3 Ignition System in Cars and Their Functions
Many do not know or understand the ignition system in a car, even though the ignition system in this car is very important so that the car can ignite.
ads In order for the car to ignite, combustion from the combustion chamber is done by mixing gasoline and air so that the car has power and can move other than that it is supported by several other ignition system components, therefore the ignition system has an important role.
So the ignition system is to generate sparks on the spark plug when the piston reaches the dead point above which finally there is a combustion that produces motion and power, the ignition system used is an electric ignition system, where electricity is used as a spark, the electricity is taken from battery (See also: Complete Car Engine Components)
In the ignition system there are several important components . . . The components in the ignition system include: Battery / Accu Used as a provider of low voltage electricity (12 Volt)for coil Ignition Key The ignition key functions to disconnect the electricity from the battery to the ignition coil Coil Functioning to increase the electric tension received from the battery to a high pressure of around 10,000 20,000 Volts needed for ignition, To raise the electric voltage in the coil there are 2 coils and to the two coils wrapped around an iron core made of thin silicon steel rolled strictly, namely: Primary Coil.
(Primary Coil) Generates a magnetic field in the coil, resulting in induction on the coil of the coil . . . The characteristics of the primary coil are the large cross section but the windings are small
(150 300 turns) and are outside the secondary coil. Secondary Coil Functions to induce a higher voltage, which is then flowed to the spark plug to cause sparks, the characteristic of the secondary coil is to have a small cross section with very large windings.
(15,000 30,000) windings and are located inside the coil primary.
Distributor It functions to distribute high voltage current from the ignition coil to the spark plug spark plug contained in each cylinder.
High voltage cable / spark plug cable The function of spark plug cable is to deliver electricity from the car coil to the spark plug so that the electricity can be generated by sparks spark plugs to help the vehicle engine can run smoothly and optimally.
Spark plug The spark plug serves to generate electric sparks between the two electrodes to burn the gas mixture in the combustion chamber, the spark is obtained from the high voltage generated by the igntion coil.
There are several methods needed to produce the high voltage current needed during the combustion process. The ignition system in the car serves to increase the battery voltage to 10KV or more by using the ignition coil and then by the distributor on the spark plug so that the spark is distributed through a high voltage cable, ignition coil or commonly called a coil is a core component of an ignition system that serves to produce high voltage electricity so that the process occurs.
Observed from the type of ignition, the ignition system has four types with differences in the way it works, but in its principle both use electromagnetic induction. Ignition system in cars Link Sponsors,1,conventional ignition system This model is the ignition system in the car that was first designed, this system relies on distribution engineering and platinum as the core of the distribution of sparks so that combustion occurs in the combustion chamber, this model is the basis of ignition systems such as CDI and DLI, the basic principle is a mechatronic circuit which aims to generate sparks on spark plugs, by utilizing high-voltage electrical energy obtained from the induction process on the coil.
In the coil there are two coils, namely primary and secondary coils, both of which have the same electric current input, but for different outputs, so the primary coil has an output that leads to the circuit breaker while the screw has an output leading to the spark
plug.In this system, it is widely used in older cars such as early generation kijang and colt. The workings of a conventional ignition system are quite simple.
When the contact is in the ON position, the electric current from the battery or battery flows to the coil and goes to platinum.
this position of the machine has not been spinning or has not started then the platinum will connect the current to the mass, giving rise to magnetism in the primary coil.
When the engine starts or you hear the sound of the engine, platinum will break when the cam touches the platinum foot, so that the magnetism of the primary coil moves to the secondary coil to produce high voltage which is channeled directly to the spark plug for the sprinkling process of fire, but sparks it is only needed during the business steps.

Constraints on conventional ignition systems on gasoline-fueled cars are the most common compared to other systems . . . Usually the obstacles that occur include the engine does not want to live, the engine is difficult to live because of sparks in small spark plugs until the most frequent thing is the explosion.
Usually this is caused by ignition components that are quickly dirty are spark plugs, platinum, rotor ends and terminals on the distributor cap, so it needs to be done periodically maintenance, these parts need to be examined and cleaned using sandpaper, ignition system components lubricants need to be given are Nok and Rubbing block, Nok Shaft and Centrifugal Advancer, as well as setting the ignition system includes setting spark plug slits, platinum slits or large dwell angles, and setting the ignition.

2 ,, transistor ignition system In principle, this system is the same as conventional ignition systems, which distinguishes platinum is not used but a transistor . . . Its function is to replace the role of platinum, usually known as an electronic ignition system.
The ignition transistor system utilizes transistor components as electronic switches for premier circuit breakers and produces electromagnetic induction.
The pengaian system in this car was introduced in 1955 by Lucas, at that time the ignition device was used in the BRM and Climax F1 Conventry cars, many still using mechanical components in conventional ignition systems.
Ignition of a transistor system (electronic) is divided into two types: Semi transistor ignition system This system still uses platinum contact, but it does not function to break the coil's primary current, but rather to disconnect the current towards the base foot of the transistor.
Fully transistor ignition system The second system does not use platinum or pure electric ignition. To disconnect the current at the base of the base, a device is used as an igniter that will send the signal according to the ignition timing to disconnect the current at the base of the transistor The working principle of ignition transistor (electronics) in the car is almost the same as conventional ignition and the difference lies in the way of primary current disconnection, but good ignition semi transistor and ignition fully transistor has different ways of working, on ignition semi transistor When the engine rotates, cam inside the distributor too spinning . . . That causes platinum to be open and closed . . .
When platinum is open or disconnected, the electrical current to the base of the base is also cut off, so the collector's and emitter's legs are cut off, while in fully transistor pulse igniter as a substitute for the role of platinum as a breaker and opening the flow of electric current.

ads 3,,DLI ignition system (Distributor Less Ignition) This means that the ignition system without involving a distributor, is an ignition system that has been controlled by a computer, on this system has been using EFI, ignition control is done by electronic control unit (ECU), by removing the distributor it will increase the reliability of the ignition system by reducing a number of mechanical components, the working principle of DLI is the same as conventional ignition.
the main differences in conventional ignition systems and DLI are current termination media, in conventional ignition systems, current disconnections are carried out by platinum at certain angles, while DLI ignition systems are terminated by igniter on coil pack on ECM orders with the help of several sensors (Also read: Car Wheel Components) Benefits;Because it doesn't use platinum, DLI does not require adjustment.
Efficiency is also good Combustion is more accurate Rarely causes problems Deficiency ; Involves complicated electronic circuits Although it is rarely a problem, once a problem requires a scanner to detect it Price of components is relatively expensive In general, DLI works by changing the function of distributors and platinum on conventional machines using electronic components, so that both have the same principle, however, in DLI the distribution of sparks takes place electrically.
When the contact in the ON battery position supplies current to the ECM and Coil pack, so that there is a current stand by on the secondary coil, Ckp will send engine RPM data, while the CMP sends the data cylinder top position one.
The signal is then sent to the ECM to be managed together with data from other sensors to determine ignition timing according to engine conditions. The output of the ECM is a voltage signal sent to the ICM, while in conventional ignition the platinum will decide the primary current when the top position . . . But on DLI, ECM will disconnect the primary current when the top position, Secondary coil voltage is channeled to the spark plug for sprinkling
fire in each cylinder, there are two types of circuits
commonly used in cars, namely dual coil pack and single coil pack.
