This ignition device consists of an igniter and an ignition coil that is integrated into a single unit. In the past, high-voltage current was sent to the cylinders via high-tension cords. Now, an ignition Read more Ignition coil united with igniter
Ignition
ESA (Electronic Spark Advance)
The engine ECU, which receives signals from various sensors, calculates the ignition timing and transmits ignition signals to the igniter. The ignition timing is calculated continuously in accordance with Read more ESA (Electronic Spark Advance)
Spark Plug
The high voltage generated in the secondary winding of the ignition coil produces a spark between the center and ground electrodes of the spark plug in order to ignite the air-fuel mixture that is compressed Read more Spark Plug
Platinum/Iridium-tipped Plug
On the platinum-tipped and iridiumtipped spark plugs, the center electrode and the opposing ground electrode are covered with a thin platinum or iridium tip. Therefore, these spark plugs provide a longer Read more Platinum/Iridium-tipped Plug
Automotive Igniter
Outline
The igniter carries out the precise interruption of the primary current that flows to the ignition coil in accordance with the ignition signal (IGT) that is output by the engine ECU.
Necessity of Ignition Timing Control
In a gasoline engine, the air-fuel mixture is ignited to cause combustion, and the force that is generated by the explosion causes the piston to push downward. The thermal energy can be most efficiently Read more Necessity of Ignition Timing Control
Automotive Ignition System
The three essential elements of a gasoline engine aregood air-fuel mixture, good compression, and good spark. The ignition system generates a powerful spark through proper ignition timing in order to ignite Read more Automotive Ignition System
TDI (TOYOTA Direct Ignition System)
In the TDI system, the conventional distributor is no longer used as in the ignition system. Instead, it provides an ignition coil with an independent integrated igniter for each of the cylinders. Because Read more TDI (TOYOTA Direct Ignition System)
Automotive Ignition Coil
The ignition coil generates a high voltage that is sufficient for arcing sparks between the electrodes of a spark plug. The primary and secondary coils are wound around the core. The secondary coil is Read more Automotive Ignition Coil
