Getting rid of the plug wires not only saves money it also improves the durability of the ignition system. This video explains how the direct ignition system works dis.
Honda Nt650 Service Manual Section 16 Ignition System
Coil on plug ignition system diagram. A high tension magneto generates a very high voltage needed for spark plug. Older systems used a points and condenser system in the distributor newer as in most well ever see anymore use an ecu a little brain in a box to control the spark and make slight changes in ignition timing. This will cause the transistor base to be active so that the collector is connected to the emitter. Use a 5 volt. No high voltage wires means no voltage leaks and no misfires due to bad plug wires. Wrapped around it is the secondary coil.
Coil coils ignition plug created date. The distributorless ignition system may have one coil per cylinder or one coil for each pair of cylinders. Also known as coil on plug ignition system check out my other channel. System voltage for the command pulse. The secondary coil normally has hundreds of times more turns of wire than the primary coil. Spark plug timing is controlled by an ignition module and the engine computer.
The figure given on the next page shows the line diagram of the magneto ignition system. No dtcs for coil unplugged. Some coils have an internal resistor while others rely on a resistor wire or an external resistor to limit the current flowing into the coil from the cars 12. Coil on plug ignition system on a general motors vortec 3500 engine. Transisorized ignition system working procedure when the engine is started the crankshaft will rotate the pick up coil so that the pick up coil generates a low voltage current. In the magneto ignition system a magneto is used to generate electric current for producing the spark.
The spark plugs are fired directly from the coils. The spark plug is a familiar part of a cars ignition system and one that is routinely replaced typically as part of a cars major service. Using individual coils for each spark plug also means the coils have more time. The coil is a simple device essentially a high voltage transformer made up of two coils of wire. The same goes for the spark plug wires on cars that still use them. The trouble is the coil is an unknown quantity to many people.
The third type of ignition system is the distributorless ignition. Pulse amplitude does not change coil connected or not. One coil of wire is called the primary coil. The ignition system consists of an ignition coil distributor distributor cap rotor plug wires and spark plugs. An ignition coil also called a spark coil is an induction coil in an automobiles ignition system that transforms the dynamos voltage to the thousands of volts needed to create an electric spark in the spark plugs to ignite the fuel.
