What is the primary function of a motorcycle ignition system?

• To provide power to the motorcycle's headlights.

• To control the speed of the motorcycle.

• To charge the battery while the engine is running.

• To generate a spark for igniting the air-fuel mixture in the engine.

Which component generates the high voltage needed for the spark plug?

• Battery

• Ignition coil

• Starter motor

• Fuel injector

What does CDI stand for in motorcycle ignition systems?

• Coil Discharge Ignition

• Capacitor Discharge Ignition

• Capacitor Direct Ignition

• Current Discharge Ignition

What is the role of a spark plug in an engine?

• To provide electrical power to the vehicle.

• To filter the air entering the engine.

• The role of a spark plug in an engine is to ignite the air-fuel mixture in the combustion chamber.

• To cool the engine by circulating coolant.

Which sensor is commonly used in fuel injection systems?

• Mass Air Flow (MAF) sensor

• Throttle Position Sensor

• Oxygen Sensor

• Coolant Temperature Sensor

What is the purpose of the ignition coil?

• To cool the engine temperature.

• To generate high voltage for the spark plugs.

• To charge the car battery.

• To regulate fuel flow to the engine.

How does a CDI unit control the timing of the spark?

• A CDI unit relies on fuel type to determine spark timing.

• A CDI unit uses a mechanical lever to adjust spark timing.

• A CDI unit controls spark timing by monitoring engine parameters and discharging a capacitor at the optimal moment.
