Nine, the invention is: [Technical Field of the Invention] The present invention relates to a fuel injection of a fuel injection module equipped with a plunger that is sucked back and forth to attract and pressurize fuel. In particular, in the various operating states of the engine, the technique of stabilizing the fuel injection state and preventing the slip from being smoothly generated can be often achieved. [Prior Art] An electronically controlled fuel injection device that calculates a fuel supply amount and performs fuel injection in response to the number of revolutions of the engine and the load, has conventionally proposed a fuel injection module having the following configuration. That is, the solenoid (s) is energized by the driving signal supplied from the control unit, and the plunger (four) is sprayed into the current by the electromagnetic force generated by the solenoid coil. The gas difference f (intake deg), :t :=) is attracted to the next fuel when it is pressed back by the spring (for example, referring to the patent using the fuel injection device of the fuel injection module thus constructed, the fuel pump and the adjustment H In order to carry out the pressurization of the fuel and the method of injecting the pressurized fuel into the second, it is possible to achieve a smaller number of constituents. In addition, it can be used only for the two periods of the pressurized county and the moving (four) material stroke. In the middle, the Μ drive signal can be used to open the solenoid coil, and there is no need to electrify during the suction stroke of attracting fuel, so that the average power consumption is reduced. Therefore, the system is extremely suitable for rural power: low battery capacity Small two wheel * Motor or another aspect, in the conventional fuel injection device, has a return (four) step (4) with the engine 318495 6 1308193. The time is scheduled to be _ and not the same as the engine rotation, the warehouse / t, the door ^Scheduled, by... Dynamic injection of Ding fuel injection., Shi private? When using the above fuel injection module as a jetting injection, when the suction temperature or engine temperature is low, the engine is negative. The amount of charge in the skirting pool is small, so that the x and the private batch of Xia - the amount of power in the pair of solenoid coils is small, the long way to adjust. Another move to the "interval valve" (throttle -vaive), in order to accelerate the throttle, the acceleration can be smoothly accelerated, and the fuel is supplied to the intake manifold. If the non-synchronized mouth injection:::order = will be in the unfinished fuel = suction (10), ^ 'can not correctly control the fuel consumption two = turn::, non-synchronous spray two::: sequence 3 system proposed the following Technology, that is, 'injection stroke, is the pressure stroke of the step injection or the injection of the nozzle After the interval, the injection time is added to the synchronization timing overlap with the synchronization nozzle ===, and the start timing of the start of the synchronous injection is delayed to the same as the asynchronous injection, thereby enabling the synchronization nozzle to be The delay of the door attracting the end of the trip is in the literature 2). The shot and the non-synchronized shot are simultaneously present. (9) As for the reference [Patent Document 1], the Japanese version of the w22(10) bulletin 318495 7 1308193 *[发it献2]曰本特Open the secret of her bulletin--(the subject of the invention to be solved) "2; and, in the prior art, - use both synchronous jet and non-synchronized mouth-shot synchronization timing and drive of the firing module' Yahoo has set any restrictions on the existence of the supply to the fuel spray, so there are currently the problems indicated in the following 4(4) to (D). As described above, when the synchronous injection is performed, the degree of the dish is low, the engine load is large, and the amount of charge of the battery is small, the rotation time of the number is delayed. The control unit is used to drive the signal. The line is tuned, but as shown in Figure 11 (4), the output time T1 of the drive signal makes the driver's door 沾 沾 4, and the cooking limit is extremely long, and the JU 3 is spaced apart from each other. H f is hereinafter referred to as the fuel absorption time 2 2) # 4_ n 士 and (4) and the time (as at (4) is as shown in Fig. 11 (8), and the suction stroke of the igniting is not pressurized, the injection stroke (The U _ symbol shifts down to the portion of the next charge X that causes the shortage of the fuel injection amount), and thus _=: avoids this deficiency', for example, as shown in Fig. 11(c), if desired Then: After the T1, the fuel suction time is often ensured Τ2, and the J _ produces the following new problem. That is, the current 4-cycle type of enthalpy is set to tc, then the second from the same engine.

Then, with the passage of time, (-2)-2 · TC-difference knife gradually accumulates, making the fuel injection whitening 7 -51 ^ ^ 4〇έ,. The inch d is gradually delayed, and it will cause the fuel injection line of the Liuhuhe shooting group to be in the W part even if the material is transferred to the compression stroke. =The situation of the two Ding (the U figure (4) -.,,,,,,,,,,,,,,,,,,,,,,

(8) In addition, In the above-described Patent Document 2, when the delay stroke of the synchronous injection is superimposed on the suction stroke of the synchronous injection, the delay timing of the delayed injection is delayed until the delay processing of the synchronous injection is terminated. When the stroke or the injection stroke of the synchronous injection of the next sentence is overlapped (for example, refer to FIG. 12 (a), (b)), the injection time of the asynchronous injection is added to the injection time of the next injection (refer to Figure 12 ( 〇).

