Inductive energy storage ignition system

How does an inductive ignition system work?

The inductive ignition system generates in each power stroke the high voltage required for flash -over and the spark duration required for ignition. The electrical energy drawn from the vehicle electrical system battery is tem-porarily stored in the ignition coil for this purpose.

What is the inductive discharge ignition system?

Figure 1. The Inductive Discharge Ignition system Before we discuss the IDI in detail, remember that the spark event in the combustion chamber of the gasoline engine is controlled by the ignition system. At the heart of the ignition system is the Ignition Insulated-Gate Bipolar Transistor (Ignition IGBT).

What is a transistor-switched inductive ignition system?

In summary, the transistor-switched inductive ignition system, with its low cost and high reliability, is well suited to providing the low ignition energy sparks required by current spark ignition engines using stoichiometric and low-dilution mixtures.

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.

What is a high energy ignition system?

The energies delivered to the gases in the spark gap are usually of the Application of high energy ignition systems to engines order of 30 mJ, which is 10-100 times greater than the minimum ignition energy for combustible fuel-air mixtures under ideal conditions.

When was the inductive ignition system invented?

In the early 1900s, the inductive ignition system was developed for internal combustion engines. The system and its variants have been in use since that time. In the early days, the primary winding of the ignition coil was controlled by mechanical switches, commonly called the breaker points, which are seldom seen in modern ignition systems.
