Usefulness Of Electronic Ignition System Over Other Ignition Systems
Usefulness Of Electronic Ignition System Over Other Ignition Systems:
Most of the automobile owners are familiar with the term ‘ignition system’. However, very few of them are aware of the type of ignition system their vehicles are running on. Since the origin of vehicles, the ignition system gone through various advancing levels. From the points and distributors to the distributor less ignition systems, automobile industry witnessed huge changes in productivity and reliability of vehicles. Among all the valuable ignition systems, the most reliable and longest running one is the ‘Electronic Ignition System (EIS)’.
Electronic Ignition System or EIS is said to be the modified form of Conventional Ignition System. It is slightly different than the mechanical ignition system and is still operative in several kind of engines. Ignition system is an essential part of each vehicle as without it a vehicle will not start. Basically, all vehicles and generators require an electric spark in order to power their engine. The type of ignition system and ignition timing defines its efficiency.
How EIS or Electronic Ignition System Is Better Than Its Counterparts:
Many types of ignition systems have been produced till today but not all of them are still in use. If we go back in history of engines, we found that the Magneto systems are the oldest ignition systems. They were the simplest kind of ignition systems that used a magnet inside the coil and circuit breaker. The magneto system is not used in modern cars but in some small engines. The magneto system was not a very reliable system as it was difficult to start and was totally dependent on engine’s speed.
Another popular ignition system of the past was Conventional Ignition System. It is also not used in modern cars. This system comprises points, distributor and an external coil. The disadvantage of conventional ignition system is that it uses point breakers for disrupting the low voltage high current. These points are often get impaired during the activity. Regular adjustments and maintenance is required to keep running these points which makes them a bit expensive too.
The Electronic Ignition System or EIS is definitely not the latest ignition system but it is still used widely in many engines. In EIS, the points are substituted by a pickup coil. In addition, it also possesses an armature and electronic control module which lacks in former kind of ignition systems. These additional electronic parts make it more effective and significant than its counterparts. Because of the lack of point breakers, it is not subjected to mechanical wears and instability. It works more smoothly and speedily than the mechanical ignition system.
How Electronic Ignition System (EIS) Works?
Electronic Ignition System (EIS) start functioning as soon as the ignition switch is turned on. First of all, the battery starts producing current which passes the ignition switch and enters the coil’s primary windings. Then the pickup coil sends signal to the electronic control module, after receiving these signals, electronic control module stops flow of current from primary circuit. But when reluctor tooth of the module rotates away from the pickup coil the current will again start flowing from the primary circuit. This making and breaking of circuit generates a magnetic field in ignition coil. Then the magnetic field collapses which in turn produces the high voltage in coil’s secondary windings. The high voltage of about 50,000 volts is then transferred to the distributor. Inside the distributor, a rotor revolves according to ignition timing. When it comes near the distributor point, the voltage is transferred to distributor. From distributor the voltage is transferred to the spark plugs where eventually the spark is produced.
