An ignition system generates a spark or heats an electrode to a high temperature to ignite a fuel-air mixture in spark ignition internal combustion engines, oil-fired and gas-fired boilers, rocket engines, etc. … They usually have glowplugs that preheat the combustion chamber to allow starting in cold weather.
There are three basic types of automotive ignition systems: distributor-based, distributor-less, and coil-on-plug (COP).
The ignition takes place inside the cylinder at the end of the compression stroke, the ignition system serves this purpose. It is a part of the electrical system which carries the electrical current to a current plug. It gives the spark to ignite the air-fuel mixture at the correct time. Read our full article on I.C.
Currently, we recognize four types of ignition systems used in most cars and trucks: conventional breaker-point ignitions, high energy (electronic) ignitions, distributor-less (waste spark) ignition and coil-on-plug ignitions.
Conventional Ignition System. … When the ignition key is turned on, a low voltage current from the battery flows through the primary windings of the ignition coil, through the breaker points and back to the battery. This current flow causes a magnetic field to form around the coil.
The primary function of an ignition system is to create an electric spark in the engine combustion chamber at the proper time so that the petrol and air mixture can ignite. It produces 30,000 volts across the spark plug. High spark voltage spark is supplied to each spark plug in the correct sequence.
Ignition systems can be divided into two classifications: magneto-ignition systems or electronic Full Authority Digital Engine Control (FADEC) systems for reciprocating engines. Ignition systems can also be subclassified as either single or dual magneto-ignition systems.
- Engine misfires.
- Rough idle.
- A decrease in car power, especially in acceleration.
- Poor fuel economy.
- Difficulty starting the engine.
- Check engine light is on.
- Exhaust backfiring.
- Increased hydrocarbon emissions.
You can easily tell which you have when you pop the hood by looking at the spark plugs. If there are thick wires all running to the same location, you’ve got an electronic ignition system.
- Conventional Ignition Coil.
- Electronic Ignition Coil.
- Distributor-less Ignition Coil (DIS)
- Coil-on-Plug Ignition Coil (COP)
Transistorized ignition systems make it possible to send heavier current through the coil without burning the points. … When the points open, the control circuit is broken, the power circuit is therefore turned off and the magnetic field inside the coil collapses.
1 : the act of causing something to start burning. 2 : the process or means (as an electric spark) of causing the fuel in an engine to burn so that the engine begins working. 3 : a device that is used to start a motor vehicle Put the key in the ignition.
- Breaker-Point Ignition System. …
- High Energy (Electronic) Ignition System. …
- Distributorless Ignition System. …
- Coil-on-Plug (Direct) Ignition. …
- Capacitor Discharge Ignition (CDI) System For Small Engines.
Most now use a magnetic device, called a reluctor, that is operated by the distributor shaft to produce timed electric signals, which are amplified and used to control the current to the induction coil.
- The first step is removing the spark plug you want to look at. …
- A normal spark plug will have brown or grayish-tan deposits on the side electrode. …
- Black, dry soot on the electrodes and insulator tip indicates a carbon-fouled plug. …
- Black, oily deposits on the electrodes and insulator tip points to an oil-fouled plug.
