  Furthermore, in order to improve the combustion efficiency of the engine, lower fuel consumption, and lower exhaust gas, there have been cases in which high-density negative ions are released into the air-fuel mixture and combustion exhaust gas of the engine.

  As these conventional techniques, Patent Documents 1 to 3 shown below are known. For example, a general vehicle engine ignition device disclosed in Japanese Patent Laid-Open No. 5-106544 of Patent Document 1 is a microcomputer. It is shown that the input signal from is switched and amplified by an igniter having a switching circuit for one circuit, and the switched and amplified signal is increased in voltage by an ignition coil to ignite a spark plug.

  However, in the method for generating negative ions for automobiles in Patent Document 2, it is necessary to replace an engine crankshaft, a piezoelectric ceramic module, and the like in order to attach to an existing vehicle. There were problems such as. Further, in the battery voltage stabilization device disclosed in Patent Document 3, a voltage corresponding to a voltage drop generated only when a sudden load change of the engine is performed is discharged from the electrolytic capacitor element of the voltage stabilization circuit. Therefore, the distance between the ignition coil power supply and the battery is inevitably increased, which is generated by the ignition coil primary current cutoff or the spark plug spark current. There is a problem that the pulse voltage to be removed cannot be removed. In addition, when such a device is connected between the (+) power source of the ignition coil and the vehicle body ground (-), the ignition key is charged by the inrush current charged to the electrolytic capacitor element each time the vehicle ignition key switch is turned on. There is a problem in that the relay contact for power supply to the ignition coil that moves in conjunction with the switch or the ignition key switch is damaged.

  According to a first aspect of the present invention, there is provided a voltage stabilizer having a high capacity capacitive load and a capacitive load having a good frequency response between an ignition coil power supply (+) and a body ground (-) of the vehicle. By connecting the, the pulse voltage generated when the primary current of the ignition coil is interrupted or by the spark current of the spark plug can be removed, and by removing the pulse voltage, the rise of the voltage at the initial stage of ignition becomes steep. The problem is solved by ionizing the air-fuel mixture in the engine cylinder.

  According to claim 2, the problem is solved by adding a circuit for regulating the current for a certain period during energization to prevent damage to the key switch and relay contact of the vehicle due to the inrush current generated when energizing the capacitive load. Is done.

  According to the third aspect, at the time of attachment to the vehicle, the problem is solved by connecting to the ignition coil or key cylinder of the vehicle using a dedicated harness or connecting to a cord drawn out from the terminal of the fuse.

According to the present invention, by connecting a voltage stabilizer having a high capacity capacitive load and a capacitive load with good frequency response between the ignition coil power supply (+) and the body ground (−) of the vehicle, the ignition coil In addition to removing the pulse voltage generated when the primary current is shut off and the spark current of the spark plug, a sharp rise in the voltage at the initial stage of ignition generates a high frequency and ionizes the air-fuel mixture in the engine cylinder. As a result, the primary coil current decreases due to a momentary voltage drop due to the current flowing through the primary coil of the ignition coil and the wiring resistance, and the magnetic field energy accumulated in the ignition coil decreases, reducing the ignition plug It became possible to prevent the spark from weakening. In addition, by using a capacitive load with good frequency response, etc., a voltage pulse generated when the primary current is cut off, or a voltage pulse generated by the inductance component of the wiring between the battery and the ignition coil when the spark plug is sparked. As a result, the response to the ignition signal is improved, and the rising of the voltage at the initial stage of ignition of the spark plug becomes steep, so that a higher voltage can be generated. As a result, high-frequency radio waves are emitted from the spark plug, thereby exciting the air-fuel mixture in the engine cylinder and causing ionization. When the air-fuel mixture is ionized, electric repulsion and suction occur, and the mixed state of gasoline molecules and oxygen molecules becomes uniform. When sparks are ignited with spark plugs in this uniform air-fuel mixture, ideal engine combustion can be obtained, and it has become possible to provide a voltage stabilizer specialized for improving engine performance It is.
Furthermore, since it is only necessary to make an electrical connection between the ignition coil power supply (+) and the body ground (-) of an existing vehicle, it can be installed very easily, and the installation cost can be reduced. It was.

