Motorcycle electronic fuel saving circuit

The motorcycle energy-saving control circuit can automatically disconnect the magneto power supply circuit when the motorcycle battery is fully charged, so that the magneto is in a no-load operating
state, reducing the engine load and achieving the purpose of saving fuel. This device is suitable for motorcycles whose headlights are powered directly by the battery.
    Circuit working principle: The motorcycle energy-saving controller circuit consists of a voltage detection control circuit and a multivibrator, as shown in the figure.
    The voltage detection control circuit is composed of a resistor R], a three-terminal voltage stabilizing integrated circuit lcl; an operational amplifier integrated circuit 102, diodes VD1,
VD2, transistor VT1 and relay K. " The
    multivibrator circuit is composed of resistors Rfi-R., capacitors C,, C, light-emitting diodes LED and transistors VT2\VT3. The
    normally open contact Kl of the relay K is connected to both ends of the resistor R and is normally closed Contact K2 is connected in series in the output circuit of the magneto charging winding W. After
  turning on the lock switch S of the motorcycle
  +9V by lCl .As the working power supply of IC2.
