What is the function of the ignitor leads in the engine ignition system?

• A. Provides mechanical support to the engine
• B. Delivers power to ignitor plugs
• C. Stores electrical energy
• D. Filters impurities in fuel

Answer: (B)

The function of the ignitor leads in the engine ignition system is to deliver power to the ignitor plugs. Ignitor plugs are crucial for initiating the combustion process in the engine by creating a spark that ignites the fuel-air mixture. The ignitor leads act as electrical conduits, transferring high-voltage electricity from the ignition system to the ignitor plugs when needed. Ensuring a reliable connection and proper delivery of power to these plugs is essential for the engine to start and maintain operation.

In the context of the other choices, while mechanical support is important in an engine, ignitor leads do not provide this function. Storing electrical energy is a role more associated with components like batteries or capacitors, not ignitor leads. Additionally, filtering impurities in fuel is relevant to fuel systems and not related to the ignition of the engine. Thus, the primary and correct role of the ignitor leads is to facilitate the delivery of power to the ignitor plugs for effective engine ignition.
