FIG. 1 is a schematic structural diagram of a high-efficiency energy-saving device for a zero-emission motor vehicle according to an embodiment of the present invention.

Detailed ways

The technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

The high-efficiency energy-saving device for zero-emission motor vehicles in the embodiment of the present invention includes: an induction system, an ignition system, and a fuel fine control system; wherein the induction system senses the working state of the engine flywheel rotation to obtain an energy operation command; The induction system performs ignition according to the operation instruction of the induction system; the fuel fine control system is connected to the induction system to supply fuel according to the operation instruction of the induction system.

As shown in FIG. 1 , the induction system includes an engine induction coil L, a magnet is arranged on the engine flywheel, and the engine induction coil L is arranged on the side of the engine flywheel to sense the energy working state of the engine flywheel rotation.

As shown in Figure 1, the ignition system includes: ignition coil L3, secondary ignition coil L4, ignition switch K1, variable frequency igniter C1, an amplifier composed of C1, C2, D1, D2, C3, C4, D3, and D4 Circuit, rectifier diode D6, thyristor SCR, discharge capacitor C5; wherein the positive pole of the ignition switch K1 and the variable frequency igniter C1 are connected to the positive pole of the engine induction coil L; the negative pole of the discharge capacitor C5 is connected to the ignition coil L3, and the second The first-stage ignition coil L4 is connected with the spark plug W; the engine induction coil L generates an induced voltage when the engine flywheel rotates, and after being amplified by the frequency conversion igniter C1 and the amplifying circuit, the discharge capacitor C5 is charged by the rectifier diode D6; and the engine induction The induced voltage of the coil L passes through the rectifier diode D7 and then is sent to the control pole of the thyristor SCR to turn on the thyristor SCR; the discharge capacitor C5 discharges through the thyristor SCR and the ignition coil L3 to make the secondary ignition coil L4 produce After the high voltage, the spark jumps through the spark plug W discharge.

Among them, the positive terminal of the engine induction coil L is connected to the positive terminal of the ignition switch K1 and the negative terminal of the variable frequency igniter C1, the negative terminal of K1 is connected to the negative terminal of D1, the negative terminal of the discharge capacitor C5 is connected to the ignition coil L3, and the ignition coil L4 is connected to the positive terminal of the spark plug. The negative terminal is grounded.

When the flywheel of the engine rotates, the electromotive force is induced by the induction coil. After passing through C1, C2, D1, D2, C3, C4, D3, and D4, the circuit voltage is amplified and rectified by D6 to charge the capacitor C5 to about kilovolts. As the flywheel rotates continuously, the induced potential in the coil is caused by triggering the induction coil, which is added to the control pole of the thyristor SCR through D7, and the thyristor is turned on at this time. At this time, the capacitor C5 discharges through the thyristor SCR and the ignition coil, so that the secondary L4 of the ignition coil generates a high voltage of more than 10,000 volts, and discharges and flashes through the gap of the spark plug. When the flywheel magneto of the engine rotates continuously, when the negative half cycle of the alternating current of the charging coil is reached, when the cathode voltage of the thyristor is higher than the anode voltage, the thyristor is cut off, and the generator coil charges the capacitor C5 through D6.

In this new type of ignition system, every time the crankshaft of the engine rotates once, the alternating current generated by the generator coil changes for two weeks, charging the capacitor C5 twice, so that the energy released by the capacitor C5 makes the induction voltage of the ignition coil higher, and the spark plug It is easy for high-voltage discharge to flash over, which is beneficial to speed up the process of starting and completely fueling the combustible mixture in the cylinder. In this way, the purpose of energy saving, emission reduction and environmental protection is realized.

As shown in Figure 1, the fuel fine control system includes: an encoding integrated circuit NE555 and a decoding integrated circuit M567; the trigger end of the encoding integrated circuit NE555 is connected to a frequency modulation circuit composed of a resistor R11 and a capacitor C11, and the output end is connected to a resistor R12, A power amplifier circuit composed of capacitor C12, transistor TV1 and transistor TV2. The input end of the decoding integrated circuit M567 is connected through a frequency conversion circuit composed of an inductance coil L2, a rectifier diode, resistors R13, C13, and C14; The circuit consists of resistors R14, TV3 and diode D11. The resistor R11 is installed on the gas pedal of the motor vehicle, and the switch K2 is installed on the engine mixture air inlet. The coupler is composed of the primary inductance coil L1 of the inductor and the secondary inductance coil L2 of the frequency conversion circuit. When the motor vehicle is started and used, the resistance value of the R11 potentiometer changes accordingly, and at the same time the potential of L1 changes, the potential of the coupler L2 also changes at the same time, the induced potential generated by M567 also changes synchronously, and the potential frequency of the solenoid valve switch K2 It is also changing, so as to achieve frequency conversion and precise engine fuel supply demand, so that fuel can be distributed according to demand. Through such precise distribution, the fuel can be used to the best of its ability, thus achieving the first step of energy saving and emission reduction. The second step of energy saving and emission reduction is that the firepower distribution of our ignition circuit is very uniform and strong, so that the fuel mixture can be fully, completely and efficiently burned in the cylinder, and the engine can output the strong power it deserves. The third step for energy saving and emission reduction is that when the motor vehicle turns off the power supply of K1, the solenoid valve switch K2 is immediately turned off, so that the piston of the flywheel cylinder of the engine will not inhale the fuel mixture during inertia, so that it will not discharge unused gas. The fuel mixture gas burned by the engine will not waste fuel and will not pollute the environment, making motor vehicles more energy-saving and environmentally friendly.

Anyone skilled in the art can easily think of changes or substitutions within the technical scope disclosed in the present invention.
