However, automobile engines that use energy storage ignition devices generally suffer from a low conversion of ignition energy (referring to the conversion of electrical energy into chemical energy). Because during the ignition process of the existing energy storage type ignition device, the air insulation layer between the spark plug electrodes cannot be recovered immediately after breakdown, and the secondary energy of the ignition coil is discharged under a voltage drop condition that is several times the breakdown voltage, As a result, the conversion energy is greatly reduced, and the stored energy cannot be fully utilized. In addition, because the air insulation layer between the spark plug electrodes cannot be restored immediately after breakdown, the direction of the current is unchanged, the direction of the magnetic field lines is also unchanged, and the effect of the magnetic field is greatly affected. Weakening; in order to make the physicochemical reaction have combustion conditions, the prior art adopted measures to continue to increase energy storage energy, which resulted in a high-energy igniter. However, this existing high-energy ignition ^ Problem, but still can not fundamentally solve the problem of engine combustion speed. Disclosure of the present invention

The frequency characteristics are integrated, which overcomes the above defects of the prior art. Therefore, the object of the present invention is to provide a continuous breakdown engine ignition device, which is based on the existing energy storage type ignition device, and adds a high-frequency generator to make full use of the stored energy to isolate the All light discharge energy is converted into breakdown discharge form, which improves discharge energy and increases energy conversion efficiency, thereby greatly improving combustion efficiency.

图 2是本发明的连续击穿放电的发动机点火装置的电路原理 图。它由储能装置 I和本发明的高频发生装置 Π构成。其中高频发 生装置由集成块 UA2 (CA555)、三极管 Q17、Q16、二极管 D7、电容 C13和电阻 R36、R37、R38、R39、R40、R41和 R42构成，其中集成块 UA2的 3脚经电阻 R36与储能点火控制电路的输出端 Y连接，集 成块 UA2的 2脚与 6脚相连接后与三极管 Q16集电极连接，电阻 37串接在电源 Vcc与三极管 Q16集电极之间， Q16发射极串接二 极管 D7后接地， Q16基极与三极管 Q17集电极连接， Q17集电极与 电阻 R39串接后接地， Q17发射极串接电阻 R38后接电源 Vcc，Q17 基极与电阻 R40和电容 C13的接点连接，电阻 R40、电容 C13与电 阻 R41串接后，一端接电源 Vcc，另一端接点火大功率管的输出端 C，电阻 R42串接在 Q17基极与 Q3的集电极之间。 FIG. 2 is a circuit schematic diagram of an engine ignition device for continuous breakdown discharge of the present invention. It is composed of an energy storage device I and the high-frequency generating device Π of the present invention. The high-frequency generator is composed of integrated block UA2 (CA555), transistors Q17, Q16, diode D7, capacitor C13 and resistor R36, R37, R38, R39, R40, R41 and R42. The 3 pin of UA2 is connected to the output terminal Y of the energy storage ignition control circuit via a resistor R36. The 2 and 6 pins of the integrated block UA2 are connected to the triode Q16 collector, and the resistor 37 is connected in series to the power source Vcc and the triode Q16 collector. The Q16 emitter is connected in series with the diode D7 and grounded, the Q16 base is connected with the transistor Q17 collector, the Q17 collector is connected in series with the resistor R39 and grounded, the Q17 emitter is connected in series with the resistor R38 and connected to the power supply Vcc, and the Q17 base is connected to The connection point of resistor R40 and capacitor C13 is connected. After resistor R40 and capacitor C13 are connected in series with resistor R41, one end is connected to the power supply Vcc, and the other end is connected to the output terminal C of the ignition high-power tube. The resistor R42 is connected in series to the base of Q17 and Q3. Between the electrodes.
