentially consists of a generator for generating the necessary ignition energy and an ignition circuit, via which an ignition spark is triggered at a spark plug at predetermined crankshaft angles.
  • the spark plug together with the ignition coil, where the secondary winding of the ignition coil is located, forms a high-voltage circuit that can also be referred to as a power circuit.
  • the EP 0 727 578 A2 discloses a control device for an ignition coil in order to trigger an ignition spark in the power circuit as a function of the crankshaft angle. Depending on a magnet rotating with the crankshaft, coils generate signals that are used to activate switches in the power circuit.
  • the US 2007/0028881 A1 shows a control device for a solenoid valve which only opens a fuel supply after a predetermined number of crankshaft revolutions in order to avoid the supply of too large a quantity of fuel at the start.
  • Sensors arranged in a sensor circuit are separate from the high-voltage power circuit of the ignition circuit.
  • sensors can also be provided on the ignition circuits.
  • B. detect the crankcase pressure or the crankcase temperature and transmit the ignition circuit.
  • the JP 2005 220869 A1 shows a monitoring device for the oil level in a crankcase, in which case the monitoring device intervenes in the ignition and shuts down the engine when the oil level is inadmissible.
  • High voltage is intermittently present in the power circuit and at the spark plug, causing the ignition spark at the spark plug. If the ground connection of the power circuit is electrically broken due to a defect, uncontrolled high voltage conditions can occur which can lead to damage to the ignition circuitry.
  • the invention is based on the object of designing an ignition circuit for an internal combustion engine in such a way that undefined high-voltage states in the power circuit can be recognized and largely avoided.
  • the core concept of the invention is the coupling of the power circuit and the sensor circuit via a common line section which is connected to a reference potential and is designed as a cable and which can fail as a critical line section. If the line section z. B. interrupted by mechanical overload, both the power circuit and the sensor circuit are interrupted. While the interruption of the power circuit is not readily ascertainable, the interruption of the sensor circuit leads to an erroneous output signal at the sensor connected to the ignition circuit, e.g. B. to a maximum signal corresponding to the value of the supply voltage. This erroneous output signal from the sensor is used in the ignition circuit by the control device recognized and thus detected the interruption of the power circuit, so recognized the interruption of the high-voltage circuit. The control device generates a control signal and will take countermeasures accordingly, e.g. B. switch off the ignition, so that undefined high-voltage states are avoided.
  • the spark plug is connected to the reference potential via its attachment to the cylinder, with the power circuit being closed to the reference potential via the line section designed as a cable.
  • a voltage connection of the sensor is connected to the reference potential by a fastening on the combustion engine; the sensor circuit is closed to the reference potential via the ignition module and the line section designed as a cable.
  • the line section designed as a cable to the reference potential bridges a vibration gap between the vibration-exciting unit of the internal combustion engine and the vibration-decoupled unit of the ignition module.
  • the cable is advantageously designed as a flexible cable.
  • At least two sensors fed via the sensor circuit are provided, with the control device evaluating the sensor signals via an evaluation algorithm and intervening in the ignition depending on the evaluation.
  • the control device can, for. B. switch off when both sensors - due to the loss of the reference potential - emit a maximum signal, namely the maximum signal of their power supply.
  • the schematic in 1 Work tool 1 shown has a housing 2 on which - a guide rail 3 is held on which a saw chain 4 rotates - using the example of the motor chain saw.
  • the saw chain 4 forming a tool of the working device 1 is driven by the crankshaft 6 of an internal combustion engine 5 which essentially comprises a crankcase 7 and a cylinder 8 .
  • a piston 9 delimits a combustion chamber 10, to which a spark plug 20 is assigned.
  • the piston 9 is connected to the crankshaft 6 via a connecting rod 11; by the up and down movement of the piston 9, the crankshaft 6 is driven in rotation.
  • the internal combustion engine 5 shown is a two-stroke engine, in particular a one-cylinder two-stroke engine, the ignition of which is controlled by an ignition circuit 30 .
  • the piston 9 moves upwards, the mixture transferred into the combustion chamber 10 is ignited before top dead center is reached, in order to then, during the downward movement of the piston 9 triggered by the combustion, drive energy to the crankshaft 6 and thus the tool, in the exemplary embodiment the saw chain 4, rotating transferred to.
  • the ignition circuit 30 consists of an ignition module 31 to which the generator voltage U G of a generator 12 is supplied.
  • the generator 12 is driven directly by the crankshaft 6 and is connected to the ignition module 31 with the two connection lines 13, 14 (positive pole and negative pole).
  • the ignition module 31 supplies the spark plug 20 with a high voltage via a high-voltage line 21 in order to trigger an ignition spark.
  • a sensor arrangement 25 which consists of two sensors 17 and 18 , is also connected to the ignition module 31 .
  • One sensor 17 detects the temperature at the location of the sensor 17, i.e. the crankcase temperature, and the other sensor 18 detects the pressure in the crankcase 7.
  • the sensors 17 and 18 are expediently attached to the crankcase 7 and are connected to it via their attachment to the internal combustion engine 5 electrically connected.
  • Both sensors 17, 18 are supplied with energy from the ignition module 31 via a common voltage connection 19; the signal lines 15 and 16 of the sensors 17 and 18 lead into the ignition module 31.
  • the ignition module 31 is connected via a line section 33 to the reference potential of the internal combustion engine 5;
  • the line section 33 is preferably a cable, e.g. B. a flexible cable.
