Abstract

To prevent generation of fog of fuel to a spark plug by unburnt fuel by a shortage of torque at kicking start. A crank reference position detecting part 25 determines whether or not a crank pulser signal corresponds to the upper dead center of an intake stroke. A crank angle speed detecting part 26 detects a crank angle speed when the crank pulser signal is of the intake stroke. The crank angle speed is represented by time of a stage. The time of the stage is inputted to a comparing part 27, and is compared with judging criterion time Tref. When the crank angle speed is larger than an expected value, the duty of a fuel injection valve is calculated. When the crank angle speed is smaller than the expected value, the duty for indicating a fuel injection quantity is set to zero.

Embodiment
Below present invention will be described in detail with reference to the accompanying desirable embodiment.Fig. 2 is the automatic double wheel vehicle main structure figure of band pedal-start device that comprises the fuel injection control system of one embodiment of the invention.Though not shown at this, this automatic double wheel vehicle has by the fuel supply system that constitutes with same hardware shown in Figure 7.
On engine crankshaft 1, be connected with the pedal (foot treadle) 2 that is used for foot pedal starting by foot pedal starting gear and ratchet (the two is all not shown).The plectane 3 that is provided with a plurality of teeth (timer magnetic core) in periphery is combined on the bent axle 1.Predetermined angular (for example 30 degree) configuration at interval of timer magnetic core.
Speed probe 4 for example is made of Photo Interrupter, detects described timer magnetic core and crank shaft angle signal 5 is outputed to Fi-ECU (fuel injection control system) 6.Crank shaft angle signal 5 is signals of crank shaft angle of predetermined angular of representing the configuration space of each corresponding timer magnetic core, according to this crank shaft angle signal 5, calculates the rotating speed of motor with Fi-ECU6.
And then, the special position on the circumference of plectane 3, promptly (for example imbedding) magnet is installed in the position of corresponding top dead center.The CRANK PULSES sensor 7 that is made of the magnetic pick-up sensor detects this magnet and CRANK PULSES signal 9 is outputed to Fi-ECU6.The drive signal 10 that oil sprayer 8 leaves the valve load by expression drives, the corresponding fuel injection amount of being determined by Fi-ECU6 of this load.Below further comment the action of Fi-ECU6.
Fig. 3, Fig. 4 are the ignition timing figure of fuel injection control.At this, crank shaft angle 30 metrics are decided to be one section, 360 metrics that motor is turned around are decided to be 12 sections.Thereby a circulation of the motor that will be made of air-breathing, compression, burning, exhaust is defined as 24 sections of 720 degree.The numerical table of crank shaft angle signal 5 shows hop count, and CRANK PULSES signal 9 motors whenever turn around output once.
In Fig. 3, after moment t1 uses foot treadle 2 to begin starting,, the supply voltage of Fi-ECU6 is risen by the generator for electricity generation that combines with bent axle 1.Then, begin resetting of Fi-ECU6 and initialization at moment t2.This reset and initialization after the moment, t3 finished, driving fuel supply pump (FFP) 14.Detect CRANK PULSES signal 9 at moment t4, detect the section that is right after thereafter, i.e. the 17th section pulse width (time).At moment t5, judge whether burner oil based on the 17th section pulse width.When wanting burner oil according to this judgement, the computing fuel emitted dose drives oil sprayer (INJ) 8 at moment t6.When burner oil not, do not calculate yet burner oil not of fuel injection amount.
Fig. 5 is that fuel sprays the judgment processing flow chart.This processing is carried out when detecting the CRANK PULSES signal at every turn.Whether definite, whether detect suction stroke promptly differentiate the CRANK PULSES signal 9 that detects in combustion stroke and suction stroke in the middle of at step S1 if differentiating crank reference position.This for example can judge by the sucking pipe negative pressure Pb when detecting CRANK PULSES signal 9.At step S2, judge whether present section is the 18th section.If crank reference position determines, then can determine immediately following 17 sections of thereafter Duan Weidi, so 18 sections of Duan Weidi again.
