Abstract
In an electrically-actuated throttle device for a general-purpose engine, supply of current to the throttle motor and choke motor for moving the throttle valve and choke valve is started when cranking is detected after activation (power-up) of the electronic control unit (ECU). In other words, supply of current is not started simultaneously with activation of the ECU but is delayed until cranking is detected. Owing to this configuration, no power of the battery is consumed unnecessarily between power-up and starting of the engine. Decrease in the power supplied to the starter motor is therefore prevented, thereby improving the starting performance of the engine. In addition, even if starting of the engine is not commenced after power-up, the battery is not likely to be excessively discharged.

In addition, on intakeport 20, be connected with Carburetor 60.
Fig. 2 is the enlarged view (sectional drawing) of Carburetor 60.
As shown in Figure 2, on Carburetor 60, have integrally formed with it air-breathing road 62, motor field frame 64, Carburetor assembly 66.Solar term motor (electric actuator) 68 and choke motor (electric actuator) 70 in motor field frame 64, have been taken in.Solar term motor 68 and choke motor 70, specifically stepping motor has the stator and the rotor (output shaft) that are entwined by coil.
Air-breathing road 62, its downstream side be by thermal insulator 72 and being connected with intakeport 20, and its upstream side passes through air filter elbow 74 and is connected with not shown air filter.
In addition, dispose closure 76 on the air-breathing road 62.The running shaft 78 of closure 76 is connected solar term with on the output shaft of motor 68 by reduction gear 80.And, more also dispose chock plate 82 by upstream side at the ratio closure 76 on air-breathing road 62.The running shaft 84 of chock plate 82 is connected choke with on the output shaft of motor 70 by reduction gear 86.Like this, by motor 68 and the choke action of motor 70 of control solar term, the aperture that can regulate closure 76 and chock plate 82 respectively.In addition, solar term are respectively 0.8 (A) with motor 68 and choke with the current sinking of motor 70.
In addition, on the air-breathing road 62 between closure 76 and chock plate 82 bore of part dwindle, form Venturi tube 88 at this.
Though omitted the diagram of Carburetor assembly 66 in the drawings, it has: be connected in float chamber on the fuel pot, be connected main nozzle in the float chamber, be connected idle hole and low speed hole on the low speed fuel path that branches out from main fuel passage by main jet and main fuel passage.Main nozzle is disposed on the position in the face of Venturi tube 88, and on the other hand, idle hole and low speed hole are disposed in the face of near the position the closure 76.
When the aperture of closure 76 is big, from the main nozzle burner oil, generate mixed gas by the negative pressure that sucks air by Venturi tube 88.On the other hand, the aperture of closure 76 hour, by sucking the negative pressure of air from idle hole or low speed hole burner oil by closure 76.In addition, when chock plate 82 was closed, the air-breathing road 62 interior negative pressure that produce owing to the decline by piston 14 increased, so fuel injection amount increases, air fuel ratio increases.
In addition, mark 90 expression FS-solenoids among the figure.The valve portion (not shown) of FS-solenoid 90 is configured between float chamber and the main jet, coil (not shown) during by excitation valve be closed, block passing through of fuel thus.
Return Fig. 1 again,, be inhaled into firing chamber 18 by intakeport 20 and Aspirating valves 24 as the mixed gas of above-mentioned generation.The mixed gas that is inhaled into firing chamber 18 is burnt by igniting by not shown spark plug, and the combustion gas of Sheng Chenging are discharged to the outside of motor 10 by relief opening 22 and not shown silencing apparatus etc. thus.
In addition, near motor 10, dispose ECU (electronic control unit) 100 and the battery 102 that constitute by microcomputer.ECU100 and battery 102 are electrically connected by main switch 104.But main switch 104 is disposed at the position of operator's free operant, and when operation main switch 104, ECU100 is started.Particularly, by the operator main switch 104 is carried out making operation after, ECU100 and battery 102 conductings are accepted the supply of action current and are started.On the other hand, main switch 104 carried out opening operation after, blocked from the supply of the action current of battery 102, the action of ECU100 is stopped.In addition, the current sinking of ECU100 is 0.1 (A) at this moment.
Near main switch 104, also dispose enable switch 106 and engine speed configuration switch 108.But enable switch 106 is configured in the position of operator's free operant, and when operation start switch 106, actuating motor 44 begins action.Particularly, when by the operator enable switch 106 being carried out making operation, actuating motor 44 and battery 102 conductings are accepted the supply of action current.Actuating motor 44 is started working thus, the pto setting in motion of motor 10.In addition, but engine speed is set the position that potentiometer 108 also is configured in operator's free operant, produces the output of expression target engine speed corresponding to operator's operation.