If the engine's intake stroke ends and the compression stroke is moved, the fuel injection module is also made. The fuel injection stroke continues to advance, and the suction stroke of the fuel injection module will not exist for the bear (the portion indicated by the symbol z of the figure (c)). As a result, uneven fuel injection is generated in each of the $burning strokes, resulting in a lack of engine. π 卜 only two, especially as shown in Fig. 13 (a), (8), in the case of frequent injection of asynchronous nozzles for synchronous injection, as shown in the 13 ® (e), each engine burns The frequency at which the fuel injection amount is unevenly generated during the stroke also increases (the portion indicated by the sign Z in Fig. c), and the engine rotation is extremely unsmooth. The present invention is for solving the above problems, and the researcher uses the fuel injection module to perform the fuel injection when the fuel is discharged, and the second is set to a certain limit, thereby maintaining stable fuel in various operating states of the bow engine. The fuel injection device can be effectively prevented from being generated by the engine rotation. (The means to solve the problem), to achieve the above purpose 'has to have a jetting module by the back and forth movement of the plunger... and the drive for driving the plunger according to the operation of the engine ^ ^ , The fuel injection molding of the present invention is controlled by the above-described fuel injection molding, and the fuel injection (four) of the present invention is controlled by the following structure.

The nozzle 84, the nozzle hole 85 318495 13 1308193 = the injection port δ6:, and the nozzle is injected into the intake manifold 15. This fuel injection is the fuel injection time. Further, the above-mentioned benefit time _·=Τ11 and the total time of the fuel injection time claws (=丁_2), and the output time m for the production of the drive signal are referred to Fig. 3). $ T1 2 passes the output time π of the driving signal supplied from the control unit 10, and stops the training of the solenoid after the solenoid is printed, so that when the column money is π, 'there is a return to the column by the unillustrated column' When the base 81 returns to the original position and slams upward, the time required for the pump 87 to be sucked into the cylinder 82 is changed from the fuel tank 11 via the feed. *., 枓 suction bow ί in synchronous injection (10): fuel suction time Τ 2 phase injection is basically the same. When the yoke is synchronized, the control unit 1G is supplied to the fuel injection module to determine the decision.

