Electronic Ignition does not use electro mechanical part as it was used in the ignition system of the older days. But it uses an electronic switching device which sends electrical impulses to the spark plugs and thereby ignites the fuel. These systems are more efficient as well as support higher engine horsepower levels than the primitive mechanically controlled systems. The major advantage of this system is that it is circuit based rather than mechanically controlled. It controls the electrical flow by using sensors, electrical switches and transistors in accurate and reliable manner. These are also durable. Thus, Electronic Ignition is better than the mechanically rotating distributor head in all respects. Due to its high level precision, it prevents incomplete combustion of fuel into the piston chamber of the engine which results in better fuel economy as well as reduces pollution. There are different types of electronic ignition available and it is also used for many systems that come with an electronic control. The first type comes with contact breakers that triggers and found on the earlier Premier Padmini. In the second type, it comes with breakerless or contactless ignition in which optical pickups or electronic transistors are used as the switching device. This is the most common type that is found on the modern cars. The third type is the capacitor discharge ignition and in this the energy stored in the capacitor is released through a coil all of a sudden. Electronic ignition also has the ability to maintain timing and at the same gives constant output over high mileage. It also has the ability to produce spark in marginal conditions where the conventional ignition would not work. It also helps the vehicle in achieving emission regulations. Due to the several benefits it offers, it has become a standard feature in the modern cars.