Said temperature sensor 28, powered coil 40, pulsed coil 42 and engine speed are set the output of potentiometer 108, are imported into ECU100.The output (alternating current (a.c.)) that is input to the powered coil 40 of ECU100 is imported into the bridge circuit (not shown) of being located at ECU100 inside, carries out full wave rectifier etc. at this and is converted to direct current (d.c.).This direct current (d.c.) is fed into each several part on the motor 10 as action current.In addition, the action power of ECU100 after motor 10 startings, switches to powered coil 40 from battery 102.Therefore, when main switch 104 being carried out opening operation, till the rotation of bent axle 32 stops (that is, the generating of powered coil 40 finishes), can proceed the action of ECU100 and motor 68,70, FS-solenoid 90 etc. in motor 10 starting backs.
In addition, the output of powered coil 40 also is imported into the pulse generation circuit (not shown) of being located at ECU100 inside, and after this carried out one way rectifier, its suitable value was converted into the pulse signal as threshold level.Rotating speed by the frequency of the alternating current (a.c.) of powered coil 40 generating and bent axle 32 is proportional, thereby the pulse signal that can obtain based on the output from powered coil 40 comes the detection of engine rotating speed, and can detect pto and have or not motion.
In addition, ECU100 makes plug ignition based on the output (pulse signal) of pulsed coil 42, and the moment of plug ignition is corresponding with engine speed.ECU100 also sets the output etc. of potentiometer 108, the control solar term are regulated closure 76 and chock plate 82 with the action of motor 70 with motor 68 and choke aperture based on temperature transducer 28 and engine speed.That is, constitute electrically-actuated throttle device with motor 68, choke with motor 70 and ECU100 etc. by solar term, the rotating speed of motor 10 is regulated by this electrically-actuated throttle device.
In addition, the pulse signal that ECU100 obtains based on the output from powered coil 40, the initialization process of the aperture of execution closure 76 and chock plate 82 (particularly, by make solar term electricity consumption motivation 68 and choke with the position alignment of the rotor of motor 70 at initial position, thereby make the aperture of each valve be aligned to processing at initial opening).
Fig. 3 is the flow chart of initialization process of the aperture of expression closure 76 and chock plate 82.Illustrated program is to carry out with the cycle (for example every 10msec) of regulation.
Below, the processing of Fig. 3 flow chart is described, at first, in S10, judge whether initialization complement mark place value (initial value is 0) is 1.When negating, enter S12 in the judged result of S10, judge whether to detect the motion of pto, in other words, judged whether to make the pto setting in motion by operator's operation start switch 106, actuating motor 44 actions.This processing is based on and has or not the pulse signal that obtains from the output of powered coil 40 to carry out.
Judged result at S12 is when affirming (pulse signal is arranged), to enter S14, carries out the aperture initialization of closure 76.Particularly, beginning with motor 68 energisings, makes closure 76 be standard-sized sheet to solar term, and stepping position at this moment is stored among the RAM (not shown) of ECU100 as initial position.Then, enter S16, carry out the aperture initialization of chock plate 82 equally.Particularly, beginning with motor 70 energisings, makes chock plate 82 be standard-sized sheet to choke, and stepping position at this moment is stored among the RAM (not shown) of ECU100 as initial position.
Enter S18 then, establishing initialization complement mark place value is 1.Therefore, after the initialization of the aperture of each valve is finished, the 2nd time and after program when carrying out, the judged result of S10 is for certainly, S12 is then skipped to the processing of S18.
In addition, when negating, also skip the processing of back in the judged result of S12.Therefore, even after the ECU100 starting,, just can not begin to solar term motor 68 and choke motor 70 energisings as long as pto does not have setting in motion.
Like this, the electrically-actuated throttle device of the general-purpose engine of the 1st mode of execution of the present invention, in ECU100 starting back (after connecting power supply), and when detecting the motion of pto, beginning is switched on motor 70 with motor 68 and choke to solar term, and closure 76 and chock plate 82 opened and closed, in other words, owing to be such formation, promptly, not that starting with ECU100 begins simultaneously to each motor energising, but till the motion that detects pto, be in holding state, so during (till the pto setting in motion) till 10 the starting from the engaging means power supply to motor, the electric power of consuming cells 102 necessarily.Therefore, the minimizing of the electric power of ato unit 44 can be prevented to supply to, the startability of motor 10 can be improved.In addition, even after connecting power supply and during motor 10 unstarts (pto is setting in motion not), also be difficult to use up the electric power of battery.
