Sample questions

1. The start-up electric motor (the starter):

   • generates electric current
   • consumes electric current from the accumulator battery

2. Starting an internal combustion engine means:

   • the initial cranking of the crank shaft with the aim to initiate a working cycle
   • turning the distributing shaft with the aim to initiate a working cycle
   • ignition of the fuel mixture

3. The function of the starter assembly of an internal combustion engine is to assure the initial cranking of the internal combustion engine crank shaft.

   • correct
   • incorrect

4. The nuts of the pole terminals of the accumulator battery are tightened:

   • on a stand
   • by hand
   • by a wrench

5. The generator is powered by:

   • the accumulator battery
   • by a power elimination shaft
   • by the engine by means of belt transmission

6. The terminals of the accumulator battery are protected against oxidation by:

   • an antifreeze solution
   • gasoline
   • technical petroleum jelly

7. Electrolyte spilled from a lead accumulator battery is cleaned by:

   • gasoline
   • warm water
   • water solution of sodium bicarbonate

8. It is recommended to check the level of electrolyte in a lead accumulator battery with a non-transparent box:

   • by a glass level metering tube
   • by the oil dip- stick
   • by the reading of the ammeter

9. The generator transforms:

   • thermal into electric energy
   • chemical into electric energy and vice versa
   • mechanical into electric energy

10. For proper removal of the accumulator battery:

    • the positive terminal is disconnected first, followed by the negative terminal
    • the negative terminal is disconnected first, followed by the positive terminal
    • the sequence of disconnecting the terminals is of no importance
