Four-Stroke Engine: Electrical System - Final Assessment

For proper high-speed operation, the ignition spark should occur when?

• At top dead center

• Five degrees after top dead center

• 15 to 30 degrees before top dead center

• 40 to 50 degrees before top dead center

According to the presentation, advanced ignition timing could result in which of the following?

• Detonation

• Increased exhaust emissions

• Incomplete combustion

• Lower fuel output

A one-way electrical gate which allows electrical current to flow in one direction only correctly defines which of the following?

• DC current

• AC current

• Solenoid

• Diode

What is the difference between primary and secondary circuits?

• The secondary circuit has more power than the primary circuit

• The primary circuit generates the spark while the secondary circuit delivers the spark to the spark plug

• The primary circuit is considered low voltage while the secondary circuit is considered high voltage

• The secondary circuit does not utilize a spark plug, while the primary circuit does

In a capacitor discharge ignition system the (a)   is triggered, creating a path to ground through a coil.

• Primary circuit
