Evolution of Ignition Systems Quiz

What is the main advantage of a wasted spark ignition system over a distributor-based system?

• Individual control of ignition timing for each cylinder

• Higher voltage at high rpms

• No need for spark plug wires

• Mechanical synchronization with the engine

What is the purpose of a crankshaft position sensor in a wasted spark ignition system?

• To control the operation of the ignition coil

• To generate high voltage for the spark plug

• To regulate the fuel-air mixture in the engine

• To sense the position of the engine for ignition timing

What is the key benefit of a coil-on-plug (COP) ignition system compared to a wasted spark system?

• No need for crankshaft position sensor

• Each cylinder gets its own ignition coil

• Higher voltage at high rpms

• Mechanical synchronization with the engine

Why is a monster coil like the AEM Smart Coil used in highly modified engines?

• To generate 40,000 volts for reliable spark under high boost

• To eliminate the need for a crankshaft position sensor

• To increase the number of cylinders fired by each ignition coil

• To reduce the engine's red line for better performance

What is the downside of using a monster coil like the AEM Smart Coil?

• It uses spark plug wires

• It cannot handle high rpms

• It requires mechanical synchronization with the engine

• It has limited voltage output

In a coil-on-plug (COP) system, why does each cylinder having its own ignition coil lead to better engine performance?

• Increased friction between moving parts

• Reduced voltage drop due to equal length spark plug wires

• Higher chance of misfires at high rpms

• More time to recharge and produce voltage at high rpms

What is the role of the ignition coil in the ignition system?

• To increase voltage and current flow to the spark plug

• To regulate the fuel-air mixture in the engine

• To mechanically synchronize with the engine internals

• To control the operation of the crankshaft position sensor