  • the implement 1 is constructed as a vibration-decoupled system, i. That is, the unit 22 containing the ignition module 31 is decoupled from the vibration-exciting unit 26, the internal combustion engine 5, via anti-vibration elements 23 and 24.
  • the high-voltage line 21, the sensor lines, namely the voltage connection 19 and the signal lines 15 and 16 as well as the connecting lines 13 and 14 and the cable forming the power section 33 are guided over the oscillating gap 27 separating the units 22 and 26 from one another.
  • the ignition module 31 consists essentially of a control device 32, which controls the ignition using predetermined parameters, and an ignition coil 34, which consists of a primary winding 36 and a secondary winding 38 in the exemplary embodiment.
  • the control device 32 and the ignition coil 34 are located within the ignition module 31, which forms a common structural unit 28.
  • the generator 12 is preferably designed as an alternator and is - depending on the number of poles and windings used - a permanent alternating signal.
  • the ignition coil 34 together with the spark plug 20, forms a right-hand in 2 Power circuit 35 shown in dashed lines.
  • power circuit 35 is constructed as follows:
  • the spark plug 20 is screwed into the cylinder 8 of the internal combustion engine 5 so that it is connected to the internal combustion engine 5 via its fastening 44 on the cylinder 8 .
  • the high-voltage line 21, which is connected to one end of the secondary winding 38, is connected to the spark plug 20.
  • the other end of the secondary winding 38 is connected to the reference potential 40 via the line section 33 designed in particular as a flexible cable.
  • the sensor arrangement 25 which consists of the two sensors 17 and 18 ( 1 ) is connected on the one hand to the ignition module 31 via the positive voltage connection 19; on the other hand, the signal lines 15 and 16 are connected to the ignition module 31, namely to the control device 32, so that the control device 32 can evaluate the sensor signals and intervene in the ignition in accordance with the output signals.
  • Sensors 17 and 18 ( 1 ) of the sensor arrangement 25 are supplied with voltage via a sensor circuit 37 .
  • the sensor circuit 37 is formed as follows: A sensor 17, 18 is electrically connected to the internal combustion engine via its attachment 42 on the internal combustion engine 5, in particular to the crankcase 7, i.e. to the reference potential 40. A sensor is also connected via the voltage connection 19 to the ignition module 31, there to the control device 32 and connected to the positive supply voltage.
  • the sensor circuit 37 is closed via the connection between the control device 32 and the reference potential 40 , this electrical connection including the line section 33 . It can be advantageous to integrate one or both signal lines 15 or 16 of the sensors 17, 18 in the sensor circuit 37; expediently, both signal lines are integrated into the sensor circuit, so that only one line, the Voltage line 19, leads to the ignition module 31.
  • the corresponding sensor signal is transmitted via the sensor circuit 37, ie the power supply to the ignition module 31, e.g. B. by modulating the sensor signal on the power supply.
  • the generator 12 When the internal combustion engine is in operation, the generator 12 provides the necessary supply voltage U G via its connection lines 13 and 14 .
  • the control device 32 controls the primary winding 36 of the ignition coil 34 according to the crankshaft angle, so that an ignition spark is triggered at the spark plug 20 just before TDC of the piston 9 and the mixture compressed in the combustion chamber 10 is ignited.
  • the piston 9 is accelerated downwards by the combustion pressure and drives the crankshaft 6 via the connecting rod 11 .
  • the combustion gases flow out through an opening outlet and the new combustible mixture is pushed over into the combustion chamber 10, which is compressed again with the upward stroke of the piston 9 and ignited again.
  • the ignition is adjusted as a function of the crankcase pressure and the crankcase temperature, for which purpose the control device 32 is connected to the sensors 17 and 18 .
  • line section 33 breaks and thus the connection to the reference potential, uncontrolled high-voltage states can occur that could damage the electronics. It is therefore provided according to the exemplary embodiment that the power circuit 35 and the sensor circuit 37 jointly use the line section 33 as a connection to the reference potential 40 .
  • the line section 33 is absolutely necessary for the function of the ignition and for dissipating the high voltage.
  • the line section 33 breaks, the power circuit 35 is open; at the same time, however, the proper voltage supply to the sensor arrangement 25, that is to say the sensors 17 and 18, also fails, since the sensor circuit 37 is also interrupted. However, if the voltage supply of the sensors 17 and 18 has no reference potential 40, their output signal rises to a maximum value. This maximum value is determined by the magnitude of the supply voltage, the positive connection of which is still connected to one voltage connection 19 of the sensors 17, 18. If control device 32 thus detects a maximum signal on both signal lines 15 and 16, it can be assumed—preferably evaluated using an algorithm and by a microprocessor—that line section 33, i.e. the electrical connection of ignition module 31 to reference potential 40, is interrupted. The control device 32 turns off the ignition device; impermissible high-voltage states cannot occur.
  • the voltage connection 19 of the sensors 17, 18 is connected directly to the reference potential 40 via a diode 39 provided as a freewheeling diode.
  • the diode 39 is switched in the reverse direction, so that the supply voltage is blocked with respect to the reference potential 40, ie the supply voltage of the sensor arrangement 25 or its sensors 17 and 18 ( 1 ) is guaranteed.
  • the voltage connection 19 of the sensor arrangement 25 or its sensors 17 and 18 ( 1 ) is also connected to the internal ground of the ignition module 31 via a suppressor diode 49 switched in the reverse direction, i.e. to the ground (negative pole) of the generator 12.
  • the suppressor diode 49 is integrated in the ignition module 31, there in particular in the control device 32.
