Question 24

What’s the name of the component that transfers high current during START from battery to starter motor

Answer 24

Solenoid (Not true probably)

Question 25

Spark advance

Answer 25

Spark occuring slightly before reaching the head of the cylinder (TDC)

Question 26

Impulse coupling

Answer 26

Magneto. With primary coil and secondary coil, the primary coil shuts off causing a very high voltage spark in the secondary coil.
Generates a high voltage
Retards the ignition timing to to start the engine

Hobbs meter

Answer 28

Counts the time from engine start (or battery on)

Question 29

Diesel benefits

Answer 29

• Cheaper
• Ecofriendlier
• Self igniting (does not need spark plugs, fuel is ignited through compression)
