Motorcycle Ignition System.

Is the working principle of motorcycle igniter igniter with sensors work to determine the spark plugs of fire point, also known as the ignition point, when the ignition coil amplifier voltage supply spark plug, spark to ignite the fuel and air mixture will explode, forces the pistons to move up and down inside the cylinder, so as to start the motorcycle engine.
Ignition magneto ignition coil and output of the ac voltage is divided into two way: by line 1 input, all the way to low voltage side of transformer, a path VDl after rectification, Cl filter for the trigger circuit composed of Vl, V2. When the engine starts up, the magneto output 4V a 5V ac voltage, and after the rectifying filter, the dc voltage of 5V ~ 6V is obtained. In the trigger circuit of Vl and V2, when the platinum contact is combined, Vl saturates the channel and the V2 ends. The collector of V2 is high potential, which is used to trigger the bidirectional controllable silicon VD3 and VD3 guide.
In addition, the low voltage ac voltage is increased by the transformer, and VD2 is charged to C2 after rectification. When the CAM of the engine disconnects, Vl intercepts E, and the collector of Vl is high potential, which can be controlled by R4, VD5, VD5 guide, C2 discharge, ignition coil ignition. On the other hand, due to the different design of the engine CAM, some of the protrusions of some cams reach more than 100 degrees, which means that the contact is disconnected to more than 100 degrees. Since the magneto is a quadrupole, the alternating voltage of each coil is changed for two weeks.
To prevent during off contact, also called VD5 conduction period, with a positive potential transformer high voltage side end, make the positive half cycle of high pressure after VD2, VD4 form a short circuit, therefore equipped with two-way thyristor switch circuit composed of VD3. As mentioned above, the contact is disconnected from V1, SCR leads, and V1 collector is high potential, which makes V2 saturation. The collector of V2 is low potential, and VD3 is shut off, thus avoiding the occurrence of the short circuit during the high pressure during the contact disconnection.
