INDUCTIVE DISCHARGE IGNITION Meaning and
Definition
-
Inductive discharge ignition is a system used in internal combustion engines to ignite the fuel-air mixture inside the combustion chamber. It is a type of ignition system that uses electromagnetic induction to generate a high-voltage spark at the spark plugs.
In an inductive discharge ignition system, a low-voltage current is supplied by the battery through the ignition switch to the primary winding of an ignition coil. The primary winding is connected to a triggering device, such as an ignition module or points, which control the timing of the ignition spark. When the triggering device signals, it interrupts the current flow through the primary winding, causing the magnetic field in the coil to collapse. The collapsing magnetic field induces a high voltage in the secondary winding of the coil due to the principle of electromagnetic induction.
This high voltage is then transferred through the distributor to the spark plugs, where it creates a spark across the spark plug gap. The spark ignites the compressed fuel-air mixture in the combustion chamber, initiating the combustion process.
Inductive discharge ignition systems are widely used in gasoline engines, providing reliable ignition and efficient combustion. They offer precise control of ignition timing and can handle high voltage outputs, ensuring a strong and consistent spark. However, they require periodic maintenance, such as checking and replacing spark plugs, distributor cap, and rotor, to ensure optimal performance and prevent misfires.