If step S2 is sure, then judge at step S3 whether pulse width (time) T17 of corresponding the 17th section crank shaft angle signal grows than the judgment standard time T ref that is used for the fuel shutoff supply.Fiducial time, Tref was used to judge that whether bent axle is can make piston cross the reference value of enough speed rotations of compression top center.
, judge angular velocity of crankshaft little (low speed rotation), and enter step S4 when fiducial time, Tref was long in the pulse width T 17 of crank shaft angle signal.In addition the pulse width T 17 of crank shaft angle signal than fiducial time Tref in short-term, judge angular velocity of crankshaft big (high speed rotating), when judging that piston surpasses compression top center, enter step S5.At step S4, setting stops burner oil sign Ffc (=1).At step S5, will stop burner oil sign Ffc zero clearing (=0).At step S6, carry out burner oil program based on the calculating of fuel injection amount and result's thereof burner oil.
Fig. 6 is the burner oil program (detail flowchart of step 6).At step S61, differentiation stops burner oil sign Ffc.When being " zero ", this sign Ffc enters step S62, computing fuel emitted dose.Fuel injection amount calculates based on engine parameters such as throttle valve opening, engine speed, engine water temperatures, represents with the valve load of opening of oil sprayer 8.At step S63, drive oil sprayer 8 fuelings according to the fuel injection amount that calculates.When fuel sprays sign Ffc and be " 1 ", enter step S64, be that " zero " enters step S63 with the valve load setting of opening of oil sprayer 8.
Fig. 1 is the block diagram of the major component function of expression Fi-ECU6.Crank reference position detecting part 25 response CRANK PULSES signals carry out stroke and judge.Stroke for example judge can by sucking pipe negative pressure Pb whether the negative pressure of corresponding suction stroke judge.This is because bigger than other strokes at suction stroke sucking pipe negative pressure Pb.If detect the CRANK PULSES signal in suction stroke, then can be by angular velocity of crankshaft detection unit 26 based on crank shaft angle input angular velocity of crankshaft.Angular velocity of crankshaft is by the pulse width of crank shaft angle signal, i.e. the time of a section after the crank shaft angle reference position decision is represented.When angular velocity of crankshaft was big, the time of a section was short.The time T 17 of a section of signature song axis angular rate is input to comparing section 27, compares with judgment standard time T Ref.Result relatively is input to fuel injection amount calculating part 28.When angular velocity of crankshaft is bigger than predetermined value, press engine parameter computing fuel emitted dose, calculate specifically and open the valve load.In addition, if judge angular velocity of crankshaft, then fuel injection amount (load) is made as " zero " than predetermined value hour.That calculate or be set at the fuel injection amount of " zero ", promptly open valve load and be input to oil sprayer drive portion 29.Oil sprayer drive portion 29 drives oil sprayer 8 according to the valve load of opening of input.
In addition,, stop burner oil for " zero ", also can not make fuel injection amount be entirely " zero ", spray the degree that stops as long as making fuel injection amount reduce to fuel in fact by making out the valve load at the foregoing description.
More than be illustrated according to the present invention being applied in the example of automatic double wheel vehicle with the engine fuel injection control gear.But the invention is not restricted to this embodiment,, for example suitable equally on the generator of engine-driven at automatic double wheel vehicle with the motor that starts with manpower with motor in addition.
First to fourth aspect according to the present invention, when judging the abundant angular velocity of crankshaft that is not obtained making piston cross compression top center by the manpower turning crankshaft, stops burner oil.Thereby, can prevent that fuel from covering spark plug, improves starting performance.
Particularly according to third aspect present invention, when supplying with and stopping fueling, owing to available same control function driving fuel injection valve, so control is simple.
In addition, according to fourth aspect present invention, the waste of the electric power that uses in the time of can saving burner oil can utilize sufficient fuel pressure in the starting next time after starting failure, pilots engine reliably.
