Question

what function is performed by the ignition system?
a) increases voltage from 12 volts to more than 20,000 volts.
b) ensures voltage is delivered to each cylinder at the correct time.
c) sends high voltage to each spark plug.
d) all of above.

Explanation:

The ignition system in an internal - combustion engine has multiple functions. It steps up the low - voltage (usually 12 volts) from the battery to a high voltage (more than 20,000 volts) to create a spark. It also ensures that the high - voltage is delivered to each cylinder at the correct time and sends this high voltage to each spark plug to ignite the air - fuel mixture.

Answer:

D. All of above
