Ignition Coil – IC-13010

The ignition coil is the part that allows the spark plug to generate sparks and ignite the mixed gas in the cylinder. Normally, each cylinder is equipped with a set of ignition coils and spark plugs.
The ignition coil is mainly responsible for distributing the ignition sequence and conducting the high-voltage electricity pre-distributed by the distributor to the spark plug to ignite the inside of the cylinder. The number of ignition coils and ignition high-voltage wires is determined according to the number of cylinders of the engine.
The ignition coil converts low-voltage direct current into high-voltage electricity. The voltage can reach tens of thousands of volts. The spark plug in the cylinder breaks down the air and ionizes it to generate electric sparks. It repeatedly stores and discharges energy at different frequencies according to different engine speeds. When the primary coil is powered on, as the current increases, a strong magnetic field is generated around it, and the iron core stores magnetic field energy.
Under normal circumstances, the ignition coil is wrapped with two sets of coils, the primary coil and the secondary coil. The primary coil is made of thicker enameled wire, usually about 200-500 turns of about 0.5-1mm enameled wire; the secondary coil is made of thinner enameled wire, usually about 15000-25000 turns of about 0.1mm enameled wire. One end of the primary coil is connected to the positive pole of the low-voltage power supply (+) on the vehicle, and the other end is connected to the switch device (breaker). One end of the secondary coil is connected to the primary coil, and the other end is connected to the output end of the high-voltage line to output high-voltage power.
1. Open the engine compartment cover. If there is an engine cover, you need to remove it. At this time, you can see the exposed ignition coil of each cylinder of the engine.
2. Slowly lift the latch outward, being careful not to break the latch; then press the buckle handle downward while slowly pulling out the plug.
3. Use the corresponding socket tool to remove the fixing screws of each cylinder ignition coil, and pull out the ignition coil.
4. Install the core ignition coil back into the ignition coil hole. When installing it back, be sure to ensure that it is stably combined with the spark plug. Since each cylinder plug has its corresponding cylinder, do not mix them up.
5. Use fixing bolts to secure the ignition coil firmly, plug in the corresponding ignition coil plug of each cylinder, and push the socket pin inward to the locking position.
6. After the installation is completed, test whether the ignition coil is working normally. If everything is normal, put the engine cover back on the engine and you are done.