BEST MODE FOR CARRYING OUT THE INVENTION

Next, the present invention will be described in detail with reference to FIGS. FIG. 1 is a circuit diagram of an embodiment of the present invention, FIG. 2 is a block diagram of a conventional independent ignition device for a general four-cylinder vehicle, and FIG. 3 is a detailed diagram of the ignition device of FIG.
As shown in FIGS. 2 and 3, in the conventional independent ignition device for a vehicle, an ignition signal is sent from the engine computer (10) to the ignition device (8). The sent ignition signal is amplified by a transistor in the ignition device (8) and is increased in voltage by an ignition coil. The high voltage energy is sent to the spark plug (9) and sparked, causing an explosion in the engine cylinder. FIG. 4 shows a waveform diagram of the ignition coil power supply at this time. (Point 3A)
In FIG. 4, (4-1) is a current drop (I1) flowing through the primary coil of the ignition coil and a voltage drop caused by wiring resistance, etc. (4-2) is when the primary current (I1) is cut off (transistor (4-3) is a voltage pulse generated by the inductance component of the wiring between the battery (3) and the ignition coil when the spark plug (9) is sparked.
As described above, in the conventional independent ignition device for a vehicle, it is difficult to say that a voltage drop or a voltage pulse is generated and the performance of the engine is efficiently exhibited.

  The voltage stabilizer of the present invention shown in FIG. 1 includes a charge amount regulating circuit 1 and a capacitive load group 2, and this device is connected to a power source (+) line of an ignition coil, and a key switch (7) is turned on. Then, the charge amount regulation circuit 1 is charged to the film capacitor element (C1) and the electrolytic capacitor element (C2) from (P1) through (D2) and (R2). At this time, the current flowing to (C1) and (C2) is limited by (R2). Until (C1) and (C2) are charged to some extent, (Q1) and (Q3) are on, and (Q2) is off at this time, so (L1) is off. When (C1) and (C2) are charged to some extent, (Q1) is turned off. When (Q1) is turned off, (Q3) is also turned off and (Q2) is turned on. When (Q2) is turned on, (L1) is turned on and the remaining charge is charged. As a result, it is possible to prevent damage to the key switch and the relay contact, and it is possible to remove the pulse voltage generated when the primary current of the ignition coil is interrupted or due to the spark current of the spark plug.

Next, when the key switch (7) is turned off, when the voltage of (P1) becomes equal to or less than "ZD1 voltage + ZD2 voltage + Q2 base-emitter voltage", (Q2) is turned off and (L1) is turned off. The
With this configuration, it is possible to prevent the occurrence of an inrush current even when the key switch (7) is turned on again. In addition, the falling speed of the voltage of (P1) is increased, and adverse effects on the after-idling device (see JP-A-11-78685) and the like can be eliminated.

FIG. 5 shows a waveform diagram of the ignition coil power supply after the installation of this device (waveform diagram at point A in FIG. 3). Current flowing to the primary side by the electrolytic capacitor element (C2) and voltage due to wiring resistance, etc. The depression is relaxed as in (5-1). Further, the voltage pulse generated when the primary current is cut off by the film capacitor element (C1) and the voltage pulse generated when the spark plug (9) is sparked are relaxed as shown in (5-2), and the waveform diagram of FIG. It can be seen that the voltage drop and the voltage pulse are alleviated as compared with FIG.
Further, in order to improve the frequency response and ensure more capacitive loads, a plurality of electrolytic capacitor elements (C2) of the capacitive load group 2 may be used as shown in FIG.

By attaching this device configured in this way, the voltage rise of the spark plug at the initial stage of ignition is steep and high frequency is generated, ionizing the mixture in the engine cylinder, causing electric repulsion and suction, and gasoline molecules And oxygen molecules are mixed. When sparks are ignited with spark plugs in this uniform air-fuel mixture, ideal engine combustion can be obtained, and it has become possible to provide a voltage stabilizer specialized for improving engine performance It is.
Furthermore, since it is only necessary to make an electrical connection between the ignition coil power supply (+) and the body ground (-) of an existing vehicle, it can be installed very easily, and the labor and cost for installation can be reduced. It became.
In the above-described embodiments, the electrolytic capacitor element and the film capacitor element are used as the capacitive load. However, it is needless to say that the capacitive load has the same characteristics as the electrolytic capacitor element and the film capacitor element.