当储能控制线路在输出端 Y输出一个低电压信号时，点火大 功率管 CE截止，点火线圈 L1初鈒断路，点火线圈铁芯迅速退磁， 次线级圈产生电惑势，同时向分布电容充电到击穿电压条件时，火 花塞间隙产生击穿放电现彖，并同时产生一个负向升压现彖。 此时 C13两极间压差迅速升高，电流经 Q17的发射极和基极 EB向 C13 充电， Q17导通， Q16也导通， UA2的 2脚被触发， 3脚高电位输出， 大功率管导通，点火线圈初级通路，次级已储能量因大功率导通而 改变放电方向，在高于供电电压数十倍电压条件下经大功率管对地 放电，点火线圈铁芯被迅速磁化，此时 C13充电过程终了， Q17因无 电流通过而截止， Q16也截止， UA2的 6脚被触发，大功率管截止， 重复击穿放电过程。以此反复工作到点火线團已储能量不足以再产 生击穿所需的充磁能量时止。 此线路的放电频率在击穿电压 15KV 时工作在 5〜6KHz，放电时间 2MS。  When the energy storage control circuit outputs a low voltage signal at the output terminal Y, the ignition high-power tube CE is turned off, the ignition coil L1 is initially disconnected, the ignition coil iron core is rapidly demagnetized, and the secondary coil generates electrical confusion, and at the same time, it is distributed to the capacitor. When charged to the breakdown voltage condition, a spark discharge occurs at the spark plug gap, and at the same time a negative boost voltage occurs. At this time, the voltage difference between the two poles of C13 rises rapidly, the current charges Q13 through the emitter and base of EB Q17, Q17 is turned on, Q16 is also turned on, pin 2 of UA2 is triggered, pin 3 is high-potential output, and the high-power tube Continuity, the primary path of the ignition coil, the secondary stored energy changes the discharge direction due to high-power conduction, and is discharged to ground through the high-power tube under the condition that the voltage is tens of times higher than the supply voltage. The core of the ignition coil is rapidly magnetized. At this time, the charging process of C13 is ended, Q17 is turned off due to no current passing, Q16 is also turned off, pin 6 of UA2 is triggered, the high-power tube is turned off, and the breakdown discharge process is repeated. This operation is repeated until the stored energy of the ignition coil is not enough to generate the magnetizing energy required for breakdown. The discharge frequency of this line works at 5 ~ 6KHz when the breakdown voltage is 15KV, and the discharge time is 2MS.
集成块 UA2(CA555)为市场上可构得的时基集成电路。  Manifold UA2 (CA555) is a time-based integrated circuit available on the market.
点火大功率管为 MJ10012 ,是达林顿结枸的 NPN型大功率晶 体管，其功能是作为大功率开关。  The ignition high-power tube is MJ10012, which is an NPN high-power transistor of Darlington junction. Its function is to act as a high-power switch.
自动断电保护在高电位情况下是由 Q8、C8、Q9实现的。当高电 位信号大于 3 : 7信号时间时 Q8导通， C8反向充电到 Q9导通，此时 线路输出的是低电位，点火器大功率管截止。 工业应用性 从以上说明可以看出，本发明的连续击穿式发动机点火装置实 质上是从根本上改变了传统点火装置的点火原理，它产生高频连续 击穿放电现彖，大大地增加了击穿放电次数，提高了电能转换效率， 使储存能量得到充分利用，同时因高频击穿是在空气绝缘恢复后再 击穿的，电离数成倍增加，产生了更多的臭氣和单线态氡；高频击穿 放电使储能型点火的恒定磁场转变为交变磁场，产生了更强的磁场 效应，所以充磁速度快，能量大，每次击穿能量都不小于储能型的击 穿能量，真正起到了高頻点火的目的。 Automatic power-off protection is realized by Q8, C8, Q9 under high potential. When the high-potential signal is greater than 3: 7 signal time, Q8 is turned on, C8 is reversely charged until Q9 is turned on, at this time the line output is low potential, and the igniter high-power tube is turned off. Industrial applicability From the above description, it can be seen that the continuous breakdown engine ignition device of the present invention essentially fundamentally changes the ignition principle of the traditional ignition device. It generates a high-frequency continuous breakdown discharge, which greatly increases the breakdown discharge. The number of times has improved the efficiency of electric energy conversion and made full use of the stored energy. At the same time, because the high-frequency breakdown is broken down after the air insulation is restored, the number of ionizations has doubled, resulting in more odors and singlet plutonium; The high-frequency breakdown discharge converts the constant magnetic field of the energy storage ignition into an alternating magnetic field, which produces a stronger magnetic field effect. Therefore, the magnetization speed is fast and the energy is large. The energy of each breakdown is not less than the energy storage breakdown. Energy really plays the purpose of high-frequency ignition.
