Inductive energy storage electronically controlled ignition system

How is energy stored in an inductive ignition?

In an inductive ignition, the energy is stored directly within the ignition coil in the form of a magnetic field. When current is passed through the primary winding of the coil, energy is stored in the magnetic field.

What is the difference between a capacitive and inductive ignition system?

With inductive ignition systems more energy can be delivered to the secondary winding of the coil than in a capacitive ignition system. With the same power supply current draw, up to five times more energy can be delivered to the secondary winding of an inductive coil than to a capacitive coil.

Which engine developments require high energy ignition systems?

Other engine developments requiring high energy ignition systems include natural gas engines and cold-starting applications of diesel and methanol fuelled engines. This paper reviews progress on alternative ignition systems that supply higher energy sparks and sparks where the energy is more efficiently transferred to the gas mixture.

How does a computer controlled ignition system work?

Commonly, this included a vacuum advance mechanism to adjust the curve for engine load. With today's computer controlled ignition systems, a complex spark timing curve can be generated by the engine computer to optimize horsepower and efficiency, as well as starting behavior.

What are the advantages of electronic ignition systems?

A variety of extra features are available on such systems, which can be accessed and adjusted by a computer. Electronic Ignition systems provide extremely accurate spark timings, leading to improved combustion and emissions control. As there is no mechanical contact there is no wear therefore the accuracy is maintained.

Do electronic ignition systems require a distributor?

Modern electronic ignition systems do not require a distributor. A single small HT coil is used for each spark plug and the igniter operates each coil separately in the correct sequence.
