Description

M273631 IV. Creation Description α). [Technical Field to which the New Type belongs] This creation relates to a capacitor discharge ignition device for igniting a spark plug of a locomotive. The purpose is to provide a capacitor discharge ignition that can quickly ignite a spark plug using a simple structure. Device. [Previous technology] According to the press, most of today's locomotives use capacitive discharge electronic igniters, commonly called CDI (Capaci ty Di scha rge Ignition), which uses the voltage of the battery (generator) to charge the capacitor in the controller When the ignition signal is transmitted, the 0 capacitor is discharged to the primary coil of the ignition coil. This sudden increase in voltage causes the primary current to expand the coil magnetic field, and causes the secondary coil to induce high voltage electricity 'after the south piezoelectric is delivered to the Martian base'. Before the occurrence of cremation, there was a gap in the spark plug, so it was a non-conductor, but when the voltage reached a certain value, the gap in the spark plug suddenly became a conductor and sparks crossed the gap. This voltage value is called "jump Firing Voltage ”〇 And, the general engine tripping voltage is about 1 0 0 0 ~ 2 0 0 0 V, so there is a structure in the house that can quickly charge the capacitor, as shown in the first picture As shown, the primary coil 11 of the coil group 10 is connected to the voltage input terminal A, and the other end of the primary coil 11 is connected to a control on_off 2 0, which is controlled by a signal PWM (pulse-width modulation signal) output by the control 30 is turned on or open circuit, the secondary winding of the coil group 1 ◦ 12-- end connected with a capacitor 40, the other end is shaped

Page 5 M273631 4. Creation instructions (2) Grounded, capacitor 40 is connected to ignition coil 60, and ignition coil 60 is connected to spark plug 70, which is composed of a primary coil 6 1 and secondary coil 62. When in use, a specific signal is generated by the signal generator 30 to turn on the control switch 20. When the voltage input terminal A and the primary coil 11 are turned on, the primary coil 11 is charged, and the secondary coil 12 induces high voltage and The high-voltage electricity is transmitted to the capacitor 40 to store electricity. When the voltage reaches a certain value, an ignition control signal 80 controls an ignition switch 8 1 to discharge the electric container 40 to the primary coil 6 of the ignition coil 60. 1, this sudden increase in voltage causes the primary current to expand the coil magnetic field, and causes the secondary coil 2 to induce high voltage, which in turn causes the gap between the two electrodes of the Mars plug 7 1 to suddenly become a conductor and sparks to cross the gap, thereby making the Mars plug Ignition; because its voltage needs to be more than 1 000 0 V, if the capacitor 40 needs to be quickly stored, the number of windings of the primary coil 11 and the secondary coil 1 2 of the coil group 10 is increased to shorten the storage time, but it is easy to cause The coil group 10 has a large volume due to the excessive number of coils, which not only reduces the cost-effectiveness and reduces the competitiveness, but also increases the heat generation rate when the power is turned on. [New content] This creation "Capacitance Discharge Ignition Device" includes at least: a wire_circle, a signal generator, a control switch, a power storage unit, an ignition coil, and a spark plug. It generates a specific signal through the signal generator to enable control. When the switch is turned on, the voltage input terminal and the coil are turned on to charge the coil, and when the control switch is turned off, the voltage input terminal, the coil, the power storage unit and the ignition wire are charged.

Page 6 M273631 3. Creation instructions (3) The coil is turned on, and the coil also outputs a large voltage to the power storage unit. The power storage unit transmits the large voltage to the primary coil, and the secondary coil induces this large voltage to ignite the spark plug. . [Implementation] In order to enable your review committee to operate in an overall manner, we have created a "capacitor discharge point contains a coil 50, a switch 2 0, a power storage unit | mainly), an ignition coil 6 The ignition control signal 80 is controlled by the voltage signal generator 30, which is connected to the WM (Pulse Width Modulation Signal) circuit; the control switch 20 is connected to ground at one end, and the control switch 20 (insulated brake double Carrier transistor) connected to 0, and can be connected to capacitor 40 at the ignition interval, consisting of; as for the Mars plug 62, which is connected by two electrodes 7 ignition control signal 8 0 can be SCR or The IGBT switch clearly states that the result of this creation is as follows: "Fire device", such as the composition of the signal generator of this embodiment, and the unit (0, the input coil to control and wire can constitute the first power of 7 0 1-phase ignition, one of the spark plug ignition switch 8 terminal A is connected to the control 50, the control switch circle 50 is connected to M0SFET, capacitor 4 current storage; point-level coil 6 1, and a specific gap from the ignition line Off 8 1, and capacitor 4 2 Figure 3 0 to electricity 7 0 1; The switch is used for 2 0, and the electric crystal 0, hot wire and the secondary circle are shown at the 0 phase of this point, to a control container 4 0, And one of them: 2 0; when a P is turned on or off, the shape or IGBT is connected to the coil 5 turns 6 0, the secondary coil 6 is connected to the secondary coil by the fire switch 8, and

Generate a PWM (pulse width voltage input terminal A and the coil switch 20 open circuit, electricity 0 and the ignition coil 60 lead to the container 40, the capacitor makes the secondary coil 62 induction to a square wave signal, which can control the switch At 0 at 0, the charging / discharging is continued. When the voltage reaches a certain value, the ignition switch 80 is turned on. The primary coil 6 1 of 0 has a large coil magnetic field, and the gap between the two electrodes 7 1 of the secondary star plug is used to make the spark plug coil. The simple structure, that is, the spark plug can be quickly ignited to cause a large-capacity, heat-generating, capacitive discharge ignition: However, the above implementation says M273631 g, creation instructions (4) The ignition control signal can be transmitted to the capacitor 4 based on, That is, the signal generator 30 changes the modulation signal. When the control switch 20 is turned on, 50 turns on and the coil 50 is charged. When the voltage control input A, the coil 50, and the capacitor 4 are turned on, the coil 50 also outputs a voltage to Electricity 40 transmits this voltage to the primary coil 6 1. As PWM (pulse width modulation signal) can continue to send 0N / 〇FF signal, in the state of repeated on / off, and the coil 5 is charged, and then the capacitor 40 is quickly charged, when the ignition control signal is 80 The input signal causes the capacitor 40 to discharge to the ignition coil 6. This sudden increase in voltage causes the primary current step-up coil 62 to induce high-voltage electricity, so that the fire gap will suddenly become a conductor and a spark will be generated over 70 to ignite. It is worth mentioning that the use of this method can shorten the storage time of the capacitor 40, and can eliminate the disadvantages of using the coil group 10, etc. As mentioned above, this creation provides a better device to file a new patent application according to law
