Question 1

Cylinder number one always starts the firing order.

Accepted Answer

Cylinder number one is typically the reference point for determining the firing order of an engine. The firing order is the sequence in which the cylinders fire, and it is important for ensuring the engine runs smoothly and efficiently.

Question 2

Higher octane gas is more easily ignited by the ignition system than lower octane fuel.

Accepted Answer

Higher octane fuel is actually more resistant to ignition, which allows engines with higher compression ratios to operate without knocking.

Question 3

Electronic switching devices like Hall-effect sensors completely eliminate the need for ________.&#10;A)ignition coils&#10;B)pulse generators&#10;C)breaker points&#10;D)reluctors

Accepted Answer

B

Question 4

When the motorcycle is under a heavy load the ignition timing must be retarded.

Accepted Answer

Retarding the ignition timing under heavy load conditions helps prevent engine knock or pinging, which can occur due to the increased pressure and temperature inside the combustion chamber.

Question 5

Older motorcycle ignition systems were equipped with a(n)________advance mechanism.&#10;A)electronic&#10;B)vacuum&#10;C)centrifugal&#10;D)manual

Accepted Answer

Older motorcycle ignition systems commonly used a centrifugal advance mechanism, which automatically adjusted the timing of the spark based on the engine's speed.

Question 6

High turbulence in the combustion chamber requires that ignition must be slightly retarded.

Accepted Answer

High turbulence in the combustion chamber promotes faster flame propagation, which requires ignition to be slightly retarded to prevent knocking.

Question 7

In motorcycle ignition systems there are just two power sources, the battery or a(n)_________.&#10;A)capacitor&#10;B)AC generator&#10;C)pulser coil&#10;D)magnet

Accepted Answer

Motorcycle ignition systems can use a battery or an AC generator (alternator) as their power sources. The AC generator provides electrical power while the engine is running, supplementing or replacing the battery's supply.

Question 9

The ignition timing marks are located on the&#160;&#160;______.&#10;A)flywheel&#10;B)camshaft&#10;C)counter sprocket&#10;D)connecting rod

Accepted Answer

The ignition timing marks are typically located on the flywheel, which is a component of the engine used to store rotational energy and help with timing and ignition processes.