Above-mentioned effect is specifically described, and as mentioned above, solar term all are 0.8/ (A) with motor 68 and choke with the current sinking of motor 70, and the current sinking of ECU100 is 0.1 (A).Therefore, as prior art, and connect power supply and begin simultaneously when each motor energising, during till the pto motion continuous consumption add up to the electric current of 1.7 (A).Relative therewith, the application's current sinking only is 0.1 few (A) of ECU100, the battery consumption amount can be controlled at bottom line.
In addition, the switching of performed closure 76 and chock plate 82 is handled when detecting the motion of pto, particularly be the initialization process that the aperture of each valve is adjusted to initial opening, so can precision make the valve opening after the engine start consistent well with the target aperture.
In addition, in the 1st mode of execution, though these two opens and closes to closure 76 and chock plate 82 by electric actuator, the application's structure also is applicable to the electrically-actuated throttle device that either party is is wherein opened and closed by electric actuator.Its meaning shows as " closure and chock plate at least any " in claims.
Below, the electrically-actuated throttle device of the general-purpose engine of the 2nd mode of execution of the present invention is described.
The 2nd mode of execution relates to the aperture control of chock plate 82.
Fig. 4 is the flow chart of its processing of expression.Illustrated program is identical with the 1st mode of execution, after the ECU100 starting, is carried out by ECU100.
Below, the processing of Fig. 4 flow chart is described, at first, in S100, judge whether main switch 104 is carried out making operation, that is, judge ECU100 whether with battery 102 conductings.ECU100, owing to the supply of accepting action current in motor 10 prestarts and battery 102 conductings, usually in the judged result of S100 for certainly.Enter S102 then, judge whether to detect the motion of pto, in other words, judge whether to make actuating motor 44 move the pto setting in motion by operator's operation start switch 106.This processing is based on to have or not and obtains pulse signal from the output of powered coil 40 and carry out.
During for (pulse signal is arranged) certainly, enter S104 in the judged result of S102, based on the initial opening of output (temperature of motor 10) the computing chock plate 82 of temperature transducer 28.Initial opening be the temperature of motor 10 when low more its opening value big more.In addition, in the judged result of S100 or S102 when negating, carry out once more above each handle.
Then, enter S106, the control choke is with the action of motor 70, and the aperture of chock plate 82 is adjusted to described initial opening, enters S108 afterwards, judges whether the starting of motor 10 is finished.Whether the processing of S108 is to have reached according to the rotating speed of judging motor 10 to break out rotating speed (for example 1000rpm) fully and carry out.
When negating, carry out the processing of S104 and S106 in the judged result of S108 once more, on the other hand, for certainly the time, enter S110 in the judged result of S108, computing carries out the transition to the time of standard-sized sheet and the target aperture of chock plate 82.As shown in Figure 5, the time that what is called carries out the transition to standard-sized sheet is meant that the aperture (choke aperture) of chock plate 82 carries out the transition to standard-sized sheet aperture (for example 72 °) the needed time from initial opening (present aperture), and it is based on the output of temperature transducer 28 and determine.Particularly, for the temperature of motor 10 is low more, then standard-sized sheet is long more transient time.And in the determined time that carries out the transition to standard-sized sheet, the value of this of target aperture is determined, so that chock plate 82 is little by little driven valve from initial opening to standard-sized sheet.
Then, enter S112, the control choke is adjusted to described target aperture with the action of motor 70 with the aperture of chock plate 82.Enter S114 then, judge whether main switch 104 is disconnected operation, that is, judge whether the conducting of ECU100 and battery 102 is blocked.When negating, carry out the processing of S110 and S112 in the judged result of S114 once more.In addition, motor 10 is during by abundant preheating, and the time that carries out the transition to standard-sized sheet is confirmed as zero, so the target aperture is confirmed as standard-sized sheet.
On the other hand, for certainly the time, that is, when main switch 104 is disconnected operation, enter S116 in the judged result of S114, the control choke with the action of motor 70 so that the aperture of chock plate 82 is a full cut-off.In addition, when main switch 104 is disconnected operation, in not shown program? by making ground connection between firing circuit and the spark coil (all not shown), light a fire and cut off, and, by to FS-solenoid 90 energising, and cut off fuel oil, motor 10 is stopped.In addition, the control solar term use the action of motor 68 so that closure 76 is a standard-sized sheet.
In addition, though main switch 104 is disconnected operation, the conducting of ECU100 and battery 102 is just blocked, as mentioned above, rotation up to bent axle 32 stops still can to continue the action of ECU100 and motor 68,70, FS-solenoid 90 etc. till (generating of powered coil 40 finishes).
