Power Transistor: Description and Operation
The igniter has the section to judge the severity of detonation and a section to control the ignition timing. Based on the signal from the detonation
sensor, the igniter judges detonation and controls ignition timing. The igniter incorporates a fail-safe feature which retards the ignition timing by a fixed
angle, except at idle, to protect the engine in the event of detonation sensor failure.
