Pontiac Firebird Ignition System
About Ignition System
The ignition system is used to firing the ignition plugs. The ignition switch is linked to the battery of the vehicle. When the key is switched on or the start button is activated, the power is redirected to the ignition relay. The relay enables low current and lighter gauge wire to control the high current required to supply the ignition coil, eliminating the danger and difficulty of high current routing to the ignition switch. The control circuit and the power circuit are within the relay. When the power is transmitted to the relay, the current is applied to the relay coil, producing a magnetic field that closes the control circuit contacts and transmits the voltage to the ignition coil. If the ignition relay is defective, the ignition will not be powered and the engine will not operate. The ignition system contains an engine crankshaft speed sensor, a knock sensor, a camshaft position sensor, an ignition coil, a distributor, a high voltage cable, and a spark plug. Electronic Control Module (ECM)-ECM is the core of the ignition system. The ECM regulates when a spark happens, based on the feedback of the various sensors on the engine. Distributor-The distributor enables the high voltage of the ignition coil to be transmitted to the spark plug in the correct order. The distributor also includes a sensor, often alluded to as a camshaft position sensor. The input from this sensor, working along with the ignition control unit, enables the ECM to determine precisely when to open the ground circuit of the primary ignition coil winding, which produces the high voltage needed to produce an electrical spark at the spark plugs. Ignition Coil-The ignition coil requires 12 volts from the vehicle battery to produce high voltage and create a spark in the spark plugs. In fact, the ignition coil consists of two different wire coils, the primary and the secondary. The primary coil is supplied with 12 volts from the ignition switch. The flow of current through the primary coil wiring generates a magnetic field, and if the negative side of the primary coil wiring gets exposed or ungrounded, the magnetic field collapses, creating a high voltage in the secondary coil winding. This high voltage flows through the coil wire to the distributor, then through the spark plug wire, and finally to the spark plug. Knock Sensor-The Knock Sensor detects detonation or pre-ignition from the engine block. The sensor makes a small amount of voltage when the engine starts knocking. The ECM reads the signal and the timing of the ignition is slightly delayed to avoid detonation. Crankshaft/Camshaft Position Sensor-This sensor records the exact position of each piston and the orientation of the valve in the engine. The feedback from the position sensor of the crankshaft and camshaft enables the ECM to monitor exactly when the ignition takes place.
Spark plugs, ignition coils, and distributors are major elements of the ignition system. Apart from these systems, the engine cannot run without other systems like relays, sensors, switches, and control units. These minor components perform crucial functions, such as the safe operation of high current levels, the supervision of critical information to ignition modules and engine control computers, and the execution of instructions based on those inputs for effective spark delivery. Electronic components in modern ignition systems generate higher voltage and more accurate ignition timing as compared to mechanical components. These systems provide a more powerful spark for complete combustion and improved performance, higher fuel efficiency, and reduced emissions.
