- Ignition
- A process which initiates the combustion of the compressed air/fuel mixture in
the combustion chamber. In a spark-ignition engine, the mixture is ignited by an
electric spark; in a diesel engine, the self-igniting mixture must be preheated by
glow plugs when a cold start is performed.

- Ignition cable
- A general term to designate the high-voltage cables of the ignition system, from the ignition coil to the distributor and from the distributor to the spark plugs. Also called ignition leads
- Ignition capacitor
- The electrical part which interrupts the primary current with low loss and suppresses most of the arcing between the contact breaker points in conventional coil ignitions
- Ignition coil
-
A pulse Transformer which is a part of the Ignition system. It receives a small amount of electrical Voltage from the Battery and steps up the low primary voltage and amplifies it into a big jolt of voltage of about 20,000 volts, and sends it to the Spark plugs via the Distributor. It is made of two windings and a Core of iron. The primary coil has about 200 turns of relatively heavy wire. The secondary windings may have as much as 22,000 windings of fine wire. As electricity travels through the Primary winding, it produces a Magnetic field in the coil. When the points open, the magnetic field collapses and the movement of the magnetic field induces Current in the secondary windings of the coil. The voltage is stepped up in proportion to the ratio of secondary to primary turns and the Distributor directs this high voltage to the Spark plug. Also called just coil.

- A general control unit of electronic ignition systems, usually with current and dwell angle control, driver and output stage, in some cases with electronic spark timing functions. Compare Electronic control unit
- Ignition file
- A tool for filing ignition points and other small objects. Also called Contact file, Magneto file, Points file, or Point file
- Ignition gauge
- A blade or wire-type feeler gauge used to check gaps on ignition systems, such as air gaps between permanent magnet and trigger wheel on electric ignitions
- Ignition key
- A key which is inserted into an ignition lock located in the passenger compartment (usually on the steering column or on the dash) and is used to switch on the ignition
- Ignition-latched soft code
- A type of trouble code that causes the ECU to disengage the ABS until the ignition is shut off and turned back on; if the problem has gone away, the ABS will be reactivated and the warning lamp turned out when the key is turned back on
- Ignition lead
- A general term to designate the high-voltage cables of the ignition system, from the ignition coil to the distributor and from the distributor to the spark plugs. Also called ignition cable
- Ignition map
- An electronic map stored in the electronic control unit of ignitions with electronic spark timing and containing the most favorable ignition angle/ignition point for every operating point of the engine. Spark timing is optimized on the basis of fuel type and consumption, torque, exhaust gas, knock limit, engine temperature, etc.
- Ignition module
- A transistorized component in an electronic ignition that triggers the ignition coil to fire high voltage. It replaced the breaker points on older cars.
- Ignition oscilloscope
- An oscilloscope used especially for ignition tune-ups; usually integrated in an engine tester
- Ignition pattern
- A display of the waveforms in the primary or secondary circuit of an ignition
system in the firing order of the engine; optionally parade or display pattern and
stacked or raster pattern.

- The moment of spark firing.
- Breaker points.
- Ignition primary
- The low-voltage part of the ignition circuit, such as part of the ignition coil wiring, the pickup, electronic ignition module, and ECM. Compare Ignition secondary
- Ignition secondary
- The high-voltage part of the ignition circuit, such as part of the ignition coil wiring, spark plugs, spark plug wires, distributor cap, and rotor. Compare Ignition primary
- Ignition switch
- A control device that is generally operated with a key that closes and opens an electrical Current to connect and disconnects the Ignition system from the Battery so that the engine can be started and stopped as desired. The key should not be removable when the engine is running. It usually has various positions which, besides starting the engine, allow the user to operate the Accessories without engaging the engine or to check the Bulbs in the warning lights on the Dashboard.
- Ignition system
- The system that provides the electrical Current or
Spark to ignite the
Air-fuel mixture in the
Combustion chambers. It includes the
Battery or Magneto
which sends electricity to the Ignition coil if
the Ignition switch is on. The coil amplifies
the electrical charge and sends it to the
Distributor where it goes through the points and
is modified by the Condenser. The
Distributor sends it along the high tension lines
(Spark plug wires) to the
Spark plugs where it ignites the air-fuel mixture.

- Ignition timing
- It is important that the Spark coming from the Spark plugs ignites the Air-fuel mixture at the correct moment determined by the manufacturer of the engine. Often this is a few degrees Before top dead center (BTDC). Suppose the specs indicate that it should be set at 5 degrees BTDC, but in actuality it is set at 6 degrees. In that case, the Timing is advanced. If it were set at 4 degrees, the timing is Retarded. Incorrect ignition timing may result in poor performance and excessive fuel consumption.