储能型点火装置在击穿放电后，因火源扩展使燃核温度下降及 燃烧过程中产生的散热量增加，火焰千涉等问题，使火焰面积缩小， 燃烧变慢，局部猝灭，造成燃烧不良。而本发明的连续击穿点火装置 利用已储能量在高頻发生电路的作用下，使击穿点火的击穿数增加 了数十倍，使燃核温度持续增加，因击穿放电较孤光放电的能量转 换率高，再加上连续击穿现彖发生时所产生的交变磁场作用，使氣 能转换率更高，在此作用下，使发动机燃烧速度快，反应更充分，提 高热效率和燃油经济性能，增加了发动机扭矩和输出劝率，减少有 害气体排放。  After the breakdown of the energy storage type ignition device, due to the expansion of the ignition source, the combustion core temperature decreases, the amount of heat generated during the combustion process increases, and the flame is involved. The flame area is reduced, the combustion is slowed down, and the local quenching is caused. Poor burning. The continuous breakdown ignition device of the present invention uses the stored energy under the action of a high-frequency generating circuit to increase the number of breakdowns of the breakdown ignition by tens of times, so that the combustion core temperature continues to increase, because the breakdown discharge is more isolated. The high energy conversion rate of the discharge, coupled with the alternating magnetic field generated when continuous breakdown occurs, makes the gas energy conversion rate higher. Under this effect, the engine burns faster, the reaction is more sufficient, and the thermal efficiency is improved. And fuel economy performance, increase engine torque and output persuasion rate, and reduce harmful gas emissions.
从动力学分析看，储能型点火器击穿放电后，只有一次点火脉 沖，参见图 3，该点火脉冲只能保存 1. 5ms的放电时间。  From the analysis of kinetics, after the energy storage igniter has a breakdown discharge, there is only one ignition pulse. See Figure 3. This ignition pulse can only save the discharge time of 1.5ms.
而本发明的连续击穿式点火器利用一个高频发生电路，在点火 装置不作任何改动的情况下可产生多次击穿点火，放电时间延长到 4ms以上  The continuous breakdown igniter of the present invention uses a high-frequency generating circuit, and can produce multiple breakdown ignitions without any modification of the ignition device, and the discharge time is extended to more than 4ms.
另外，本发明的连续击穿式点火器由于击穿点火频率增加，增 加了气缸内等离子量，从而促使空气中的氣迅速转化为单线态氣或 分裂为新生态氧原子而进一步^成为臭氡，由于单线态氣和臭氣的 键能均比基态氡的小，所以键易断裂，表现出强的活泼性而强烈地 参加燃烧反应，加快了反应速度，提高了燃烧效率，大大減少了汽车 尾气的排放量及积碳的生成，所以本装置能充分发挥减少排废，节 省燃油，增加发动机性能的作用。 综上所述.本发明的连续击穿式点火装置突破现有的储能式点 火方式，提高了能量转换效率。 熟悉本技术领域的技术人员将易于 理解，本发现还可以有多种改型。 本发明的保护范围由权利要求书 给出。 In addition, the continuous breakdown igniter of the present invention increases the breakdown ignition frequency and increases the amount of plasma in the cylinder, thereby prompting the gas in the air to be rapidly transformed into a singlet gas or split into new ecological oxygen atoms, thereby further becoming stinky Because the bond energy of singlet gas and odor is smaller than the ground state 氡, the bond is easy to break, showing strong activity and strongly participating in the combustion reaction, which accelerates the reaction speed, improves the combustion efficiency, and greatly reduces the automobile. Exhaust emissions and the formation of carbon deposits, so this device can fully play the role of reducing waste emissions, saving fuel and increasing engine performance. In summary, the continuous breakdown ignition device of the present invention breaks through the existing energy storage ignition method and improves the energy conversion efficiency. Those skilled in the art will readily understand that the present invention can be modified in various ways. The protection scope of the invention is given by the claims.