Further, in the case where the degree of opening of the throttle valve 3 is increased by the degree of entanglement, the non-synchronized projection is performed for the acceleration. In '+, in order to make the reciprocating interval' the same as in the synchronous injection, for the basic injection time, the door/inch ;; =! time τ] 2' after the output plus the invalid nozzle shot == when there is output · TmTI2 ) The drive signal. Chuanzhi 318495 14 1308193 The round-out time is called the drive signal of the synchronous drive k-buts synchronous injection. The output time of the signal is called non-input: the drive when the non-synchronous injection is entered. The symbol is used to show the synchronous drive = r Time, in order to distinguish between the two, is time. (4) Inter-station is represented by the symbol Τ3. In this embodiment, the synchronous driving time T1 at ## is not the same as that of the engine. Operation: = asynchronous drive when the nozzle is fired. It is unconditionally set for two time Π, Τ 3^ for a long time. Heart plus - set limits. In this regard, the following will be described:: The engine is based on the _ degree sensing number output to the fuel injection mode = axis rotation synchronization and the drive is signaled to the engine, in this embodiment 1, the second ratio is 'private仃(4)' Therefore, for every 2 revolutions of the crankshaft, the output has a synchronous drive time τ. The drive signal is tied to each of the above...,: <5 mirror. That is, the heart and the engine are output in the TG, and the TG is injected from the fuel injection module 8 in the period of 2 Κ. If the fuel injection interval is set to 2TC, then At the time of output at this time, the intervening T1 is subjected to the following limitation', and the maximum driving time which is the upper limit of the elapsed time of the drive signal is set. T1^ 2 · TC-T2 (1) 疒5, that is, when the formula (1) is satisfied, as shown in Fig. 4(a), the fuel injection module 8 is added during the second injection. The sum η + T2 of the time required for each τ process of pressing, spraying, and attracting is limited to not exceed the γ period from the start of the intake stroke of 318495 15 1308193 to the next γ. As a result, it is often ensured that the fuel suction time is Τ2ς='2 in Fig. 4 (8), and the pressure stroke of group 8 is heavy, θ /, 卜 - human The fuel injection mold should be sprayed once (4) 4 '", and the sputum module 8 can surely attract the engine that is not smooth. The shape is caused by insufficient fuel injection. =:: Show: Example". The figure (4) is a timing chart which is shown together with the example shown in Fig. 8 as a comparative example. That is, there is no limitation in the synchronous driving time Ti in the two cases, so as shown in Fig. 8 (4) Synchronous driving time T1 is extremely long', as shown in Fig. 8(b), it will move to the next-time inking and jet marking at the time of attraction of the fuel of 20% (the figure of Figure 8 (8) ^ ^The part shown), resulting in insufficient fuel injection amount, or the sum of the synchronous driving time T1 and the fuel suction time T2 and the T1+T2 ratio = the base reference period 2·Tc, resulting in the movement of the engine even if the intake stroke ends At the time of the compression stroke, the fuel injection of the fuel injection module 8 is also continued (the portion indicated by the symbol γ of Fig. 8(c)), and the fuel injection is generated in each engine combustion stroke. In contrast, in the present embodiment, as shown in FIG. 8(d), the synchronous driving time T1 satisfies the condition of the formula (1), and thus, as shown in FIG. (e) does not allow the fuel injection module 8 to reliably attract the next injection. And prevent the engine from rotating due to insufficient fuel injection. 16 318495 1308193. If the celebrity meets the condition of the formula (1), the fuel injection time will not exceed the limit due to the fuel injection time Τ12. Value, therefore, although there is still a limit to the correction of the corresponding atmospheric temperature, intake temperature, engine temperature, etc., there is no problem under the continuous rotation of the engine 1, and fuel injection per one person The same amount can also make the engine torque change disappear, so it is beneficial to prevent the engine from slipping smoothly. Ifn '; 4 stroke type engine 1, inhalation - compression ~ expansion - each stroke of the gas is The two rotations of the crankshaft (72 〇.) are completed, but the detection output of the shaft angle sensor 7 is two times per crankshaft revolution, so 'only according to the detection of the crank angle sensor 7, the helmet The method discriminates each stroke. Therefore, at this time, it is possible to use #h^", and the detection output is used to discriminate each of the walking bodies; 7 the measurement output of the force sensor 5 is determined until the detection of the suction (four) force sensor 5 to During the period, It is difficult to specify individual trips. In the case of the simultaneous injection injection, the period until the respective lines _ 引擎 of the engine 1 can be discriminated can be synchronized at each of the reservations.检测 The detection output of the axis sensor 7 is every 36f). ,,,, that is, synchronous injection is not every 720. , and then = this: that is, in the half of each engine's reference period, the same time, the fuel injection interval is set to TC, then the Danbu driving time T1 is the same as K.

Therefore, if the first to attract time Τ2 is not suitable for the engine, for example, when the engine is accelerated, the pressure stroke of the fuel H k ^ fuel injection module 8 can be often ensured. 0, the fuel injection module 8 can surely prevent the engine from rotating smoothly due to the fact that the Ding red weight is due to the material. The fuel burning can be known from the example shown in the ninth circle. The figure is an example of the operation of the control signal 318495 20 1308193, which is said to have been supplied with the drive signal of the U-shaped diagram, as shown in Fig. 5, in the case of the simultaneous use of the synchronous nozzle and the non-synchronous injection.

In addition, the 1G map is in this embodiment, and the synchronous injection = two spray S' corresponds to the slave control unit. Other examples of the fuel of the driving signal supplied, and the conventional example shown in Fig. 13 is a timing chart which is displayed in comparison with the parent 1 +. As shown in Fig. 10 (a) and (b), the synchronous nozzle is prepared. When the asynchronous injection is frequently performed, in the comparative example, the unevenness of the fuel injection amount generated in each of the strokes becomes (four) the portion indicated by the symbol z of the frequency 103⁄4 (c), and (4) the engine In contrast, if the fourth embodiment satisfies the item (4), 318, 495, and 21, as shown in Fig. 10 (d) and (e), the engine reference period is 2. TC Indeed, the second injection module 8 can prevent the fuel injection amount of the engine from being uneven. The fuel to be injected, and as described above, In the first aspect, the respective pieces (1) to (4) of the above formulas (1) to (4) are used to satisfy the simultaneous injection and the force: in the various operating states of the engine 1, It can be shot when m is sprayed. As a result, a stable fuel can be maintained, and the injection = the generation of the fuel injection engine 1 is not light. The material is effectively prevented from being introduced to the above embodiment! In the case where the engine injection is described as an example, the engine 1 may be used for combustion; the present invention is also defined herein: a case where a private engine performs fuel injection.
