What does an electronic ignition system improve?

An electronic ignition system primarily improves power and fuel economy in internal combustion engines. By using electronic controls, this system can provide a more precise timing of the spark that ignites the fuel-air mixture in the engine's cylinders. This precision allows for optimal combustion, which translates to better engine performance, resulting in increased power output. Furthermore, with optimal combustion efficiency, the engine can convert fuel into energy more effectively, which leads to improved fuel economy as less fuel is wasted or unburned.

While an electronic ignition system does not directly affect engine size, mechanical efficiency, or tire longevity, its impact on power generation and fuel efficiency makes it a critical component in modern vehicles aimed at both performance enhancement and environmental considerations.
