Differences Between DC Ignition and AC Ignition for Motorcycles
1 Answers
Differences between DC ignition and AC ignition: 1. Power supply method: AC ignition is powered by the stator coil of the magneto, while DC ignition is powered by the battery or rectifier. By checking whether the power supply line to the ignition comes from the magneto or the battery, you can determine whether it is an AC or DC ignition. 2. Shutdown method: AC ignition shuts down by short-circuiting the ignition signal line to ground. The ignition has a shutdown wire connected to the shutdown switch; closing the shutdown switch grounds the circuit to shut it down. In contrast, DC ignition shuts down by cutting off the DC power supply, achieved by turning off the shutdown switch. 3. Input voltage: DC ignition performs better in cold starts, while both types perform similarly in hot starts. 4. Ignition voltage: DC ignition provides stronger ignition energy and faster performance acceleration compared to AC ignition. 5. Fuel efficiency: DC ignition has higher ignition energy and significantly better acceleration performance than AC ignition, making it more fuel-efficient.
