The heart of any engine lies in its ignition system. The whole idea of the power of a machine lies in this simple mechanism of physics.

Today a wide variety of ignition systems are being used all around the globe. One of the most used ones is the fire ignition system.

This system is also used by Harley Davidson in their manufacturing of many motorcycle models.

Types of Fire Ignition

Fire Ignitions are classified into various types based on automaticity, source of ignition, and a number of coils. On the basis of coils, they are classified as

Single Fire Ignition

A single fire Ignition is built upon two separate coils for both cylinders. It fires each spark plug independently to generate power for the engine.

A single fire ignition saves extra energy that is wasted in the backfiring of the cylindrical shafts of the engine.

Dual Fire Ignition

A dual fire ignition uses a single coil for both cylinders to start the engine. This is more economical for those who don’t want to spend too much on upgrading their motorcycles.

Is single fire or dual fire ignition better?

Dual fire is more of a simple ignition with low cost and a single fire provides a better smooth ride.
